From what I can tell, you need to rip the discs separately. From there you play until it tells you to change discs, and then you copy/paste the save file from the disc 1 folder into the save file folder for disc 2. I haven't tried this myself, and have only just got the tool working, but from what I've read on the xda forums this should work with Final Fantasy VII-esque games. Such as where it simply uses the existing save and allows you to load it directly from disc 2. Let me know if it works so I know (Off-topic: Have you rooted by the way?)
Thank you, i will let you know if i get that far on a game to change disc, yes i have rooted using superoneclick due to low internal memory, now i can move apps over to sd without worrying about space, i was thinking of going to gin2jellybean rom but im worried i will brick my phone as i have never done that, taking things slowly and picking things up till i know abit more about stuff.
