I never got that far, but my goal was always to give it a shot. All of the ARM instructions used in this emulator are supported on that CPU. You'd have to implement interface adapters specific for the GBA hardware, but I structured the project such that you shouldn't need to untangle anything.

That’s awesome. Hopefully someone maybe picks it up because goomba is kind of terrible and weird :)
