According to the guys at ps3news there is a download and pics for the first rom emulator for the ps3
Jurai has released an AdvanceMAME .106 PS3 Binary today. To put it in layman's terms, it's the building blocks for MAME usage on your PS3. AdvanceMame .106 PS3 Binary is basically the emulation code you'd need to use on the Linux in your PS3 to run arcade games, minus any ROMS. Under normal circumstances, MAME executables can have download sizes as large as a few hundred MB because of the number of ROMS they include with the downloadable file. This makes it a whole lot more manageable to download, but it also means that newbies to codes and binaries and other techie terms need not apply.
