Unable to use PSXONPSP660 with Beetle

[Settsational]

Hello, I heard that the PSXONPSP660 bios is generally the best for original Playstation game performance. However when trying to load a game with only it in the folder, it fails saying it can't find the correct bios.
I could rename it to the bios file that is missing, but that's usually a bad idea.
It shows up as an optional BIOS, but I don't see an override setting anywhere, though on the git, it seems this feature was added?
What am I missing?
Thanks!

Try the other bios:

Load the core but not the game. Go to core information and it should say whether it's present or not. If it isn't, then check the naming because Beetle is very picky with spaces and lowercase letters.

Thanks, I read the documentation, but I don't have the option to select this:
"For Beetle PSX to recognize either of these BIOSes, you need to enable the "Override BIOS" option."

I thought I was missing something, tried rebooting, but I don't see it in any core or option. Reinstalled via Steam and still can't get it setup :(

Thanks for the fast response!

I see it as optional, but don't see a way to select or force it for a core?
Does it use it automatically?
If I remove the 5500s bios, it fails to load, so not sure.
