This phrase is from a jrpg set in feudal japan. Is "わけわかんねーよ!" some shortened
casual form of speech? Is わかんね is short for わからない? What is the grammar for it?
Is it right to translate it like "I don't understand meaning!"

Is "わけわかんねーよ!" some shorten casual form of speech?
It is a casual / informal / slang version of the following:

> 訳{わけ}が分{わ}かりませんよ That doesn't make sense! / I don't get it / I don't
> understand.

The 'slang' part is changing the plain negative わからない to わかんねー. Changing the
ない part of a verb to ねー is a common usage in informal Japanese. That would
result in わからねー, but it can be further 'informalized' by changing the ら to ん
to give わかんねー. This doesn't work for all verbs as there are specific phonemic
circumstances in which it is permitted. By the way, if the setting is feudal
Japan, this might be an example of an anachronistic use of the phrase, since
the language sounds more like modern Japanese than Middle Japanese.

As for the grammar, it is a simple case of:

```

    Subject (訳), subject marker (が), verb negative (分からない), emphasis particle (よ)
    
```
