Wats up man I read that other post u linked and listen to the guys there because they're right. The TData and UData have nothing to do with x-port emulators. The Udata that is stored on the E drive is for Xbox game saves, default thumbnail pictures, etc. The TData that is also stored on the E drive is for any emulator that isn't ran by x-port. This could be savestates on the surreal64, configurations set up for other emulators, also are programs such as Mimesis, X-DSL, and all those third party homebrew programs that you can install from Auto Installer Deluxe. All X-port saves are under E:/Saves/Any x-port emulator. I will get the ISO and try it myself and I'll tell you the results.
