Can this game be revived?


I found this poor copy of Hamtaro Ham Ham Heartbreak that looks like it met with a flood. I've cleaned it up a bit already, a lot of pcb had flaked off and there was quite a bit more rust and corrosion on it. The way it's looking now, despite my best efforts, I don't think it can be saved. Any suggestions? Should I just find a game with a similar board that I can cannibalize and drop the chips in that? I'd prefer not to have to destroy a game to save one, if that's possible. Are blank GBA homebrew boards a thing yet?
Many thanks for the help
