I tried the files you posted: no luck. I am inserting the disc when trying (though i tried both ways, too) The farthest i seem to get is with street fighter. it says it needs to update but the update fails. trying to play my original backup (sega) leads to a black screen.
Quick update: I disabled network connections and tried to load SF. i got to the point of it saying there is no saved data, would u like to start. yes and no are available but it wont let me move the bar to chose. idk if it help but atleast that kinda loads.
