兄貴は夢を叶えたんじゃない

Which I think it's like "My brother didn't fulfill his wish"

What difference is from 兄貴は夢を叶えなかった

?

Edit the whole sentence is:

お兄さんは"夢"を"約束"に変えてくれた. 兄貴は夢を叶えたんじゃない. 約束を守ってくれたんだ!

question
negation
Past verb + んじゃない what is his function?
兄貴は夢を叶えたんじゃない (in this context) means _it is not that my brother made the
dream come true / my brother not only made the dream come true_.

兄貴は夢を叶えなかった means simply _my brother did not make the dream come true_.

The speaker is saying that the brother made something happen and it wasn't a
dream but a promise. んじゃない（のではない） negates the clause as whole whereas a simple
negation negates the verb (叶える) and means it did not happen.

I think it is similar to English _it's not that A_ and the simple negation of
A. ( _It's not that he did something wrong_ is not the same as _he did nothing
wrong_ in a nuanced manner, perhaps depending on contexts.)
