• Music playback (MP3).

• Support as many N64 FlashCarts as possible.
• Be open source, using permissive licensed third party licensed libraries.
• Be testable, using unit and smoke tests in ares emulated environment.
• Encourage active development from community members and N64 FlashCart owners.
• Support as many common mods and features as possible.

Using your PC, insert the SD card and ensure it is formatted for compatibility (We recommend FAT32 in most instances).

By default, all save files (whether FlashRam, SRAM or EEPROM) use the .sav extension and match the filename of the 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.

If transfering 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

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

To use boxart, you need to place png files of size 158x112 in the folder /menu/boxart on the SD card. Each file must be named according to the 2 letter ROM ID, or 3 letter ROM ID including media type. i.e. for GoldenEye 2 letters, this would be GE.png. i.e. for GoldenEye 3 letters, this would be NGE.png. A known set of PNG files using 2 letter ID's can be downloaded here.

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
• Sega Master System / Sega Game Gear / Sg1000: TotalSMS - TotalSMS.z64 (Currently broken)

The Menu creates a config.ini file in sd:/menu/ which contains various settings that are used by the menu. Currently these are read-only (can be viewed in the menu by pressing L on the Joypad). If required, you can manually adjust the file on the SD card using your computer.

• Ensure the cart has the latest firmware installed.
• Download the latest sc64menu.n64 file from the releases page, then put it in the root directory of your SD card.

For the ability to load and run 64DD disk images, you need to add the folder /menu/64ddipl on the SD card. Download and add the relevant ipl files and rename them before adding them to the folder:

• NDDE0.n64 the US Prototype IPL can be downloaded from here
• NDXJ0.n64 the JPN Development IPL can be downloaded from here
• NDDJ2.n64 the JPN Retail IPL can be downloaded from here

Note: to load an expansion disk (e.g. F-Zero X) browse to the N64 ROM and load it (but not start it) and then browse to the DD expansion file and press the R button.

• Ensure the cart has the latest firmware installed.
• Download the latest menu.bin file from the releases page, then put it in the root directory of your SD card.

Currently not supported, but work is in progress (See PR's).

The aim is to replace Altra64 and ED64-UnofficialOS.

You can use a dev container in VSCode to ease development.

• Download the deployer here
• Extract and place sc64deployer.exe in the tools/sc64 directory.

Make sure that your firmware is compatible (currently v2.18.0+) See: here

It is not currently possible to directly communicate with USB devices. BUT, as a work around you can use a proxy TCP/IP connection Set up a proxy: open a terminal window, cd ./tools/sc64 and then ./sc64deployer.exe server

Then in the dev container, use make run or make run-debug

• Run ./localdeploy.bat from the terminal

Toggle the N64 power switch to load the ROM.

ms-vscode.makefile-tools will help (installed automatically in dev container). TODO: it does not yet work with F5: see https://devblogs.microsoft.com/cppblog/now-announcing-makefile-support-in-visual-studio-code/ WORKAROUND: in the dev container terminal, use make directly, i.e.: make The ROM can be found in the output directory.

NOTE: a "release" version of the SC64 menu is called sc64menu.n64 and can be created for when you want to add it directly to the SDCard. This is generated by running make all or running make sc64.

• Add the required file to the correct folder on your SD card.

This repo currently uses the unstable branch as a submodule at a specific commit. To update to the latest version, use git submodule update --remote from the terminal.

Run doxygen from the dev container terminal. Make sure you fix the warnings before creating a PR! Generated documentation is located in output/docs folder and auto published to the gh-pages branch when merged with main.
