I have a lot of familiarity with GBA's assembly language and decent knowledge of its specs, so I might get some decent headway into the ROM depending on how "in-house" the programming is. I've also reverse engineered GBA/NDS compressions algorithms in python so I can also produce a low spec (read: command line) decompressor.
I can also locate other data like level data although that will likely take more effort and require understanding of the original programming (which is doable, just a pain in the ass. ) Without knowing anything about the game, though, I can't guarantee how much I'll be able to follow through, but at the very least I can probably get some meaningful stuff out.
