Xenia module with XBLA support 
Feel free to lift and shift in to other versions of this module.
This works by looping through the files in the game / extracted directory looking for a file without an extension. If it finds one, it attempts to launch as a XBLA game. This should work well, though might not work if your Xbox 360 main games are extracted (as there could also be files without extensions there too, I haven't checked). Should work perfectly fine if you use iso for 360 and the dumps of the XBLA games (provided they don't have DLC in the same zip).
