The .cue parser only extracted the FILE line and the CD model hardcoded a
single data track: GetTN always returned 01..01 and GetTD returned LBA 0 for
any track. Multi-track discs with a CD-DA audio track (Tomba 2: TRACK 02 AUDIO
@ 38:48:74) therefore reported a bogus TOC.
- iso_reader: parse TRACK/INDEX lines into a CDTrack table; synthesize a single
data track for bare .bin/.iso. New TrackCount/TrackStartLBA/TrackIsAudio +
iso_track_* C wrappers.
- cdrom.c GetTN returns first=1/last=track_count (BCD); GetTD returns each
track's real start MSF (lead-out via 0xAA/track 0 unchanged).
Framework fix for every CD-DA title. NOTE: does not by itself unblock Tomba 2's
boot — that still stalls in a GetStat/GetID/Init disc-init loop (display toggles,
reading=0) which does NOT call GetTN/GetTD; next is an oracle CD command/response
diff at that loop (and the hardcoded GetID region "SCEI" vs USA "SCEA" is a
candidate). cdrom_trace_dump floods with DMA 'D' events — fix that (Rule 15)
before the diff.
