hrrrrrm..... for starters its gotta be chichrox, it is infact a emulator as it has several built in, and its the closest looking thing we have to a profesinal gui, skin it your self and its even more amazing than before. i would have added xbmp but thats not a emu. close 2nd is all of hikarus other emulators, they are very profesional and hard to beat from that standpoint, and thats what i look for is a pro look and feel and he has it. a close 3rd would be xport and the psx port. He also did a good job.
