I agree with the GUI for all GX emulators, they work and feel perfect. It's a shame that the GX emulators can't be updated to have all the new features the retroarch emulators now have, i have tested the FCEUmm Libretro (r0.2 MOD) recently, it feels better because of the speed and extra features/plugins like 2xSaI, but the retroarch GUI is a mess. isn't it a good idea to completelly remove the GBA features from VBA GX? Because mGBA is far more superior.
