You can also look at the host of Linux projects for various PDA's. Most of the source code are great fun(in a sadistic sense) to read. Wing.

It very much depends on the device and how "open" it is. I think it is quite easy for PDAs, more complicated for PSP. >Also, where is information on these devices (technical docs) and how to Google. >program them? (I'm just a hobbyist, not a big software company of any >kind). Gameing handhelds which are easy(1) to program (even with simulators on PC) that come to mind: Atari Lynx, GP32, Gameboy (various), Sega GameGear. (1) "easy" in the sense of "you get a lot of information". For some of these you need to have some experience writing assembler :-) -- 42Bastian Do not email to bastian42(a)yahoo.com, it's a spam-only account :-) Use <same-name>@monlynx.de instead !

I'm still toying with getting one of these myself. I do like a retro game and Mario Kart on SNES is gameplay perfection - no-one has ever made a better game IMHO. However, Nokia bring out the N80 next month and that looks like fun to play with as well. Not so much for the gameplay but using the wi-fi to get TV progs I've stored on my PVR to watch on the phone on the train is going to be great.
