Here is LBreakoutHD, an opensource remake of the arkanoid clone LBreakout2, but with HD / Widescreen capabilities.
The game use gl4es to run, and should run on all Pandora model.
Here is SDL-Ball, an opensource clone of DX-Ball / Megaball
This one use glshim, and the Batch mode of it to provide decent framerate. Still, with the EyesCandy on, when a lot of brick explode it can be slow.
I advise to turn EyeCandies OFF on CC model (and may be also on Rebirth model).
