64DD Disk support

Specific flashcarts (such as the SummerCart64) can fully emulate the original 64DD (load, run, save) disks without having a physical device connected to the N64 and don't require conversion ROMs.

To load and run 64DD disk images, place the required 64DD IPL dumps in the /menu/64ddipl folder on the SD card. For more details, follow this guide on the 64dd.org website.

Remarks: Expansion disks expect the same region as the ROM image (Japan -> Japan | US -> US).

Warning: It is not yet possible to swap 64DD disks via N64FlashcartMenu, though this feature will be added in future.

Conversion ROMs

The N64Flashcart Menu is able to load and run conversion ROMs (but does not perform saves).
