Hello I am new to RetroArch and am looking for help. I have been using Sega CD roms and Neo Geo MVS roms and when I launched them I would receive an error that the bios for those systems was not found. I put them in the system folder and tried again and still received the same error. I was able to google and find out that I needed to put the bios in the folder for each game and then then would launch. I was wondering if that is just how those cores work or if some cores just don’t use the system folder and if their is a list of cores that use or don’t use the system folder for their bios.
Thank you
