Mupen64 I always thought of as the emulator with the strongest core, focused on accurate emulation more than on other user entertainment forms like GameShark cheats and other features.
It is the only major emulator that does not support GameShark cheats.
Also, I just wanted to take the time to show off this new graphic I just finished before I opened this thread. It's not sold in any stores; NOW how much will you pay No.
