I'm not sure if I came to the right place or not but I am looking for Consumer Editions: SCPH-7500, SCPH-7503, SCPH-9000, SCPH-9001. Developer Editions: DTL-H1201, DTL-H3001, SCPH-2000.
The Following doesn't work at all.
SCPH-7500 & SCPH-9001 an there in .S19 instead of .bin an when I change it to .bin it doesn't work at all so I really hope that i came to the right please.

Looks like Redump Team BIOS checksums are wrong they mix a lot of different BIOS into one. I hope they'll double check that to avoid inconsistencies.

Hello! I'm new to the PSXDEV website and just registered to the site. But I just want to pop on by and say that I got the SCPH-9001 BIOS dumped and released.

Can you also provide the PCB name and the chip part number? Like those listed here, viewtopic.php?f=70&t=1065
Most of the ROMs are already dumped, we just don't know where they were dumped from. If you want to contribute really new and unique information, include those PCB names and part numbers!

I would like to do that, but I don't want to risk taking appart my PS1. The last one I took appart, the connector for the disc drive broke off the board.

I've had that happen too. It's due to a lack of solder paste from the factory which Sony used to manufacture the PlayStation 1. All you gotta' do is re-solder it. Really easy task. Just use a good soldering iron, a clean tip and flux and you'll be fine. If you use one of those cheap 60W soldering irons with a crusty old tip on it, you'll just ruin it so don't bother if you don't have the right tools for the jobR7CrazyCanucks wrote: ↑April 24th, 2023, 3:20 am I would like to do that, but I don't want to risk taking appart my PS1.

Here is a dump from my personal SCPH-9001. Modchip is Mayumi V4. Included are images showing the console itself including the underside sticker, and a couple PCB/IC shots.
I was just shy of being able to include a full motherboard shot in the archive, so here it is: Motherboard is a 1-674-987-31, PU-23. BIOS Version 4.1, the BIOS chip itself says "SONY COMPUTER ENTERTAINMENT INC.C 2041 9948 0" and the Mechacon says "C 2060 SC430944PB G630 135 SSMM9945A".
Hope that's all the info needed, if not please let me know.

Thanks for the part numbers, I have added them to the http://www.psxdev.net/forum/viewtopic.php?f=70&t=1065 thread

Of course! I have access to many PS1s at work, I plan on dumping any missing BIOS files I can find and will be on the look out for unidentified part numbers as well.
Cool. Depending on what hardware you have, it might easier/faster to just check if the CRC32 of the BIOS memory does match up with known dumps. For example, in this tool http://www.problemkaputt.de/psx-diag.htm select "General Tests", and it'll compute the CRC32 and display it on the TV screen.
EDIT: This tool can also display the CRC32, http://www.psxdev.net/forum/viewtopic.php?f=62&t=395
