Hey the emu has the clock settings built in. I'm talking about opensnes9x not snes9x which is worse, just download version 2 and than you can choose clock settings when you start the emu. Make sure to try a clock setting for a few minutes to see if its stable and than just keep going higher until it locks up or crashes. And I misread your post and made a useless one lol :lol:
