PlayStation 2 - BIOS soundtrack [PS2 BGM Rip]

Ambient sounds from the PS2 BIOS. Short sound effects (less than 5 seconds) are not included here.

These sounds seem to be using the SShd/SSsq sound format (used by some first-party Sony PS1/PS2 games as well)

The HD/BD/SQ files are embedded directly inside the BIOS ROM (in compressed form). I have actually managed to partially convert these into a soundfont and MIDI files, you can listen to an example here, but I couldn't convert accurate ADSR yet, so it doesn't sound exactly the same: http://paktc.markusmaal.ee/redscreen.zip

However, in this video, I have instead opted to trick the PlayStation 2 into playing these sounds, which was easier to pull off and it is 100% accurate.

Chapters:
0:00 Startup sound
0:18 Startup woosh (played immediately after startup sound when no disc is inserted)
0:27 Main menu ambiance (played on the main menu/system configuration screens)
5:27 Unknown (maybe a part of another sound?)
5:33 Short woosh (played after startup sound when a game disc is inserted)
5:39 Red screen of death (plays when you insert an invalid disc)
10:40 RSOD variant (might be an unused sound?)

P.S. If you are the first person who can figure out the exact time of day I recorded this based on the flying orbs, I'll pin your comment.
