I have the WiiSX emulator and I have PS1 ROMS for it. When I try to load them, it doesn't work. The ROMS i have for it are RAR files. Do they have to a different file type in order for them to work? When I try to load them, the emulator will pick them out for me and ask me if I want to load them. It writes a few things on the screen and stops. Any tips?
