PS1 game lists in PS2 BIOS

[Deterous]

I've attached a zip of a list of serials for each BIOS. It would be useful for knowing which consoles supports which game in terms of backwards compatibility, etc.

With the new BIOS dat out recently, (115) (2022-12-12), I thought I'd just update this post that there are no new serials mentioned:

ps2-0170jd-20030206 lists the same serials as ps2-0170j-20030206
ps2-0190ad-20030623 lists the same serials as ps2-0190a-20030623
ps2-0190k-20030623 lists the same serials as ps2-0190h-20030623
ps2-0200ed-20040614 lists the same serials as ps2-0200e-20040614
ps2-0220jd-20050620 lists the same serials as ps2-0220j-20050620
ps2-0220jd-20060905 lists the same serials as ps2-0220j-20060905

All right, I finally spent some time for this, and identified some

PSX Europe:
SLES-00977 - Resident Evil - Director's Cut - Bonus Disc (https://github.com/libretro/libretro-da … /ps1.idlst)
SLES-10977 - 2CD???

SLES-01227 - 2CD???
SLES-11227 - 2CD???

SLES-01894 - ???

PSX Japan:
SLPM-80639 - 2大ヒーロー スペシャルDisc 体験版 [2 Big Hero Special Disc Trial Version] (https://w.atwiki.jp/psemu/pages/124.html)
SLPS-00653

More research:

Resident Evil 2 (English)
SLES-00972
SLES-10972

Resident Evil 2 (French)
SLES-00973
SLES-10973

Resident Evil 2 (German)
SLES-00974
SLES-10974

Resident Evil 2 (Italian)
SLES-00975
SLES-10975

Resident Evil 2 (Spanish)
SLES-00976
SLES-10976

Resident Evil 2 (XXX)
SLES-00977
SLES-10977

Looks like we miss Resident Evil 2 dump of unknown European country.

00977 number is claimed by the bonus disc, so it seems very unlikely that an unknown RE2 release exists with the same number.

It's marked as such in emulator databases, but doubt it's accurate.
Also second disc serial follows this exact pattern from the other regions.

SLES-01227
SLES-11227

It can be Command & Conquer: Red Alert or
Command & Conquer: Red Alert: Retaliation

The only 2CD game regional releases of which were scattered around the same time frame.

Current best guesses for RE2:
- Special Edition (Germany) release - Claimed to match normal German release, but need pictures for proof
- Ireland - Resident Evil 3 has an Irish release with a blue rating logo on the box

Is the order of serials untouched in these files? I wonder if we can deduce some information based on the serials initial ordering e.g. if these were grouped based on some criteria in the firmware.

Sorry, the forum is bad at letting me know when there are replies.

The orders should be untouched yes, I just used the strings/grep commands and piped them out into a text file, so they're in byte order.
