Mac users interested in Jpcsp emulator for snow leopard generally download:
JPCSP is an emulator for the Sony Playstation Portable. It is the first emulator for the PSP made in JAVA, which is no small accomplishment. This makes it possible for JPCSP to work on all the platforms that support Java. I don't think the Mac would have a PSP emulator if it wasn't for JPCSP.
