gpSP2X is an official GP2X port of gpSP, a GBA emulator written from scratch by Exophase. But it’s more than just a port, as zodttd has tweaked it specifically for the GP2X with features such as overclocking the CPU, RAM, and LCD tweaks.

New in this release:
– Fixed a large compatibility issue with the dynarec. Many more games working and working better.
– Removed the need for gpsp.cfg during installation. It’s now created with the correct defaults.
– Hopefully a better autoframeskip.
