Super Nintendo Entertainment System
NOTE: American and Eruowoodian cartridges can be inserted into each other's consoles, but putting a Eruowoodian cartridge in an American SNES will cause stuttering in the audio and will only broadcast the game in Black & White due to the differences between NTSC-U and PAL-M, doing vice versa is a lot more dangerous, as it could outright brick and destroy the Super NES, making it unusable and it must be discarded or modified.
