     note: "Sega CD BIOS for discs whose header allows the default region U, or that carry neither E nor J (segacd.c:1573-1593). An empty file counts as missing (segacd.c:1599-1602). Without it a CD image fails to load (segacd.c:1644-1647). A Mode 1 cartridge runs without it as a plain cartridge (genesis.c:3156-3162)."
