Hi, the modern version of CMR does not support single-keyboard multiplayer (here’s why). However, if you only have one controller, the game will let Player 2 use the keyboard.

Hi there! First of all, thank you for bringing these old games back! I still have a running 2001 iBook with all the games on it but it's fun to be able to play them on a newer Mac! I was just wondering what kind of controller would work since we can't play Multiplayer on one keyboard? Any recommendations? I tried connecting an external USB Apple keyboard but it didn't work, so I'm open to (cheap) suggestions.
Thanks a lot!
Hey! I’ve only tested the game on Xbox Wireless Controllers and PlayStation 5 controllers, so I can only vouch for those personally. Apple even has official instructions on connecting them to your Mac (1, 2)
I realize that these aren’t super cheap, but unfortunately I can’t guarantee that the game will work with other makes. However, the input system that I use in the game claims to support some more devices. Looking through the list of controllers that are supposed to work, cheaper options might include “8BitDo Zero 2” ($20) or “8BitDo SN30 Pro” ($40). However, I’ve never tested the game on those, so purchase them at your own risk!
