For certain systems, you’re going to need BIOS files to properly emulate them. For others, they’re mostly for nostalgic reasons, to get the intro music and jingle. Here’s the list of BIOS names, to help you in your search, as I cannot legally provide them to you. (hint: Google the filename)
All of the below BIOS files are for the USA region only, if your ROMs are EU, or other, you’ll need those regions BIOS files.
Where do BIOS files go?

I’m giving up. I’ve watched your video a dozen times, and I cant figure out how to get different systems in the main Knulli menu like you have in your video. I’m missing several, and I’ve tried installing bios files from at least ten different sites. I get that you aren’t allowed to help for legal reasons, and I get what you said about the first paragraph. It just isn’t working. I’m giving up.
I’m trying so hard to figure this out…
I have a rgcube from Anbernic. Ive installed Knulli, and several games for NES, SNES, etc.. They’re working fine. I’d like to get some Sega CD games, so I need bios files. Everywhere I look, I’m getting different answers. I see codes like yours here on this very website that says “bios_CD_U.bin” and I have no idea what that means. So I google it, and I get a bunch of links for Sega cd bios files. Fine. Then I click on one, and it has another code similar to yours… Am I supposed to just type that code into the bios folder in Knulli? Everywhere I look, it says to add bios files into the bios folder. Fine. Do I download these files? Or just look them up to find the code to type? What am I not doing? And is a Sega CD section supposed to just appear when I start my console? How do I make any of this work?
Hey! The first paragraph of the page sort of explains it, but let me know if I can do a better job of it.
But yes, these are filenames on this page since I cannot legally provide the files, so find the files and put them into whichever operating system or emulators bios folder you’re using.
This helped, big thanks on clarification!
