That one isn't documented in MESS, so would be nice if you could provide some info or the actual BIOS file. TIA

Time flies.... 18/05/2006 21:48 446ec5b2 --w- scph5903.bin

I dumped it years ago. I'll get a dump of the CD controller firmware at some point.

You can't use it to add VCD to other models, because there is additional hardware in the SCPH-5903 that other models don't have (similar to how the parallel port VCD players have extra processors). It's possible the additional hardware has it's own software that needs dumping, which is going to be much harder.

Firmware from a memory card and all the different game controllers are much more interesting to get dumped right now.

If you can upload it would be nice for the collection.

better late than never.

What BIOS was this dumped from?

Found some "Check VideoCD" string inside.

PS-X Realtime Kernel Ver.2.5
Copyright 1993,1994 (C) Sony Computer Entertainment Inc.

PS-X ROM monitor Ver.2.3
Copyright 1993,1994 (C) Sony Computer Entertainment Inc.

BOOTSTRAP LOADER Type C Ver 2.1 03-JUL-1994

Must be SCPH-5903 I guess.

Also, note is 1MB, not 512KB.

@ 0x80000 (until the end) lies the VideoCD BIOS.

I compared the 1st part (512KB) with ps-22j and found just 5 different bytes:

Comparing files 5903.bin and PS-22J.BIN
00000000: 14 13
00006FFC: C8 C1
00007000: 04 06
00007005: DF 7F
00007009: 00 80

ps-40j.bin is the only one with "14" @ 0x00000000

I better wait for a reply from smf to confirm whether it is from a 5903 or not...

Yes, it's SCPH-5903. The (re-)naming is really confusing. If you check the above posts...
smf originally called it scph5903.bin with CRC32 specified as 446ec5b2.
then smf renamed it to ps-22(c) and uploaded it, with same CRC32 as above.
and then gradius renamed it to 5903.bin and compared it to ps-22j.bin (=the SCPH-5000 bios).
I would be tempted to rename it, too. To ps-22v.bin or ps-22vcd.rom maybe.

It was ps-22j(v).bin when I uploaded it, in ps-22j(v).zip. It reports itself as 2.2j, so that makes the most sense as the base name. I named it like the bios found in the SCPH-7000W, ps-41a(w).bin. Which is different from the American 4.1 and not a Japanese bios like you'd expect. I might have come up with that name too though, so I might only be consistent with myself.

I'd prefer an official sony naming like the cd mcu, but without that then IMO the mess/redump naming system is the best compromise. Naming them SCPH*.bin doesn't make a whole load of sense anyway.

I renamed to 5903.bin just for test purposes.

Thanks. Added

Shadow, you forgot to add the SCPH-5903, too!

And, what you have listed as SCPH-102A (v4.4e) and SCPH-102B (v4.5e) bioses are actually two different SCPH-102 bios revisions. I have two SCPH-102's, and they do have the v4.5e bios (ie. what you've called SCPH-102B).

I don't think that anybody has ever dumped the bios from SCPH-102A, -102B, or -102C models (it might turn out that they use the same bios version(s) as SCPH-102 though).

AFAIK they were just different SKU for different countries, probably power cable.

English
https://www.playstation.com/manual/pdf/SCPH-102B.pdf

FR/ES/DE/IT/NL/PT
https://www.playstation.com/manual/pdf/SCPH-102C.pdf

Different SKU for the RFU and LCD were also produced with the same suffix.

That are the "SCPH-102 A", "SCPH-102 B" and "SCPH-102 C" manuals. With a space between 102 and trailing letter.
But I don't think that those manual names are related to the console names.

European PSone consoles are usually labeled SCPH-102.

But there are also some badged SCPH-102C (and maybe SCPH-102A and SCPH-102B, too). So far, I've only seen them on photos (like the http://i.ifreeads.ru/2013/08/19/125880/ ... 5223_2.jpg one posted earlier in this thread), and also found old posts from people complaining that their modchips won't work with those newer cost-down model).
Anyways, up now nobody showed up owning one of that models for real, so they must be extremly rare (or people are just not reading their model PSone numbers) (or a mixup of both, rare and not looking very closely).

AFAICT A=Australia, B=Britain, C=Continental Europe

I'm not convinced that SCPH-102C on the label indicates anything other than it was one destined for the continent. According to one site all the motherboards are marked with the A/B/C code, it's been a few years since I opened one up though.

There are two different psone motherboards (PM41/PM41(2)) and nobody seems to refer to the later motherboard as a different model number. A newzealand modchip site refers to SCPH102A old and new version based on whether it has PM41/PM41(2). http://www.fatcat.co.nz/psx/ps1.html

There are old and new motherboards used in Japan and America as well and there doesn't seem to be any SCPH-100C/SCPH-101C rumours. My guess is one factory or some late batches just had the country code on and they are rare online just because of the people who bought them. Similar to how the SCPH-103 is hard to find (although Wikipedia now claims that is v4.6 but has an unknown date).

I don't know which motherboards I have.

smf wrote:AFAICT A=Australia, B=Britain, C=Continental Europe

For manuals, A and B are both english, and they differ only by the packaging list (with/without TV modulator). In so far, they don't seem to be related specifically to Australia and Britain. Or, did Australia always had the PSX and PSone bundled with TV modulator? Shadow, do you know more about what was bundled in australia?

smf wrote:There are two different psone motherboards (PM41/PM41(2))

Yes, that's actually what I am after: Locating consoles with those mystic PM41(2) motherboards.

smf wrote:My guess is one factory or some late batches just had the country code on

My guess would be C for "cost-down", or for "revision C". But even if it does mean "late batch": It would be a good indicator that the console should contain a PM41(2) board, right?

The other indicator would be the uncommon small plastic feet seen on the above SCPH-102C photo, which are definetly some cost-down variant. Would be interesting if such small feet have been also used in asia/us/japan. And if yes, if that consoles did have stickers with "C" suffix, too.

Shadow, you got the idea why A/B/C are confusing in rom-images names? Those letters could already mean everything from pal-sub-regions, user-manuals, video-modulators, scene-slang, to hardware-revisions. It doesn't seem right to further abuse the letters for bios-revisions (unless the bios was dumped from a console that was explicetly badged with that letter). The other issue is that we are having two SCPH-102 dumps, whilst you are still listing SCPH-102 as undumped.

This is from the SCPH-9000 service manual - and I doubt that Sony changed their numbering scheme:

Top level assembly for the console itself:

So 9002A, 9002B and 9002C are the same P/N, and hence are the same unit

CONSOLE A-6788-646-A OVERALL ASSY, MAIN (9000)
CONSOLE A-6788-647-A OVERALL ASSY, MAIN (9002A/9002B/9002C)
CONSOLE A-6788-648-A OVERALL ASSY, MAIN (9001)
CONSOLE A-6788-649-A OVERALL ASSY, MAIN (9003)

All versions have different power cords

AC 1-769-322-11 CORD, POWER 2P (9000)
AC 1-790-107-22 CORD, POWER (9001)
AC 1-575-131-11 CORD, POWER (9002C)
AC 1-751-673-21 CORD, AC POWER (9002B)
AC 1-696-819-21 CORD, AC POWER (9002A)
AC 1-777-806-11 CORD, POWER (9003)

All versions also have different cartons:

CARTON 3-987-032-21 INDIVIUAL CARTON (9000)
CARTON 3-987-178-61 INDIVIUAL CARTON (9001)
CARTON 3-050-234-61 INDIVIUAL CARTON (9002C)
CARTON 3-050-234-71 INDIVIUAL CARTON (9002B)
CARTON 3-987-178-71 INDIVIUAL CARTON (9002A)
CARTON 3-050-234-81 INDIVIDUAL CARTON (9003)

Some other stuff for various versions:

ADAPTOR 1-569-008-11 ADOPTOR CONVERSION. (9003)
AV 1-777-918-31 CORD, CONNECTION (Except 9002B)
RFU 1-475-177-43 ADAPTOR, RF (9002B)
CONV 1-573-291-11 CONNECTOR, CONVERSION (9002C)

So the SCPH-9002B (UK) variant came with a RF unit, and all others were shipped with a standard (SCPH-1140 type) AV cable.

SCPH-9002C (AEP) version was also shipped with a RCA to SCART adapter

I assume the "ADOPTER CONVERSION" for the 9003 is the one that converts a Euro style mains plug (as used in Korea) into a UK style one (as used in HK).

A picture is not much help, "SCPH102C" on the label and the different feet could be an indicator that it's a clone http://www.bordersdown.net/threads/1071 ... t-Consoles

If the label is the one from the other pictures then it's annoying they hide the type of adaptor, but I would guess it's the "C" European one. The serial number looks very dodgy.

http://moskva.ifreeads.ru/bytovaya-tekh ... 125880.htm

The label says it's made in china, while the other scph102c that are just labelled scph102 are made in japan (and I don't think it means china either).

http://www.ebay.co.uk/itm/Sony-PlayStat ... 487bca4b91

The PM41(2) turned up in consoles marked as SCPH-100/SCPH-101/SCPH-102, you can't tell until you open it up.

No. Just, NO
