I don’t use PS3 RA version but I think the latest stable version which was released some time ago already have “latest” snes9x included. Have you already tried it? (Unless buildbot doesn’t include the latest cores versions for PS3, of couse)
I tried with the latest RA and the Far East of Eden game (which is a SPC7110 game) doesnt work…
I hope the Retroarch team can update the Snes9x 2010 in the upcoming 1.7.0 Ps3 release.
