You need the file called "[BIOS] Nintendo Famicom Disk System (Japan)". It's a .bin file, though it might zipped when you find it. When you get the popup in NSUI that says "Error! Bios file for Famicom Disk System is not specified. Please configure it in options (Bios tab).", go to Tools > Options > Bios tab. Click on the box with the three dots to the right of the field labeled "Famicom Disk System Bios" and upload the aforementioned .bin file and click Save. NSUI should now allow you to convert the game to a .cia and save it to your folder of preference. Then just drag and drop it to your memory card as you would any other .cia file.Can you post your solution in case somebody else has the same problem
