Nintendo 64DD Set Up

[SiriusVI]

Hey everyone,

I've been trying to set up Nintendo 64DD within Retroarch and I've gotten most games working. Therefore, I wanted to share what I've learned along the way.

I'm using the mupen64plus next core with ParaLLEl RDP and RSP. As for the N64DD games, I'm using the original Japanese dumps, no translation hacks (I haven't tested those, yet), and no cartridge conversions.

Dezaemon DD and F-Zero X - Expansion Kit are expansions, which need specific N64 roms to load. The rest of the games are standalone, but still need an N64 rom to properly load. I'm using Super Mario 64 all of them, except for Kyojin no Doshin (Doshin the Giant), which for some reason won't load with Super Mario 64. I'm using Air Boarder 64 for that game.

What you'll need:

1. The Japanese BIOS file version 1.2

2. The Japanese N64DD disk games

3. The Super Mario 64 (Japan) rom

4. The F-Zero X (Japan) rom

5. The Dezaemon 3D (Japan) rom

6. Another random Japanese N64 rom (I'm using Air Boarder 64 (Japan))

So here's the set up:

1. For the Japanese games, the Japanese BIOS file version 1.2 must be placed inside "RetroArch\system\Mupen64plus" and renamed to "IPL.n64" (the .n64 file extension is important, the z64 file can just be renamed, no need to convert it in any way).

2. Import the N64DD games into LaunchBox (the files can be zipped, no need to extract them).

3. In Launchbox, go to manage emulators --> Retroarch and find the Nintendo 64DD platform. Under Extra-Command-Line Parameters add:

--subsystem ndd %romfile% "PATH TO\Super Mario 64 (Japan).zip"

This should load most of the standalone games.

4. Go back to your N64 DD platform and find the Dezaemon DD game. Right-click and go to edit. Under "Emulation" enable Custom Command-Line Parameters and insdert:

-L ".\cores\mupen64plus_next_libretro.dll" --subsystem ndd %romfile% "PATH TO\Dezaemon 3D (Japan).zip"

5. Go back to your N64 DD platform and find the F-Zero X - Expansion Kit. Right-click and go to edit. Under "Emulation" enable Custom Command-Line Parameters and insdert:

-L ".\cores\mupen64plus_next_libretro.dll" --subsystem ndd %romfile% "PATH TO\F-Zero X (Japan).zip"

6. Go back to your N64 DD platform and find the Kyojin no Doshin game. Right-click and go to edit. Under "Emulation" enable Custom Command-Line Parameters and insdert:

-L ".\cores\mupen64plus_next_libretro.dll" --subsystem ndd %romfile% "PATH TO\Air Boarder 64 (Japan).zip"

7. For Sim City 64 to be able to go past the title screen, make sure that in the mupen plus core options, the follwoing settings are set:

• "Framerate" must be set to "Original", "Fullspeed" causes a black screen past the initial logos.
• Under "Pak/Controller Options", if player 1 (and possible the other players?) has a rumble pak inserted, it also doesn't work (same as above). Memory pak works.

That's it. I've not tested playing much, but as far as I can tell, this is how to get almost all of the games working. There are 2 roms, I'm still having trouble with (maybe someone can offer a solution?):

1. The Randnet Disk does launch, but once the title screen shows "press start", nothing happens. Pressing start on the controller won't do anything. I know that this isn't a game, but it would still be nice to enter the program, just out of curiosity.

2. Kyojin no Doshin - Kaihou Sensen Chibikko Chikko Daishuugou (Doshin the Giant: Tinkling Toddler Liberation Front! Assemble!) is an add-on / add-in for the Doshin the Giant disk. It does Launch, but it won't go in-game. If I understood correctly, in order to get this game to work, you'd need to be able to swap between the Doshin the Giant disk and this add-on disk, and I don't think this is possible with mupen. If anyone know of a way to do this, please share!

I hope this helps someone!
