Thank you.
I'm happy to see that the work I've done is appreciated by someone. DCelso's port was actually better than mine. I think I will do some upgrade on this code and generate one, better, improved, merged version. PSP deserves BennuGD. Side note: I didn't have such a nice emulator like PPSSPP to test when I wrote this code. It was pretty much a pain to setup some link between PC and PSP and try to debug this code.
I'm Daniel Franzini by the way and I'm still around. I just don't have as much time as I'd like to work in these cool things.
Did you tested on the real hardware? I can do this quickly for you to see if it works like in the emulator.
