If you want more information, read the rest of the page.

You can also use angrylion-rdp-plus (Video) and parallel (RSP).

For Mario Artist Polygon Studio, use parallel (Video and RSP), else the model editors will not work at all.

For almost every 64DD game, use GLideN64 (Video) and RSP plugin (RSP).

Or load 64DD Expansions with File -> Open Combo, then open the Base N64 game, then the Expansion Disk file.

Load 64DD games (*.ndd or *.d64 files) with File -> Open ROM.

Download the Project64 build on this website in the Downloads section.

64DD IPL ROMs and how to boot a disk game.

(Not necessarily the build found on this website.) 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.
