Initial Setup of an SD Card

First steps

Insert the (Micro) SD card to your PC and ensure it is properly formatted to be compatible with your flashcart.

Preparations for SC64

Tip

Most (Micro) SD cards are factory formatted to FAT32 or EXFAT and don't require re-formatting.

• Download the latest sc64menu.n64 file from the releases page, then put it in the root directory of your Micro SD card.
• Place your ROM files on the Micro SD card, in any folder except the root directory menu folder.
• Remove the Micro SD Card from your computer and insert it into the SC64.

Preparations for OTHER supported flashcarts

• It is recommended to format the SD Card to FAT32 with the default cluster size.
• Download the latest menu file specific for your flashcart and place it in the expected location.
• Remove the Micro SD Card from your computer and insert it into the flashcart.

Advanced Steps

Advanced steps are optional, which adds additional capabilities.

Add Emulator support

See the Emulators page.

Add 64DD Disk support

See the 64DD page.

So what could the layout of the SD card look like?

Save Files

All save files (whether FlashRam, SRAM or EEPROM) will be read from a /saves folder located in the same directory as the ROM and they must share the same file name, but use the .sav extension. .sav files will be created and modified whenever a ROM file saves to the "cartridge save memory".

├── (some folder with ROMs)\
    ├── a_rom.z64
    ├── b_rom_whatever.n64
    └── saves\
        ├── a_rom.sav
        └── b_rom_whatever.sav

Transferring saves from an ED64

If you are transferring a file from a different flashcart, such as the ED64, you must change the file extension to sav. For example, a save file called Glover (USA).eep should have its extension changed to Glover (USA).sav to work with N64FlashcartMenu.

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 N64SaveConverter.

Caution

Saves created with certain emulator versions, or created for a different ROM version (as in revisions of the same game), or region (as in between NTSC and PAL versions of a same game) may be incompatible.
