So, I'm interested in emulating SNES, Genesis/Mega Drive, Sony PlayStation, GB/GBC/GBA, N64, and possibly DS if it will run, on my newly acquired Android phone. I have never had an android before, and so am quite excited at the already obvious capabilities of the OS. I've already got a GBA, GB/GBC, SNES, and PSX emulator on it (I have not tested the SNES EMU yet), and I got the GBA, PSX, and SNES EMUs from here, but I was wondering what the absolute best free emulators out there are. I am interested in being able to use save states, if at all possible, but they are not an absolute must. What do you guys recommend?

P.S. Is this thread okay in this category?
