PlayStation Model: DTL-H1200

Re: [DOWNLOAD] PlayStation 1 BIOS Collection

Post by PixelButts » July 9th, 2014, 3:30 pm

I have a DTL-H1200 and have no idea how I would go about dumping the BIOS. I looked at the methods given, but don't want to spend a fortune doing so.

I'm wanting to share the BIOS of this model, but am lost on what to buy and how to do so. Any help?

Seeming as it's a debugging station with the unlocked mechacon, you can boot CD-R's and in which case, boot some code that will send the BIOS over a serial cable to your PC which will assemble the BIOS binary. Just find yourself a serial cable that operates at 3V. You just need transmit (Tx) and receive (Rx). Handshaking is not required. Oh, 5V will work too, but it's not recommended. Any higher, and you will blow the diodes. If they don't blow quick enough, some current will leak into the CPU and blow it also. Not completely, but the controllers and memory cards MAY stop working. It depends how the internals of the CPU are wired on that particular bus, but I'm almost certain they will share the same bus internally.

If you can't do this, then don't worry. There is NOTHING special about the H1200 BIOS ;)
Everything special is in the mechacon, and we have already dumped it.

Oh, well thanks for the info. I'll get around to this eventually whether it's special or not :lol:
I did just get it signed by Keiji Inafune, so it's special in that regard.

Thanks!

I see that we are missing SCPH102. I think I can help.
Actually I just found out there are two different SCPH102s - 102a and 102b.
I think the bios may be different in each. I think the music visualizer changed a little bit, but I could be wrong.
If I work out how to perform a bios dump safely I will get them up.

I have SCPH-7501, but I have no idea how to connect a memory card to my laptop computer to get the BIOS. All I have for input is USB and CD/DVD.

I also saw SCPH-9001 for sale recently. I don't know if it's still in the store.

Just a thought: can the PS1 burn discs?

There are at least two SCPH-102 bios versions, with CRC32=0BAD7EA9 (v4.4e) and CRC32=76B880E5 (v4.5e), I would be surprised if they aren't already somewhere in the internet.
Before transferring dumps to a PC, it may be easier to use some utility that checks if the BIOS'es CRC32 is already known & dumped.

For the SCPH numbers, I believe that are four different models: SCPH-102, SCPH-102A, SCPH-102B, and SCPH-102C (going by sticker at the bottom of the console). The differences between that models are unknown though. Hires photos of the mainboards of the different models would be very interesting (and if turns out that some of them contain the new PM-41(2) mainboard, a dump of the CDROM firmware would be also very interesting).

There are also three scanned user manuals in the internet, named "SCHP-102 A", "SCHP-102 B", and "SCHP-102 C" (with a space between 102 and trailing letter). The difference there seems to be simply whether the console was shipped with english or multilanguage manual, and with or without AV cable. I am not sure the letters on the sticker have the same meaning as the letters in the manual. Btw. did anybody ever see similar letters on SCPH-100 or SCPH-101 models?

I don't think that anybody has ever tried to do that. But no... I don't think that it can do that.
(it would be a bit like discovering that the C64 did have built-in WLAN support).

If you try it, you will just burn out the laser diode. It will never be able to melt the dye layer in a CD-R.

I do software, not hardware. What's this dye layer? Aren't CDs just plastic?

Any idea how I can connect a memory card to USB?

CD-R's are not just 'plastic'. If my memory serves me correctly, they are a composed of a polycarbonate substrate, dye (old discs would use cyanine, but nowadays they use phthalocyanine for higher stability), aluminum (the Al is sputtered on as a film and not evaporated on), a coat of lacquer (ultraviolet light to cure the lacquer coating) and lastly followed by the masked on label (it's basically screened on). Pressed discs (EG: PlayStation discs) are made differently so do not treat them the same.

As for the USB Memory Card solution, I've never used USB for that since I've always used the parallel port to dump it using a circuit I made that can be found here:

List of topics: viewtopic.php?f=49&t=172&hilit=links+alive
Direct link: http://www.raphnet.net/electronique/psx ... ardmgr.php

Take my advice. Don't use the Memory Card method. Use Shendos tool the serial cable option to dump it.

The SCPH5000.bin file that you added is a confirmed bad dump. The correct SCPH-5000 dump matches the DTL-H1200 and the DTL-H3000, at least, according to MESS ( http://git.redump.net/mame/tree/src/mess/drivers/psx.c ) and according to logic :D

There are at least two more PAL-PSones: SCPH-102 and SCPH-102C.

Oh, in the in the list, you've called the dumps SCPH-102-A and SCPH-102-B, but as far as I know, the official name (on the sticker at the bottom of console) should be SCPH-102A and SCPH-102B.

I have my SCPH-7000W (Japanese Midnight Blue) BIOS file somewhere. I wouldn't know where to upload it, though.

The SCPH-7000W has the same version number tag as other SCPH-7000's, but a different date. I have no idea what the difference actually is. I doubt it's significant - the CD controller "sub CPU" has the interesting BIOS. The SCPH-7000W is the only non-Yaroze known to run imports but not copies, I believe.

The SCPH-7000W has an American BIOS, despite nominally being a Japanese system. My guess is that this is because American PSX's don't care about the license area, and thus would be good for running imports.

The American and European Midnight Blue PSXes don't run imports, as far as I understand.
