First time setup of SD card

Using your PC, insert the SD card and ensure it is formatted for compatibility with your flashcart (FAT32 and EXFAT are fully supported on the SC64).

• Download the latest sc64menu.n64 (assuming you are using an sc64) file from the releases page, then put it in the root directory of your SD card.
• Create a folder in the root of your SD card called menu.
• Place your ROMs on the SD Card, in any folder (except for menu).

Emulator support

Emulators should be added to the /menu/emulators directory on the SD card.

Menu currently supports the following emulators and associated ROM file names:

• NES: neon64v2 by hcs64 - neon64bu.rom
• SNES: sodium64 by Hydr8gon - sodium64.z64
• Game Boy / GB Color: gb64 by lambertjamesd - gb.v64 / gbc.v64 ("Download Emulator" button)

64DD disk support

For the ability to load and run 64DD disk images, you need to 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.

So what would the layout of the SD Card look like?

            └── (Some 64DD disk images)

Save Files

All save files (whether FlashRam, SRAM or EEPROM) use the .sav extension and match the filename of a ROM.

Each save file can be found in the /saves folder located in the same directory as the ROM and shares the same file name, apart from the extension. These files are created and modified when a "game" saves.

├── (some folder with roms)\
    ├── a_rom.z64
    ├── b_rom.n64
    └── saves\
        ├── a_rom.sav
        └── b_rom.sav

Transfering saves from an ED64

If transferring a file from a different flashcart, such as the ED64, it will be necessary to change the extension of the file to sav.

i.e. for Glover (USA).eep you would need to change the extension to Glover (USA).sav

You may also need to pad/trim the files to their original size:

• For EEPROM 4Kbit games, remove the padding.
• For others, use a tool such as Ninjiteu's N64 Save converter.

NOTE: certain emulator saves or saves created for a different ROM version or region may be incompatible.
