Here you can find some software that I've made. I make software all the time, either for myself or as part of my work, and some of it turns out to be useful or is purely for entertainment so if others can benefit from it, it's worth distributing.
STPPC2x is a port / conversion of Simon Tatham's Portable Puzzle Collection for the GP2X (and other) handhelds.
I'm also currently working on my first closed-source project, the mysterious Project X, which I will reveal when I have something worth revealing. It is a game, and it's nothing too ground-breaking, but it's something I've been meaning to write for the best part of two decades now. It currently stands at over 19,000 lines of C code that I've written (so not including libraries, graphics, sound, data etc. that I use) and uses SDL as the main library.
