As promised, I made a zip package with fpc4gba binaries. In the package I have added a library (it works, but it needs some test) and a couple of examples. Speed is very improved from the last time, and now smartlinking works fine too.
You can find the package on my web page :mrgreen:
BTW, now I'm investigating about the possibility to port fpc for nintendo ds too so, as for fpc4gba, any help is appreciated

To all SDL users: I have found a sdl porting for gba, so it could be interesting if someone would try to mix sdl for freepascal with it
