...after a lot of new PC dumps and sub checks it's clear the last version of PR has a bug on gaps detection: it finds a lot of INDEX>1 on single data tracks CDs and sometimes also on audio tracks, the weird issue is that those INDEX are also double or out of order. An example on last dump:
FILE "01.- Treasure Island (J).track.img" BINARY
TRACK 01 MODE1/2352
INDEX 11 11:07:42
INDEX 01 00:00:00
INDEX 11 12:57:22
INDEX 01 12:57:23
FILE "02.- Treasure Island (J).track.pcm" BINARY
TRACK 02 AUDIO
INDEX 00 00:00:00
INDEX 01 00:02:00
FILE "03.- Treasure Island (J).track.pcm" BINARY
TRACK 03 AUDIO
INDEX 00 00:00:00
INDEX 01 00:02:00
INDEX 21 00:21:62
INDEX 01 00:21:63
FILE "04.- Treasure Island (J).track.pcm" BINARY
TRACK 04 AUDIO
INDEX 00 00:00:00
INDEX 01 00:02:00
FILE "05.- Treasure Island (J).track.pcm" BINARY
TRACK 05 AUDIO
INDEX 00 00:00:00
INDEX 01 00:02:00
FILE "06.- Treasure Island (J).track.pcm" BINARY
TRACK 06 AUDIO
INDEX 00 00:00:00
INDEX 01 00:02:00
