If you own the Game Cartridge gamepass or were present during the entirety of Bus Simulator's 6th Birthday, (or assuming you found a free cartridge in Noble's House) you can host games with other players, with a total of five games you can choose from.
When you start a match with somebody, there will be a Link Cable connected to both of the players' consoles, specifically to the port on top.
- Tic-Tac-Toe, Connect Four, and Battle Wagons are official ROBLOX items that you can buy, but they're currently broken and non-functional.
- The game's title on the Cartridge is called "Bus Routes", and has a map of bus routes on it.
- This is one of the two Nintendo references in the entire game, other one being the Cubes Event.
- The original mesh uploader is unknown.
- There's no link cable length limit between both players when they're in a match, meaning you can still play with somebody at different locations.
- The startup sound when you equip the Gameboy Advance used to be a beta Operating System bootup noise for Codename "Longhorn", which later became the Windows Vista. A clearer version can be heard on Youtube. Unfortunately, it was removed due to a copyright claim.
