So for your response to number 3, I can put a bunch of say, Mame games on a DVD-r, put it in the Xbox and then run the emu and have it read the games off the disk? Does it save for say RPG's? Like Final Fantasy 4 for SNES?
Well most of my Emulators save to the E:/Saves folder if im right but yeah, i have mine their. But as for your, you would have to find out through the settings see.
