Various Notes:

Run>Execute upto 01.60 BIOS's will boot a game with showing the BIOS splash screen. But post 01.60 BIOS's will boot to the memcard browse screen, and if you select the disc icon it tries to boot the game, but fails, and goes back to the browse screen.

Date / Time: No matter what you do to set it, it always resets to 1999/12/31/ [random time].

Insert Disc: You can't be browsing the memcards etc, and then insert a disc into your drive, to let the PS2 detect it. This is because P.E.Op.S. won't let you boot PCSX2 without a disc in the drive.

Audio CD: No audio CD detection, thus stopping you from accessing this section of the BIOS.

DVD Video: No DVD Video disc detection.

PS1 MC: No PS1 memcard handling.

PS1 Disc: No PS1 disc detection, thus no black disc icon.

This is not a PS2 Game: Never been able to get that screen. (Normal PS2 BIOS intro screen, but all red with a warning.

White Cubes / Crystal Orbs In Intro: History DAT info, is it getting written?..can't seem to induce cubes, except with my FFX memcard, if the conditions are # of games booted, is this being written with run>CD, or would run>execute be the only method.

Call for more BIOS dumps: with the console serial (SCPH blah), and all the required files, eg; ROM0,1,2 EROM. Perhaps named like:

SCPH-70000 (Europe v01.20 02-09-2000 Console) (mod / nomod).rom0

Run>execute: Patch's are not used. (assuming you're using a 01.60 bios)

wrong, I use the US 2.00 and run -> execute shows the bios intro as normal then goes ingame , always did that for me on any build and any bios versions

The 02.00 BIOS can 'occasionaly' boot the game (with garbled PlayStation 2 logo). The Jap 01.70 / Eur 01.90 will not boot a game via Run>Execute.

Okay, so it seems [someone want to correct me here] that the 'system configuration' file saved to your memcard controls the # of white cubes you see in the BIOS intro. This # is based [afaik, again correct me here] on # of times you have played / loaded a game [different games].

Problem with this being, I can't seem to force my main bios (01.90) to write a 'system conf' file to the memcard.

Clock though wrong in the BIOS, I did by mucking around with it, learn that the crystals represent the time.

Hours represented by Crystal Selected.
Minutes represented by how full the crystal is. (Higher the # of minutes, the emptier the crystal)
Seconds represented by angle that the clock faces you.

it didn't take me too much time to realize that the crystals were the clock (the first thing I did with my ps2 was setting up the clock), but it was harder to deduce WTF where the minutes displayed

not really a BIOS bug as such, more a PCSX2 bug but...

if you run a game via Run/Execute, patches down work

just thought id add that

yeah, they don't, it's not a bug, since when we run though we actually exec the ps2 elf manually, this way we can patch it, but not if the bios loads it.
