I have a 1st generation PSP in original set up condition and I used it for games occasionally in all that time.
I don't know how to do anything else on it. I can't even unlock WMA for song playback.
Although, I discovered a video site (I don't think it was youtube) had an option for downloading
straight to a PSP. So I brought my PSP in for a week of lunchtimes. That was fun. And easy.
I still hadn't set up internet at home at that point.
Using Yabasic on such a small medium would be good to show my work to others. My Acer aspire One is small, though.
I still remember the kick I got from showing people that programs could be written and played on their PS2.
