Who wants a near full speed and very playable GBA emulator for the Sharp Roms. Suhami(is that his name?) compiled the original gpsp for pdaxrom and I ported it to the sharp rom (http://www.suhami.net/ez/?page_id=7).
It needed a compiler upgrade, the 2.95 gcc is not up to the task of compiling anything anymore.
Gpsp since it is made for the psp and then ported to gp2x has very good arm assembly optimisation for near full speed play. I have tried many games and most of them are very playable.
I am including the executable in this post as well as the script needed to play it in zemu frontend. I have modified Suhami's code to change the key bindings to
(L,R,Down,Up,Left,Right,Start,Select,B,A) => (SDLK_a,SDLK_s,SDLK_DOWN,SDLK_UP,SDLK_LEFT,SDLK_RIGHT,SDLK_q,SDLK_w,SDLK_z,SDLK_
If you dont like these keys suhami aslo mentions in his website and i checked his code that you can use the environment variable GPSPKEYS as shown below to use your favorite keys.
$ export GPSPKEYS=303,120,274,273,276,275,13,32,306,308
I am sorry not to ipk it but maybe someone can do it for me... and oh yes you need libsdl for it.
