Multiplayer can refer to 4P-capable games like Kizuna Encounter - Super Tag Battle using the NEO-FTC1B board, or multi-system cable-linked games like League Bowling, Riding Hero and Thrash Rally.
The linkable cartridges had a dedicated HD6301 µC and used a 3.5mm stereo jack cable to communicate with each other.
Protocol
