Aims

• 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.

Experimental features

These features are subject to change:

N64 ROM autoload

To use the autoload function, while on the N64 ROM information display, press the R button on your joypad and select the Set ROM to autoload option. When you restart the console, it will now only load the selected ROM rather than the menu. NOTE: to return to the menu, hold joypad start button whilst powering on the console.

GamePak sprites

To use N64 GamePak sprites, place PNG files within the sd:/menu/boxart/ folder.

Supported sprites

These must be PNG files that use the following dimensions:

• Standard N64 GamePak boxart sprites: 158x112
• Japanese N64 GamePak boxart sprites: 112x158
• 64DD boxart sprites: 129x112

They will be loaded by directories using each character (case-sensitive) of the full 4 character Game Code (as identified in the menu ROM information). i.e. for GoldenEye NTSC USA (NGEE), this would be sd:/menu/boxart/N/G/E/E/boxart_front.png. i.e. for GoldenEye PAL (NGEP), this would be sd:/menu/boxart/N/G/E/P/boxart_front.png.

To improve compatibility between regions (as a fallback), you may exclude the region ID (last matched directory) for GamePaks to match with 3 letter IDs instead: i.e. for GoldenEye, this would be sd:/menu/boxart/N/G/E/boxart_front.png.

Note1: Excluding the region ID may show the wrong boxart. Note2: For future support, boxart sprites should also include: boxart_back.png, boxart_top.png, boxart_bottom.png, boxart_left.png, boxart_right.png.

As a starting point, here is a link to a boxart pack following the new structure, including boxart_front.png and failback images:

Compatibilty mode

If you cannot yet satisfy the correct boxart layout, The menu still has deprecated support for filenames containing the Game ID.

Note: This will add a noticeable delay for displaying parts of the menu.

Each file must be named according to the 2,3 or 4 letter GamePak ID (matched in this order). i.e.

• for GoldenEye 4 letters, this would be sd:/menu/boxart/NGEE.png and/or sd:/menu/boxart/NGEP.png.
• for GoldenEye 3 letters, this would be sd:/menu/boxart/NGE.png.
• for GoldenEye 2 letters, this would be sd:/menu/boxart/GE.png.

As a starting point, here are some links to boxart packs:

• Japan Boxart
• American Boxart
• European Boxart
• 64DD Boxart

Menu Settings

The Menu creates a config.ini file in sd:/menu/ which contains various settings that are used by the menu. If required, you can manually adjust the file on the SD card using your computer.

Flashcart specific

SC64

• 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.

64drive

• 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.

ED64 - WIP - UNTESTED AND UNSUPPORTED - USE AT OWN RISK

Currently not supported, but work is in progress (See PR's). NOTE: The menu may be able to load ROM's but not perform saves and may break existing ones..

ED64 (Vseries)

The aim is to reach feature parity with ED64-UnofficialOS / ED64-OfficialOS. Download the OS64.v64 ROM from the latest [action run - assets] and place it in the /ED64 folder.

ED64 (X series)

X Series support is currently awaiting fixes, in the meantime use the official OS instead.

ED64 (P clone)
