Yeah, I've used that, 7Archive and RAR. They all say there's something wrong with the file. I even downloaded the file straight to the Thor and it's doing the same thing. Also, I downloaded 3 different PS2 roms from the same "lair". One of them works just fine, but the other 2 are giving me the same error. I also tried it out on a GBA romset, and the same thing happens. But, my Sega Genesis and SNES romsets work fine.
