Thanks everyone, especially fDave (for Cyclone... still affecting us all years after developed), Notaz (Picodrive, Cyclone fixes), Reesy (DrMd), Squidge (SquidgeSnes), and whoever did the NGPC emu (apologies, I can't remember who created that one). Plus Zodttd (godlike dev person of Psx4GP2x and GPSP fame, let alone TTD; I'm sure you all know him) and the guys who made GhostPix, which whenever I actually get onto the GP2x these days seems to eat my time!
And of course Rlyeh (minimal library) and Ryo (such a lovely interface)
And everyone else, of course, who I've missed off! You make this handheld live!
