I've just compiled GP2X version of gpSP, it has all fixes from Wiz version + software scaler as a bonus. The later causes more noticeable performance hit then on Wiz, but is still usable for some games with some overclock. I've also bundled it with RAM timings setting app, I don't think everyone was setting their RAM timings manually.

I'm interested how much emu oriented GP2X users we still have, if you are going to use this please post in this thread.
Still using mine - another great update for my trusty gp2x!
