I just got a PS3 it's an older one with ps2 compatibility. It has multiman already installed. It looks like it boots into a custom firmware straight away as it starts with a sega logo and startup sound. I checked firmware and it says 3.66. The multiman is in the 4.xx. What should I do with this set up now. Is it worth updating? My issue is it seems to play all discs but ps2. When i load a disc it freezes on a black screen, then I have to pull the plug. I've put a DVD in and that seems to play fine as well as PS3 games.
