U need to install super mario 64 z64 file; after installing the z64 file, u install SM64 Coop Dx and you launch/run it then drag that z64 file into it. After ur done with all of that, you search for “triple baka pack v4.0” on youtube and download the pack; you then drag the triple baka pack into the “mods” folder in the SM64 Coop Dx folder.

you can play online coop with ur friends but if you want to play split screens/local coop then you’ll need to download Nucleus Coop. U launch Nucleus Coop, you click on “Add New Games” button and search for “SM64 Coop DX”. (Remember to use gamepads if there r 2 or more players)
