My physical discs are too scratched unfortunately. I obtained "backup" copies of Disc1 and Disc2 in CHD format. Converted them to BIN/CUE using CHDMAN, then tried using ISOBUSTER to convert Disc1 into an ISO following your readme and got an error. When I checked the Track01 contents it looks like there's an issue with "CDDA1" (red "X" next to it). This is all a bit high-level for me to wrap my head around so I think I'll call it a night and try again tomorrow (unless you have any tips on how to convert CHD straight to ISO, or would be willing to PM me your copy?)
