Multi-disc (games with more than one disc) backups/imports require a procedure to change from disc to disc when using a game enhancer to play them. Although the methods work fine, they are somewhat complicated as opposed to just opening the tray and putting in the next disc in the set. While it's rather simple to play multi-disc backup/import games that feature a save option at the end of each disc (like Final Fantasy 7 and 8) or games that allow you to start with/play any disc of the set (like Gran Turismo 2), It is more complicated to play multi-disc backup/import games that DO NOT have any of these features, and involves acproper timing and technique to get it just right
