a &# 34 ;, since the portion of the outline is &# 34 ; 1 &# 34 ;, and the selected part pattern number is &# 34 ; 01 &# 34 ;, the montage data about this outline becomes &# 34 ; 101 &# 34 ;. furthermore , since the portion of the hair style is &# 34 ; 2 &# 34 ;, and the selected part pattern number is &# 34 ; 02 &# 34 ;, the montage data about this hair style becomes &# 34 ; 202 &# 34 ;. thus , the part numbers may be stored as the montage data for the respective parts in such a manner . on the other hand , the fighting power data ram 40 is arranged by a basic fighting power data register 40a , a fighting power determining coefficient register 40b , a determined fighting force data register 40c , a data register 40d for life force after attacking , and a data register 40e for life force after recovery . the basic fighting force data register 40a stores therein fighting force data which constitutes a base of a selected fighter , and has been registered by a user in the battle fighter register mode . the fighting power data is classified into life force data , attacking force data , and defensive force data , which will then be stored into the basic attacking force data register 40a . in this case , two digits of the lower digit portion of the corresponding montage data are allocated to the life force data and the attacking force data , whereas the first digit of the upper digit portion thereof is allocated to the defensive force data . for example , when an &# 34 ; a &# 34 ; is registered as the selected fighter in the individual data ram 39 , since the montage data corresponding to the portion of the outline is &# 34 ; 101 &# 34 ;, the above - described fighting power data becomes &# 34 ; 1 &# 34 ;, &# 34 ; 0 &# 34 ;, &# 34 ; 1 &# 34 ; in the order of the defensive force data , the attacking force data , and the life force data . also , since the montage data corresponding to the portion of the hair style is &# 34 ; 202 &# 34 ;, the above - mentioned fighting power data becomes &# 34 ; 2 &# 34 ;, &# 34 ; 0 &# 34 ;, &# 34 ; 2 &# 34 ; in the order of the defensive force data , the attacking force data , and the life force data . these numeral values are stored as the respective data . then , the fighting power determining coefficient register 40b is subdivided into a life force coefficient register 40b1 , an attacking force coefficient register 40b2 , and a defensive force coefficient register 40b3 . into the life force coefficient register 40b1 , the first digit value of the total value about the life force data allocated to the basic fighting power data register 40a is stored as the life force determining coefficient &# 34 ; a &# 34 ; of the selected fighter . into the attacking force coefficient register 40b2 , the first digit value of the total value about the attacking force data is stored as the attacking force coefficient &# 34 ; b &# 34 ; of the selected fighter . furthermore , into the defensive force coefficient register 40b3 , the first digit value of the total value of the defensive force data is stored as the defensive force determining coefficient &# 34 ; c &# 34 ; of the selected fighter . when the total value of the life force data stored in the basic fighting power data register 40a is , for instance , &# 34 ; 123 &# 34 ;, the above - explained life force determining coefficient &# 34 ; a &# 34 ; is &# 34 ; 3 &# 34 ; corresponding to the first digit value of this total value &# 34 ; 123 &# 34 ;. when the total value of the attacking force data stored in the basic fighting power data register 402 is , for example , &# 34 ; 26 &# 34 ;, the attacking force determining coefficient &# 34 ; b &# 34 ; is &# 34 ; 6 &# 34 ; corresponding to the first digit value of this total value &# 34 ; 26 &# 34 ;. also , when the total value of the attacking force data stored in the basic fighting power data register 40a is , e . g ., &# 34 ; 135 &# 34 ;, the attacking force determining coefficient &# 34 ; c &# 34 ; is &# 34 ; 5 &# 34 ; corresponding to this total value of &# 34 ; 135 &# 34 ;. also , the determined fighting power data register 40c is subdivided into a life force data register 40c1 , an attacking force data register 40c2 , and a defensive force data register 40c3 . into the respective registers 40c1 , 40c2 , and 40c3 , life force data ( esp ) of the selected fighter , attacking force data ( pk ) thereof , and defensive force data ( tp ) thereof are stored which have been calculated based on a calculation formula for determining the fighting power data previously stored into the calculation formula rom 34 . in this case , the calculation formula to determine the life force is given by the below - mentioned formula ( 1 ): the calculation formula to determine the attacking force is given by the following formula ( 2 ): further , the calculation formula to determine the defensive force is given by the following formula ( 3 ): as a consequence , when the life force determining coefficient &# 34 ; a &# 34 ; is &# 34 ; 3 &# 34 ;, which is stored in the fighting power determining coefficient register 40b in correspondence with the selected fighter &# 34 ; a &# 34 ;, the life force data ( esp ) thereof becomes ( 30 , 000 ) calculated based on the above - explained formula ( 1 ). when the attacking force determining coefficient &# 34 ; b &# 34 ; is &# 34 ; 6 &# 34 ;, the attacking force data ( pk ) thereof becomes ( 6 , 000 ) calculated based upon the above - described formula ( 2 ). furthermore , when the defensive force determining coefficient &# 34 ; c &# 34 ; is &# 34 ; 5 &# 34 ;, the defensive force data ( tp ) becomes ( 5 , 000 ) calculated based on the above - mentioned formula 3 . these numeral values are stored into the respective registers 40c1 to 40c3 for constituting the determined fighting force data register 40c . the data register 40d for life force after attacking stores therein the remaining amount of the life force data after the attacking from the confronted fighter . in this case , the remaining amount of the life force after the respective fighters have attacked , is calculated based on a calculation formula ( 4 ) about the life force data after attacking , which has been previously stored in the attacking formula rom 35 : life force data after attacking = life force before attacking - attacking point for confronted fighter ( bp ) ( 4 ). it should be noted that the attacking point for attacking fighter ( bp ) may be calculated based on the following formulas ( 5 ) and ( 6 ). the first formula ( 5 ) is a basic value calculating formula which has been previously stored in the attacking formula rom 35 : basic value = attacking force data for attacking fighter ×( 1 - defensive force for confronted fighter / 20 , 000 )× 4 ( 5 ). also , the second formula ( 5 ) is an attacking point calculating formula : the data register 40e for life force after recovery stores therein the life force data recovered in accordance with the life force recovery point ( refer to fig4 ) selected in the life force recovery mode . this life force data after recovery is updated as life force data ( esp ) of the determined fighting force data register 40c . here , the above - described life force after recovery is calculated based on a life force recovery formula ( 7 ) previously stored in the calculation formula rom 24 : that is , both of the newly entered individual data and the montage data thereof are stored in the individual data ram 39 . the fighting power of the selected fighter is stored as the life force data ( esp ), the attacking force data ( pk ), and the defensive force data ( tp ) in the fighting power data ram 40 . it should be understood that a plurality of montage data about the fighters on the side of the computer , who are confronted with the fighters selected by the user , have been previously stored in a rom ( not shown ), and then the fighting power data , the respective determining coefficients for life force , attacking force , and defensive force , and the various data about life force data ( esp ), attacking force data ( pk ), defensive force data ( tp ), and the life force after attacking data , which belong to the computer fighters successively selected as the confronted fighters , can be obtained in a similar manner to those of the above - described selected fighters . on the other hand , display part patterns at the respective battle win / lose determining stage have been stored in the expression part pattern rom 37 . that is , face expression changing part patterns corresponding to the eyes and mouth basic part patterns in the basic part pattern rom 33 have been previously stored . also , win / lose messages varied in response to the battle results have been stored in the battle message rom 38 in addition to the message data required during the battle game . for instance , a message &# 34 ; you did it !&# 34 ; has been previously stored as the message displayed in combination with the face montage for the winner , and another message &# 34 ; sorry , try again !&# 34 ; has been previously stored as the message displayed in combination with the face montage for the loser . on the other hand , the respective part patterns read out from the basic part pattern rom 33 are synthesized in correspondence with the part pattern numbers for the respective parts which constitute the montages of the selected fighters and the computer fighters stored in the corresponding individual data ram 39 and computer fighter rom ( not shown ), and thereafter the combined part patterns are stored in the display ram 43 . a portrait image and the like are supplied via the display drive circuit 42 to the liquid crystal dot matrix display unit 42 as to be displayed thereon adjacent to the above - described part patterns ( see fig1 ). overall process operation of the above - described montage battle game apparatus with these arrangements will now be described with reference to a flow chart shown in fig6 . before executing the montage battle game , an input / register process operation ( see fig7 ) of individual data is carried out at a first step x1 . at this step x1 , arbitrary individual data is inputted as his name , address , telephone number , and age . at the next step x2 , a montage forming process operation ( see fig8 and fig9 ) is carried out , in which a portrait image of the respective individual data is formed and montage data corresponding to this individual data is registered . thereafter , at a step x3 , a battle fighter register process operation ( see fig1 and fig1 ) is performed , and furthermore another process operation is executed so as to set fighting power data about a selected fighter and a computer fighter . after the above - described various process operations have been executed , a battle game process operation ( see fig1 to fig1 ) is carried out at a step x4 . at this step x4 , the battle game for the above - explained selected fighter battled with the computer fighter . this battle game is performed until the game stop key 21 is manipulated by repeatedly executing the above - explained battle game process operation ( steps x5 to x4 ). in fig7 there is shown a flow chart for explaining the contents of the above - described individual data input / register process operation as defined at the step x1 of fig6 . at a first step y1 of this flow chart , when a judgement result is made that the individual key 14a in the input unit 32 is operated , the cpu 31 sets the operation mode to the individual data input mode . in this individual data input mode , when it is so judged at a step y2 that such individual data as a name , an address , a telephone number , and an age are entered in accordance with the operations of the numeral entry key 25 and the alphabet entry key 27 , these entered individual data are sequentially stored into the individual data register 39a in the individual data ram 39 at a step y3 . at the subsequent step y4 , when the register key 18 is manipulated , the individual data input mode is released , so that registers of the respective individual data stored in the individual data register 39a are confirmed . fig8 is a flow chart for representing the contents of the above - explained montage forming / register process operation as defined in the step x2 of fig6 . at a first step s1 of this flow chart , when the montage forming key 14b employed in the input unit 32 is operated , the operation mode of the cpu 31 is brought into the montage forming mode . when the montage forming mode is in effective , the part pattern number &# 34 ; 01 &# 34 ; corresponding to the respective part patterns for constituting the first basic type montage image is set to the basic part pattern rom 33 ( see fig3 ) at a step s2 . also , the first part number ( namely , part number of outline in this case ) is set as the part used to change the pattern . as a consequence , the respective part patterns corresponding to the first basic type montage image are read out from the basic part pattern rom 33 . thereafter , these read part patterns are transferred to the display ram 43 and are combined with each other at the next step s3 . as a result , the combined part patterns are displayed as the first basic type montage image on the liquid crystal dot matrix display unit 24 at a step s4 . referring now to a flow chart of fig9 a detailed process operation of the above - described data combining ( synthesizing ) process operation as defined at the previous step s3 of fig8 will be explained . in this data synthesizing process , when the part pattern numbers of the respective parts are designated to the basic part pattern rom 33 in order to constitute the first basic type montage image , the part pattern data corresponding to the designated part pattern numbers are read out from the basic part pattern rom 33 , and then are transferred to the display ram 43 in which the contents of these part pattern data are synthesized with each other ( steps a1 to a5 ). in this case , the respective part patterns such as the outline , eyes , and nose which constitute the first basic type montage image are sequentially synthesized in the display ram 43 . as a result , with respect to this initial setting operation , the first basic type montage image constructed by the respective parts and the respective part patterns corresponding to the part pattern number &# 34 ; 01 &# 34 ;, is displayed on the liquid crystal dot matrix display unit 24 ( step a6 ). under this condition , when the basic montage selecting key 15b employed in the input unit 32 is operated , all of the respective part pattern numbers for designating the basic type montage image to the basic part pattern rom 33 are changed from &# 34 ; 01 &# 34 ; to &# 34 ; 02 &# 34 ; ( steps s5 and s6 ). as a consequence , in accordance with the changed part pattern number &# 34 ; 02 &# 34 ;, after the respective part pattern data stored in the basic part pattern rom 33 have been read out ( in this case , all numbers are &# 34 ; 02 &# 34 ;), the transfer / synthesizing process operation of the respective part patterns with respect to the display ram 43 is carried out . accordingly , the second basic type montage image is displayed on the liquid crystal dot matrix display unit 24 at the steps s3 and s4 . this second basic type montage image is constructed by synthesizing the part patterns corresponding to the part pattern number &# 34 ; 02 &# 34 ; which involves all of the part patterns from the outline part pattern to the mouth part pattern . when the basic montage selection keys 15a and 15b employed in the input unit 32 are sequentially operated , the process operation defined at the steps s3 to s6 is repeatedly carried out , so that 20 sorts of basic type montage images previously stored as the part pattern numbers of &# 34 ; 01 &# 34 ; to &# 34 ; 20 &# 34 ; in the basic part pattern rom 33 are sequentially changed and sequentially synthesized with each other , and finally are displayed . as a consequence , the user can previously select either such a desirable montage image itself , or one basic type montage image similar to this desirable montage image to be displayed on the liquid crystal dot matrix display unit 24 . under this display condition , when the part designation keys 16a and 16b employed in the input unit 32 are operated , the parts whose patterns should be changed , will be changed into other parts . for instance , when a specific part ( for example , outline part ) among the basic type montage images selectively and previously displayed on the liquid crystal dot matrix display unit 24 by executing the process operation defined at the steps s3 to s6 , is desired to be changed into another different part ( e . g ., hair part ), this specific part is changed by operating the part designation keys 16a and 16b ( steps s7 and s8 ). thereafter , when the pattern selection keys 17a and 17b are operated , the part pattern is changed among the corresponding parts of the basic part pattern rom 33 , which are designated as the parts to be changed . this changed part pattern is read out from the basic part pattern rom 33 and then transferred to the display ram 43 . thus , the presently displayed part pattern on the liquid crystal display unit 24 may be substituted by the transferred part pattern , and then this transferred part pattern is displayed thereon ( steps s9 , s10 , to s3 , s4 ). as a consequence , the user may change the desired part into another different part among the basic type montage images selectively , previously displayed on the liquid crystal display unit 24 , and then may display this different part on this display unit 24 . furthermore , when this different part is changed into the other part pattern , the part designation keys 16a and 16b are operated to change the part to be change . thereafter , the pattern selection keys 17a and 17b are operated to change the part pattern number , whereby the part among the presently displayed basic type montage images is changed into other part pattern , and then a desired montage image can be finally formed . at the steps s5 through s10 , for instance , as the respective part patterns of the montage image corresponding to the individual data &# 34 ; a &# 34 ;, the outline part pattern is selected as &# 34 ; 01 &# 34 ;; the hair style part pattern is selected as &# 34 ; 02 &# 34 ;; . . . , the nose part pattern is selected as &# 34 ; 04 &# 34 ;; the mouth part pattern is selected as &# 34 ; 01 &# 34 ;; and also the wear part pattern is selected as &# 34 ; 03 &# 34 ;. after the montage image desired by the user could be obtained , when it is judged at a step s11 that the register key 18 of the input unit 32 is operated , the part pattern numbers corresponding to the respective part patterns for constituting the synthesized montage image in the display ram 43 are registered into the montage data register 39b within the individual data ram 39 as the montage data corresponding to , for instance , the first individual data &# 34 ; a &# 34 ; at the step s12 . fig1 and fig1 are flow charts for explaining the detailed contents of the battle fighter register process operation as defined at the above - described step x3 shown in fig6 . at a first step b1 of the flow chart shown in fig1 , when a judgement result is made that the battle key 19 employed in the input unit 32 is operated during the battle fighter register process operation , the operation mode of the cpu 31 is set to the battle fighter register mode . thereafter , the names of the respective individual data stored in the individual data register 39a of the individual data ram 39 are transferred to the display ram 43 in a predetermined format at the next step b2 . then , as shown in fig1 a , these individual names are displayed as a list of fighters to be selected , on the liquid crystal dot matrix display unit 24 in combination with such a character data &# 34 ; is fighter selected &# 34 ; read out from the battle message rom 38 . under such a display condition , the fighter selection keys 16a and 16b are operated at a step b3 to select &# 34 ; a &# 34 ; as the selected fighter 51a , as illustrated in fig1 b . accordingly , the montage data corresponding to this individual name &# 34 ; a &# 34 ; is read out from the montage data register 39b of the individual data ram 39 at a step b4 , so that a portrait of this selected fighter 51a is displayed in combination with his name &# 34 ; a &# 34 ; ( see fig1 c ). in case of this portrait , since the respective part pattern numbers stored in the montage data register 39b in correspondence with the selected fighter whose name is &# 34 ; a &# 34 ;, are given such that the outline is &# 34 ; 01 &# 34 ;, the hair style is &# 34 ; 02 &# 34 ;, . . . , the nose is &# 34 ; 04 &# 34 ; the mouth is &# 34 ; 01 &# 34 ;, . . . , the corresponding part patterns are read out from the basic part pattern rom 33 in accordance with these part pattern numbers . then , the read part patterns are synthesized with each other in the display ram 43 and the synthesized part patterns are displayed on the display unit 24 . under such a condition that , as represented in fig1 c , the selected fighter 51a whose name is &# 34 ; a &# 34 ; is selected and his portrait is displayed , when the ok key 23 is manipulated at a step b5 , the montage data &# 34 ; 101 &# 34 ;, &# 34 ; 202 &# 34 ;, . . . , &# 34 ; 504 &# 34 ; and &# 34 ; 601 &# 34 ; corresponding to this selected fighter 51a having his name of &# 34 ; a &# 34 ; are read out from the montage data register 39b . at the next step b6 , these read montage data are allocated and stored into the basic fighting power data register 40a of the fighting power data ram 40 as the life force data , the attacking force data , and the defensive force data for the respective parts . at the next step b7 , a total value of each of the life force data , the attacking power data , and the defensive force data of the selected fighter stored in the basic fighting power data register 40a is calculated by the cpu 31 . then , the first digit values of the respective total values are stored as the life force determining coefficient &# 34 ; a &# 34 ;, the attacking force determining coefficient &# 34 ; b &# 34 ;, and the defensive force determining coefficient &# 34 ; c &# 34 ; into the relevant coefficient registers 40b1 to 40b3 in the fighting power determining coefficient register 40b . thus , when the respective fighting power determining coefficients &# 34 ; a &# 34 ;, &# 34 ; b &# 34 ;, &# 34 ; c &# 34 ; could be obtained , calculations are performed for the life power data ( esp ), the attacking power data ( pk ), and the defensive force data ( tp ) about the selected fighter 51a based on the life power determining calculation formula ( formula 1 ), the attacking force determining calculation formula ( formula 2 ), and the defensive force determining calculation formula ( formula 3 ), which have been previously stored into the calculation formula rom 34 at a step b8 . the resultant data esp , pk , tp are stored into the corresponding registers 40c1 to 40c3 in the determined fighting power data register 40c . at the next step b9 , as represented in fig1 d , these calculated data of the selected fighter 51a about the life force ( esp ), the attacking force ( pk ), the defensive force ( tp ) are displayed in combination with the portrait of this selected fighter 51a on the liquid crystal display unit 24 . after the selected fighter by the user is registered in the above - described manner to set the fighter power data thereof , when it is judged at a step b10 that a lapse of 1 second is counted by a timer built in the cpu 31 , the montage data corresponding to the first computer fighter is read from plural sets of the montage data previously stored in a montage rom ( not shown ) for the computer fighter . then , the various fighting power data esp , pk , tp about this first computer fighter are calculated based on the read montage data in a similar manner to that of the above - described selected fighter at the subsequent step b11 . thereafter , at a step b12 , only the life force data ( esp ) among the fighting power data of the computer fighter 51b is displayed on the liquid crystal display unit 24 in combination with the portrait of this computer fighter 51b synthesized based on the montage data corresponding to the first ( level - 1 ) computer fighter , as represented in fig1 e . both the attacking force data ( pk ) and the defensive force data ( tp ) other than this life force data ( esp ) are not displayed , but symbol data of &# 34 ;??? ?&# 34 ; are alternatively displayed . thereafter , when at a step b13 , it is so judged that a lapse of 1 second is counted by the timer built in the cpu 31 , the random numbers of 0 to 9 are generated by the random number generating unit 41 at a step b14 . depending upon such a fact as to , for instance , whether the generated random number corresponds to the even number , or the odd number , a decision is made who is the first attacker for the above - described selected fighter 51a and computer fighter 51b . at the next step b15 , as shown in fig1 f , a life force representing bar 52a for the selected fighter 51a and a life force representing bar 52b for the computer fighter 51b , which indicate remaining amounts of the respective life force based on these life force data ( esp ), are displayed in addition to the respective portraits of the fighters 51a and 51b . in correspondence with the above - described first attacker decision , an attacking arrow 53a indicative of the attacking direction between these fighters is displayed . in case of fig1 f , the attacking arrow 53a indicates that the selected fighter is the first attacker . as described above , when the user selected fighter and the computer fighter are registered , such a condition that the battle game can be performed can be established . a battle process operation for the montage battle gate as defined at the step x4 of fig6 will now be described with reference to flow charts shown in fig1 to fig1 . at a first step c1 of the flow chart shown in fig1 , when it is judged that the game start key 20 is operated , the operation mode of the cpu 31 is set to the battle game mode . thereafter , as shown in fig1 g , such a figure which represents the selected fighter under attacking is displayed at a step c2 in accordance with the bit map pattern previously stored in the rom . at the subsequent step c3 , the random numbers &# 34 ; 0 &# 34 ; to &# 34 ; 9 &# 34 ; are produced from the random number generating unit 41 . these random numbers are substituted for the random numbers of the attacking point calculation formula ( formula 6 ) different from the basic value calculation formula ( formula 5 ) previously stored in the attacking formula rom 35 , and the attacking point ( bp ) for the selected fighter 51a is calculated based upon this attacking point calculation formula ( 6 ). on the other hand , in response to the above - explained process operation , the computer fighter 51b is attacked by the selected fighter 51a based on the calculated attacking point ( bp ) of the selected fighter 51a . then , a step c4 , new life force data ( esp ) of the computer fighter 51b who has received the attack made by the selected fighter 51a by way of substituting the above - described attacking point ( bp ) value of the selected fighter 51a for another attacking point ( bp ) of the calculation formula ( 4 ) for the life force data after attacking which has been previously stored in the attacking formula rom 35 . at the next step c5 , as illustrated in fig1 h , there are displayed the portrait of the selected fighter 51a , the life force representing bar 52a corresponding to the attacking life force data ( esp ), the portrait of the computer fighter 51b , and the life force representing bar 52b for the computer fighter , corresponding to the life force data ( esp ) after attacking , which has been calculated at the previous step c4 . also , another attacking arrow 53b indicative of the attacking direction by the computer fighter 51b as the second fighter is displayed . at the subsequent step c6 , when it is judged that a predetermined time period has been measured by the cpu 31 , such a figure that the computer fighter 51b is attacking is displayed in accordance with the bit map pattern previously stored in the rom at a step c7 ( see fig1 i ). then , at a further step c8 , the random numbers &# 34 ; 0 &# 34 ; to &# 34 ; 9 &# 34 ; are produced from the random number generating unit 41 . these random numbers are substituted for the random numbers of the attacking point calculation formula ( formula 6 ) different from the basic value calculation formula ( formula 5 ) previously stored in the attacking formula rom 35 , and the attacking point ( bp ) for the computer fighter 51b is calculated based upon this attacking point calculation formula ( 6 ). on the other hand , in response to the above - explained process operation , the selected fighter 51a is attacked by the computer fighter 51b based on the calculated attacking point ( bp ) of the computer fighter 51b . then , a step c9 , new life force data ( esp ) of the selected fighter 51a who has received the attack made by the computer fighter 51b by way of substituting the above - described attacking point ( bp ) value of the computer fighter 51b for another attacking point ( bp ) of the calculation formula ( 4 ) for the life force data after attacking which has been previously stored in the attacking formula rom 35 . this calculated life force data ( esp ) is stored into the life force data after attacking register 40d , and is updated as life force data ( esp ) of the determined fighting power data register 40c . at the next step c10 , as illustrated in fig1 j , there are displayed the portrait of the selected fighter 51a , the life force representing bar 52a for the selected fighter , corresponding to the life force data ( esp ) after attacking calculated at the step c9 , the portrait of the computer fighter 51b , and the life force representing bar 52b for the computer fighter . also , another attacking arrow 53b indicative of the attacking direction by the selected fighter 51a as the fighter is displayed . thereafter , at a step c11 , when it is judged that the life force recovery key 22 is operated , the process operation is advanced to the life force recovery process operation ( fig1 ) in which the life force data ( esp ) of the selected fighter 51a may be recovered . either after the recovery process operation of the life force data ( esp ) has been performed , or while the life force recovery key 22 is not yet operated , until the value of the life force data ( esp ) for either the selected fighter 51a , or the computer fighter 51b becomes &# 34 ; 0 &# 34 ;, the above - described attacking operation between the selected fighter 51a and the computer fighter 51b as defined at the steps c2 to c10 is repeated ( steps c13 , c2 to c10 ). on the other hand , when the value of the life force data ( esp ) of the computer fighter 51b becomes , e . g ., &# 34 ; 0 &# 34 ;, while repeating the attacking operation between the respective fighters at the previous steps c2 to c10 , as shown in fig1 a , the portrait of the selected fighter 51a and also the life force representing bar 52a are displayed . at the same time , the present portrait of the computer fighter 51b is substituted by another portrait indicative of loser &# 39 ;
