thats the source to the osk that video'ed, posting it to let developers know how the serial data stream looks like

Errrr........ what? How do we get this working? Did you have to splice a DS with a PSP, or did you order from some factory surplus type thing?

If you can get this working on a practical level (i.e. so that a large percentage of the homebrew community can do it) you will have successfully turned the homebrew scene upside down on a level that hasn't been seen since Dark Alex released popstation and Custome Firmwares. The flood of homebrew games will be reborn with touch- screen implemented things with greater hardware potential than the DS, shooters will play better (homebrew), and there will bemore plausible attempts at DS emulators (i.e. ones that have more than 6-7 fps emulation). Maybe Exophase would even make a DS emulator from the ground up that would rival gpsp!

If you can impress Sony with this without infringing on Nintendo's copyright laws, Nintendo would officially be RAPED if Sony implements this, because then the PSP would literally do EVERYTHING the DS does, but better. Better graphics, better variety (not just games, but movies, music, and internet), and better potential quality. I like the possibilities.

thank you !!, no all the electronics are custom designed, components sourced mainly from europe, when the thing is finished it will have no hint of "home-made".

Yes very astute, thats all very true, and wait till you see what it does to the pda market !!
