Which BIOS files do I need?
Hello. Sorry if this has been asked countless times before, but I don’t know whether there are obvious websites to avoid, and I don’t want to download viruses. I would really appreciate help with this.
(I’m using a Lenovo laptop with Windows 11; I downloaded DuckStation from duckstation.org just today, so I’m assuming it’s the most recent version.)
People in this subreddit have said to go to Internet Archive, but I’m not sure what files to download from there.
A website called psbios.me says ‘Download PS1 BIOS Files for All Regions — USA, PAL, NTSC, NGSC-J’. It presents four download options:
* SCPH1001.BIN (USA)
* SCPH7502.BIN (PA)
* SCPH5500.BIN (Japan)
* SCPH7003.BIN (Worldwide)
I can see the following similar files in ‘Files for the-ultimate-playstation-1-bios’ on Internet Archive:
* SCPH1000.BIN
* SCPH1001.BIN
* SCPH1002.bin
* SCPH101.BIN
* SCPH3000.bin
* SCPH3500.bin
* SCPH5000.BIN
* SCPH5552.bin
* SCPH7001.BIN
* SCPH9001.BIN
* SCPH7001.bin
* SCPH7003.bin
* scph100 (psone-43j).bin
* scph101 (psone-44a).bin
* scph101 (psone-45a).bin
* scph102 (psone-44e).bin
* scph102 (psone-45e).bin
* scph5500.bin
* scph5501.bin
* scph5502.bin
* scph5903 (ps-22j(v)).bin
* scph7000w (ps-41a(w)).bin
* scph7502.bin
Is it a problem that some of these are in uppercase and some are in lowercase? (The answer is probably very obvious. Sorry about that.)
Are the psbios.me files the correct files? If so, should I download them from there, or from Internet Archive?
Also, the Wizard seems to want NTSC-J, NTSC-U/C, and PAL. Is the Worldwide one unnecessary?
If all of these are incorrect, what should I download instead?
