Freeing Marty the Thwomp in Mario Kart 64

Hack of Mario Kart 64


In Mario Kart 64 there is a green thwomp mysteriously locked behind bars in Bowser’s Castle. He has been unofficially named Marty and has been the subject to longstanding rumors that he can actually be unlocked as a playable character. Several hoax and April fools joke images and videos have popped up over the years supposedly showing the convoluted things you need to do on the track in Bowser’s Castle to unlock Marty as a playable character. Well now you can finally race as him with this hack! The current version works only in Bowser’s Castle for Player 1 but it works for all engine classes and in both Time Trial and VS. mode (so you can play your friends as Marty).

Watch the video:

Requires the expansion pak to run.

See the readme for more details.
