For anyone who has NesterJ, I've been having very good luck with the newest version on my PSP Slim. However, a friend and I want to start a 2 player game on Mario 3. She doesn't have a PSP, so we were just gonna switch off like the old days. Is there an option to switch the controller inputs? Because every time Luigi comes up, the buttons cease to operate. I know in the Super NES emulator there's an option, but I can't find it here.

Any help is appreciated!!
