I can't see the way to set up neo geo cd Unibios. I was searching on retroarch settings to change bios and I don't see the option. I have neogeo.zip, neocd.zip and neocdz.zip . Even my perception is that is always using neocdz.zip, I added unibios cd file in neocdz.zip.
I'm using the latest version of Recalbox 6.1
Pls Any advise?
