Let me first thank everyone here, you've made a great forum. I have read conflicting posts and tutorials about which file type to use when burning, the ISO or the MDS. I have attempted to burn the ISO several times and it has never worked with my Swap Magic discs. The ISO has a winrar icon to it, but it appears to just be a regular ISO. I see in one of the tutorials in this forum that mentions using the MDS file but that file is so small, can this possibly have the info for the game? The only game I've attempted to back up so far is Tony Hawk's Project 8. I am using swap magic 3.6 with a flip top case. One disc I burned gave me an error when swapping saying it was not a valid disc, the other gave me an all black screen with some scanning type sounds but it never actually loaded anything.
