So, I'm trying to hack a game other than Brawl. Just a texture hack. But whenever I try to save the .brres, BrawlBox won't save it because the model doesn't have the model fixes needed.
So I can't save it.

Is there any way around this?
Also, do FPK compressors exist? I'm trying to hack Naruto GNT SP, which reads data from FPK files. So is there a way to compress to an FPK file, or just edit the files inside of an FPK file?
