Didn't work. When I did that and tried to put it on the HDD, it told me that it was not a valid PS2 disc. And yes, I used the swap method with the changed/burned copy.
I took the info(thanks, by the way) and did some experimenting. Tried rebuilding, renaming, reorganizing, replacing and deleting......all to no avail
Guess I'll have to stick to the disk for UMK3 until I figure something out.
