An impressive new Super Odyssey 64 romhack has been released, bringing the gameplay mechanics and levels from Super Mario Odyssey on the Switch to N64’s Super Mario 64.

Created by well-known romhack creator Kaze Emanuar, the new Odyssey 64 romhack works with N64 emulators on PC and requires players to patch their Super Mario 64 rom in order to work. We’ve included a video from the Super Mario Odyssey 64 Mod down below, which also includes instructions on how to get it working.
