If you are looking for a multi engine emulator to play some games then RetroArch is something to check out. RetroArch version 0.9.7 has been released and supports NeoGeo, NES, SNES and Game Boy Advance consoles.
This is the PS3 CFW version but you can also grab the DEX version at the source. Here are the release notes for the PS3 CFW.
"Put the PKG file 'retroarch-ps3-v0.9.7-cfw.pkg' on your
USB stick. Put it in your CFW PS3. Go to the PS3 XMB - go to the
Game tab - select 'Install Packages', and install the PKG file.
NOTE: The official release no longer supports Geohot/Wutangzra
CFWs. If you must use them, you have to do pkg_finalize on the PKG
to install it.
More info in the readme."
