On the Beastcast they said it would be a cool throwback for the Switch version of MK11 to have no blood by default and require a blood code which then had Dan reciting ABACABB but neither 16-bit version of MK1 had blood by default! The blood code was for Genesis, and SNES had no way of enabling blood at all.
Im mad that i remember this being a thing. That Icons show on G4 taught me so much useless shit lol
