I'll be sticking to the original emulators used for now. So far I've had several crashes, many games aren't detected, and control configuration has layout errors/doesn't work (keyboard controls don't respond in game). Furthermore many features in the original emulators are not present - rewind and fast forward, quick save/quick load keyboard bindings.

I really appreciate the effort but for now the drawbacks far outweigh the advantages (mainly a nice library interface). I've checked in on OpenEmu over the years and hope to use it in the future.
