Or do they have to be extracted. If they can, which emulators CAN'T read RAR'd files?
It's on an emulator by emulator basis. From what I remember, all the most popular emulators on Xbox support Zip files but very few support the RAR format. Just check the readme's for each one if you have to use RAR. Otherwise, I'd suggest just switching over to Zip.
