Here's the most recent build of PSPGBA, entitled 'PSP GBA v1.2'.
- Slightly faster emulation
- Fixed up the menu a bit
- State saves/loads
- Vsync, Frame skip, sound on/off, screen size(smoothing)
- ZIP support
This emulator offers pretty much all the basics.
I'm not sure whether or not I will continue working on this. I've already done a ton of optimizations and various other things. Source included for anyone wanting to tackle the project.
Big thanks to psp298 and Miemt11, for the original GBA 1.0 and 1.1. Also a big thanks to Cools for helping me initially build it.
EDIT - 2.0+ doesn't seem to be working.
