This is a build of SDL MAME 111u4 & related libraries for the Sony PlayStation 3. The PS3 sixaxis joypad works (albeit crazily sometimes; needs some improvement). Also included is a front-end (psmallphront). Its got video & sound working on a self-contained, bootable linux .iso that boots up & runs one game- robby the roto (video boots into 480p, btw).
Copy to /PS3/OTHEROS/ on a memory stick, CD-R etc, with the $ony otheros.self, and run "Install Other OS" from Settings > System Settings of the XMB. Then set default boot to OtherOS, reboot, and it will run!

The otheros.bld gets installed to the PS3, and the cdr-test.iso can be burned or mounted as that is where it boots data from.
