Welcome to the site Fallen, I think I remember you. Well it's easy, simple answers. Emulators do not work for with the pro-c client, but if you just disable the atpro.prx and turn disable the force high memory option. I don't think you need to enable the iso cache for obvious reasons but try that too. And the sleep function doesn't work while using pro-c. You'll have to press "Home" and then hold the "Select" button for about 5 seconds or so until it exits the game. After that, you can just place your psp into sleep mode.
