I've never been able to get regular Mame to run, so i've always used Mame32.
They have a stand alone cps3 emulator, that's the one I was trying to get running. Unless the new Mame32 supports cps3.
The ONLY problem I had once I updated it. Is alot of my working roms, no longer worked, so I just kept the older version of Mame32, because all the games I liked ran. Unless it's a matter of downloading a NEWER version of the rom, which if I had a website I could actually get that data from. I'd be more than happy to update everything.
Please let me know.
