how the flaming homo can you make games for GBA?
With a GBA compiler. There's a GCC port for the GBA, a bunch of other C compilers, various assemblers, and even a couple of BASICs (like DragonBasic, which I've used and it works pretty durn good. I've written a few things for the GBA but without a linker (and a GBA as well), I can't try them out on real hardware, only on emulators.
Talking about GBA.... anyone has some suggestions for a good GBA-emulator that runs under XP? And that is compatible with alot of cool roms?
Just player both on emulator
Tetris = cool, got to 41 (then they started moving to fast)
Asteroids = no end condition?
EDIT: I think VisualBoyAdvance works under WinXP. It's run everything I've thrown at it so far

Yeah, visualboyadvance is the best one.
Btw, wouldn't it be great to have a port of fB for GBA?
That would be interesting, although DragonBasic is very QB-like and does a great job.
Hey, is it possible to get a machine that programs Gameboy cartridges so you can actually publish your games?
Probably - you may also want to ask nintendo about developing games for the GBA - seeing also all gameboy software is mean't to be liscensedby them.
