Well, yeah... it has more functions, but that doesn't say anything about accuracydoes that answer your question??
I remember that no Android emu could correctly play Shin Megami Tensei 1's fusion animation, then came SNES9x EX by the .emu's author and well, that did the trick, and I'm sure that all the others out there probably still don't play it correctly.
That's why I held in high esteem the .emu emulators, I'm sure they strive for accuracy more than others.
QFT. ePSXe is a no-hassle emulator. It just works, and it's faster than FPSE.for PSOne ePSXe is the answer, much better than FPSe
