New PS2 BIOS format.

[Truth Unknown]

BIOS Dumper v2.0
[ Posted by CKemu 12:59 on 30 06 07 ]
Florin has just released BIOS Dumper v2.0 which you can grab from our Downloads>Tools Section here.

This program will dump the PS2 BIOS, DVD Player ROM, NVM etc from your PlayStation 2 via a 'host' enabled connection.

PCSX2 0.9.4 will be using the new format BIOS (*.p2b) created by BIOS Dumper v2.0, as it dumps a more "complete" copy of the BIOS. It is highly recommended that you redump your BIOS to get a more complete dump and thus enable PCSX2 to more accurately emulate the PlayStation 2

You won't need to throw away your old BIOS files, as a convertor will be released in the future to convert the older format to P2B. Conversion is no substitute for a redump as converted BIOS's will not contain the new information dumped from BIOS Dumper v2.0.

The source code for this tool will be made available shortly on sf.net. For now grab the tools here and get dumping!

EDIT: If you have downloaded before 30d 6m 2007y @ 20:11 GMT+0, or are having problems making the p2b file, please redownload the files provided, as they have been updated!

So brings my question, will pSX use this new BIOS format for the future PS2 emulation?

Makes me wonder what exactly was missing from the old, incomplete bioses.

[Truth Unknown]

Well if pSX Author plans to emulate the Network Card on the PS2, this BIOS would have that data. I think there is more, but maybe not that much.

[Gamesoul Master]

Maybe it dumps the dvd drivers, ps1 drivers, etc... Doesn't the BIOS itself only contain the commands and instructions for interacting with these?

[ssjkakaroto]

Maybe these new BIOS could be also used for PS1 emulation in pSX?
They might result in a better compatibility.

I don't think so, seeing as the real PS2's compatibility with PS1 games is not 100% (however it's a very high %, I think; I've tried many PS1 games on my PS2 over the course of two and a half years and so far only 1 failed). Sony themselves state it in the PS2's manual.

yes this is what we called gimmick, the gamecude game dvd cannot fit in your pc dvd. ps2 cannot load ps1 unless it is your D-I-Y modding it.:-)
