Would it be possible to utilize some of the code from the GP32 scene? http://gp32x.com is a good site to get all the source code for most of the emulators. The Gamepark 32 is a korean handheld that is totally opensource, I have one that I sometimes use as a jukebox (light and 'A' button dont work). It is a really nice system, I think the CPU is only 200mhz, and 8mbs of ram, but most emu's run at full speed so this could give some dev'rs for the PSP a headstart. Sorry if this is just totally ridiculus, just brainstorming....hoping that by the time I get a PSP, there will be some pretty nice homebrew stuff running decent.
