Well I use the Game Info plugin in conjunction with GameExtender and it's pretty cool. I developed it to do lots of things, it integrates your jukebox with Last.FM, adds Hi-Score comp functionality to MAME, can show a CP for a system or game, shows play times and game bios, manufacturer info, and can display whatever artwork you like in game if you have a folder set up in the Game Extender artwork path for the emulator. It's also fully skinnable to match your theme. /end shameless plug
