I started out playing around with the Fenix source code for a GP2X/32x game called Istappen (source posted at http://fenixonfire.gp32x.de/html/sources.html), testing some music, sound, and graphics loading code as a way to test the limits of Fenix on Dreamcast, and ended up adding more and more features to the code. It's now to the point where it's become a full-fledged, albeit unfinished, game of its own. The original game has the player dodging icicles and grabbing packages as they fall. One hit and you're dead; game over. I've added music (excerpts of my own ambient compositions), sounds, new background and mode7 graphics, other new graphics (all placeholders at the moment), a player energy routine, powerups (energy and lasers only at the moment), a routine to count chains, and some other code cleanups. It's become quite a fun and addicting game in its own right so far, but I've got a lot to add and a lot of work to do to bring it up to my own high standards for a completely fun game. Once it's finished, I'll be releasing it with full source code so that others may learn from my experience. Here's a screenshot of the current WIP:
The game is being written primarily for the Dreamcast, but it should be able to run on any of the Gamepark consoles when it's finished (although I don't know the limits of the GP handhelds; I don't own one). I've got a lot to add to it; levels, more enemies, some bonus features, Quiest and Moogle's sprite fonts code, better graphics, more powerups, and other features that'll make it a simple, yet full-featured game similar to the ones I played in the 80s in the arcades.

Good luck anyhow!
