I found in internet this files:
SCPH1001.BIN crc32=37157331 (A) Ver 2.2
SCPH5000.BIN crc32=24FC7E17 (J)v2.2
scph5500.bin crc32=FF3EEB8C (J)v3.0
SCPH7001.BIN crc32=502224B6 (U)v4.1
scph7502.bin crc32=318178BF (E)v4.1

I am intersting:
1. Are this files "correct"?
(All use this files?)
2.Do you now latest(greater) bios version
(and filename) or 4.1 is last?

I think the latest psx bios file is something like 9002 and is the bios that comes on a PSone. The bios files that work best with emulators are scph1001, scph7502, and maybe a few others such as dtlh3002, but those are the main ones that work.

hi!

the SCPH-9xxx are not the PSOne, they are the latest PSX without the parallelport. And that's the reason why there aren't any dump's ... because nobody* can dump the bios without this port

*Nobody who want to share them with us ... i am sure there are dump's currently

The PSone bios is called SCPH-1xx (100,102...) as far as i know, and it doesn't work with PSX emu's (Crash on the start).

Thanks, but how about 1 question?

Thanks, but how about 1 question?
(same files are you using? check crc)

I thought your 1 question was asking about which files we use. Well I use dtlh3002.bin and it works great. The other files that have been tested are scph1001.bin and scph7502.bin. If this doesn't answer your question then try asking it in another way.

He's asking for a CRC check to determine if what he's downloaded is usable. Well, the simple solution to this, rather than asking people to dig up how to build a checksum, is to simply try the BIOS. You can't hurt anything, if it works at all, it's good. If it doesn't work, then you've got a bad dump.

hi!

I think the best way to find out whether they work or not, is to load them in a emu and try them out

Also you could try to load the files in the attached program ... if it detect the files correctly, they are correct.
