PlayStation model SCPH-7000W (midnight blue)

I just got the Midnight Blue PlayStation I ordered in the mail today. It's the Japanese version; its model number is SCPH-7000W. This is interesting, because the online pictures I see of the American and European midnight blue systems' labels shows SCPH-7001 and SCPH-7002, without the W, respectively.

I'd take some pictures, but my scanner isn't hooked up yet for a label close-up.

Its CD-ROM firmware appears to act like the Yaroze. It boots both American and Japanese games, but not *ahem* master disks. I don't have a European PS1 game to try with it. Unlike normal retail models, the boot screen does not show the copy protection string (SCEI tm/SCEA tm/SCEE tm). That's like my two debugging stations.

I don't have the Yaroze boot disk to see whether it accepts the "SCEW" copy protection string.

I have a DTL-H1002 and a DTL-H1101. I just need to get an SCPH-5903, a DTL-H300x, and a DTL-H120x to complete the set. Unless you count that weird Men in Black variant Wikipedia mentions. =)

Since I haven't had a computer with an ISA slot in many years, and since it won't boot CD-Rs, can any of you think of a way to dump the BIOS of the system?

 

I have a bios for the SPCH7000

Options I can think of:

You could probably install a modchip to boot cdr... as its clearly looking for the copy protection string, but just accepting any of the legit ones.
take the bios out and dump it externally?
dump via action replay over parallel using a action replay 3 (rather than the PAR1/2 that needs comms link - which is what I assume you were getting at with the ISA slot comment)

 

Yeah, I was referring to a comm-link card. I still have one, but don't have a machine that can use it.

Even with Action Replay 3, how would I use the parallel port connection? This machine doesn't have a parallel port, either.

I suppose that one of those spring things to hold down the disk button to do the swap trick would work to boot a CD-R. Booting a CD-R would then allow writing the data to a memory card. Then I'd need a way to get it off the memory card. Is there a tool to decrypt the PS1 memory card files that were copied to a PS3?

I suspect that the SCPH-7000W BIOS actually has the American SCPH-7001 BIOS, even though it is a Japanese system. The CD player is in English, despite it being in Japanese on a retail PS1. Also, since it's able to boot American PS1 games, it also doesn't have the license area checks that the 5000+ series Japanese PS1s normally do.

 

Find a machine with a parallel port, which is much easier than finding one with a ISA slot. You are going to have to do some sort of work to get this done, you just seem to want a solution handed to you...

 

I have to ask...


How much did you pay for it?

 

According to this picture/description, the midnight blue model you have is the 10 millionth model... I didn't know these were "region-free".

 

DO NOT MODCHIP, NOR OPEN THIS PLAYSTATION.
You have the '10 Million Model' that Sony released.

(Sorry Pool for the takeover)


Seeming as it is a 7000 series, it will have a Parallel Port.
So, to dump the BIOS, you will need a Xplorer with CAETLA 0.35 running or a FreeWing.

Thanks for repeating what was already said about dumping the bios.

Also, the PS1 has no stickers over the screws - you can take it apart as much as you like.

 

I don't think the OP was planning to install a modchip; this was just suggested by Bad_Ad84.
I do agree with not doing it, but it's up to the OP.

Anyway, I love the looks of this particular model; too bad collecting consoles (especially LEs) is way out of my reach...

 

I also didnt tell him to install a chip. I just gave a list of options that would get him a bios dump, what he does is up to him.

 

Uh, yes you did...? Probably still counts as both yes and no (50-50).
Bad_AD84: "You could probably install a modchip to boot cdr".

Either way, we are now off topic. You just need an AR3 or Xplorer with CAETLA 0.35 on it, and a PC with a parallel port for communication between the two.
If you can't do it yourself, then get the console shipped over to me where I can dump it in less than 1 minute for you. No opening the console and no messing around. Just pay the shipping costs both ways.

 

Seriously?

(Also, you have misquoted me to remove the context of that line)

It was a list of options that would complete his goal. Not "you should install a modchip". Whether or not its a good idea or something the OP wants to do is up to him. Your comment saying you NEED a PAR3 is incorrect - clearly. He asked for options, he got them. Pretty simple concept.

Id also like to point out, you are also just repeating what I have already said about the PAR3.

 

LOL, your answer haunted make me laught very much

Do not get a lot of mental blowjobs (XD) and install a modchip. This is the easiest way with less problems
Then build a dexdrive

This playstation it's only a 7000 PU20 board with a blue case. That's all...

 

I got the dumper disk to boot using a swap trick. I just need to get a serial to USB adaptor now, so I can hook up my old DexDrive.

It's more than that. It's probably a 700x board with the 7001 American BIOS (despite being the Japanese model) and the Yaroze CD controller firmware. I'll confirm my suspicions the former soon. The latter can only feasibly be checked by trying to boot the Yaroze boot disk on the system, which I don't have.

The seller said that it would only boot Japanese games, but that's incorrect. It boots my American PS1 games just fine. That's why I think it has the Yaroze CD controller.

 

1) You're welcome for the lol's
2) Uhh, what the fuck?
3) No. Do not install a modchip.
4) Not everyone can build a DexDrive in a snap just like that.
5) If thats all, then why has it not been dumped/released before? Maybe because it is the 10 million model.

 

Or its identical to the other bioses

 

I won't start flame with haunted but
1)you lolled me much because you talks like you're the authority of all things PS1, but you know nothing
2)????
3)why? because change only the case but the mobo is the same?
4)dexdrive are only few components linked to a normal db25, the cost about 2$.
It sems you are the only electric engineer (lol, insulant tape corrode the board. roftl)
If he won't build the dex drive, he can simply buy a ps3 memory card adaptor and use a program to use with pc.
This solution is less problematic compared to buy a xplorer that work with parallel port and use an very old program written for old win98 s.o.
5)It's not relased because it's a normal 700x bios! The only change it's the case!

At 99% serial to usb converter don't work.
Buy a pci card with serial port

I've never seen a JAP mobo with US bios...
And it's very strange that haven't the parallel port...
Maybe in the playstation there's another board?

 

Well, it was a pain in the ass to get it, but I have it now. I used my old DexDrive with a crappy USB-to-serial adaptor, and got the output image. Its MD5 and SHA-1 don't show up in Google; this probably just means it's a bit corrupted somehow. Wouldn't surprise me, due to this cable apparently being a Chinese knock-off.

Anyway, these are its identifying strings:
CEX-3000/1001/1002 by K.S.
System ROM Version 4.1 11/14/97 A

I was right - it's an American BIOS.

The seller either didn't switch out the board, or switched it out with a Yaroze. The former is far more plausible, so this is an "NTSC J"-labeled system with an American BIOS. It has the Japanese-style power cord (symmetric), though.

MD5: B84BE139DB3EE6CBD075630AA20A6553
SHA-1: 1B0DBDB23DA9DC0776AAC58D0755DC80FEA20975
SHA-256: B3AA63CF30C81E0A40641740F4A43E25FDA0B21B792FA9AAEF60CE1675761479

 

It's a normal scph 7001 bios, not a yaroze.
Open a scph 7001 bios with hex editor and you find the same string.
Japanase power cord means nothing, can you check the board?

 

Doesn't the Playstation determine region by means other than its BIOS? I've certainly never seen a PS1 region free BIOS in the matter of Sega CD, Saturn, or Dreamcast.
