The previous disk you have used will be saved beforehand. Simply use “Swap Disk” option under the System menu (or Ctrl+D), and load the disk you want. Swapping disks is very easy, however, it has be known: You have to swap when the game tells you that you can. This is useful for loading F-Zero X + F-Zero X Expansion Kit and Dezaemon 3D + Dezaemon DD prototype for exemple. Via Command Line: Project64.exe -combo Select the N64 ROM, then select the 64DD Disk file. Via Main Menu: Select File, then Open Combo. Via Game List: Right click a N64 Game in the list, and select “Load Game with Disk”, then select the 64DD Disk file to load alongside it. When it comes to combo load Cartridge + Disk at the same time, there are now several ways: You can then load your 64DD disk game (*.ndd or *.d64 files) just like any other N64 ROM, via the game list, drag ‘n drop, and all that.

This page will assume you are using Project64 v3.0 or later. What I’m interested to talk about are the Graphics plugins, the N64 Mouse support and how to load 64DD IPLs, required to play the games. I will assume you know how to set the controls and stuff. You can either download the original dumps, or the cartridge ports (but I don’t recommend those) both work.

Project64 2.2 (and every versions before) doesn’t support 64DD at all, so you need a development version that you can find on the Download page.
