I've never tried this, but it might've worked. it might just be showing disc 1, since it doesn't know which disc your save is on until you access it. is the save on disc 2? what happens when you access it? this is sorta like how I have my 360 setup. I have all discs but disc 1 of games hidden. even though I'm loading up disc 1, the system will know to swap discs for my save. it's fool proof from what I've seen too.

another possibility is a hidden menu for swapping discs. I've been delving into the psx classic recently, and in the instructions, it says that the open button is for swapping discs, not physically opening the system. maybe it's a menu that you have to access. if you can't figure it out, try looking for an official game that's been released that's two discs and compare.[/QUOTE
I don't have any save for the game. I would like to find one and test this.
