<![CDATA[Redump Forum — PS1 game lists in PS2 BIOS]]> http://forum.redump.org/topic/46073/ps1-game-lists-in-ps2-bios/ Fri, 30 Jan 2026 06:16:34 +0000 PunBB 1.4.4 <![CDATA[Re: PS1 game lists in PS2 BIOS]]> http://forum.redump.org/post/135652/#p135652 Update:

I spotted SLPS-00653 serial in a store-only promo disc (MiruMiru), it belongs to an probably unreleased PS port of Father Christmas (SS game).

SLPM 80639 is also now dumped: http://redump.org/disc/130756/

SLES-01894 remains a mystery, but it is located in the BIOS next to other regional variants of Player Manager 99, so there's a chance some other region exists or was planned (English/German/Italian/French/UK/Portugal are dumped, Greek and Dutch match English).

That just leaves the SLES serials that were probably allocated to Resident Evil, and may have been cancelled or internal/beta discs as there's no evidence that an undumped regional variant exists:
SLES-00977 (Disc 1)
SLES-10977 (Disc 2)
SLES-01227 (Disc 1)
SLES-11227 (Disc 2)

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.

- 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

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.

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.

I've trawled through all known PS2 BIOS's and found a total of 784 mentioned serials, approximately 567 of which are PS1 and the remainder PS2. A few of the serials are not dumped and have unknown titles.

This is nice, thanks for doing that!
I'll try to check what's there a little bit later.
