Getting started

SC64

Ensure the cart is running the latest firmware. Download the sc64menu.n64 ROM from the latest action run assets. Add it to the root folder on your SD card.

ED64 & ED64P

Currently not supported, but there is an aim to do so. The aim is to replace Altra64 and ED64-UnofficialOS.

Common to all

ROM Boxart

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. e.g. for goldeneye, this would be GE.png. A known set of PNG files can be downloaded here.

Emulator support

Emulators should be added to the /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

Developer documentation

Work in progress!

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

To deploy:

SC64

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

Make sure that your firmware is compatible (currently v2.16.0+) See: https://github.com/Polprzewodnikowy/SummerCart64/blob/v2.16.0/docs/00_quick_startup_guide.md#firmware-backupupdate

From the devcontainer

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

From your host (Windows) OS

• 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.

Update Libdragon submodule

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.

Generate documentation

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.
