Documentation
Video showcase (as of Oct 12 2023)
Aims
- Support as many N64 FlashCarts as possible.
- Be open source, using permissively licensed third-party libraries.
- Be testable in an emulated environment (Ares).
- 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.
The autoload setting is stored in config.ini
and persists until changed. This feature may slightly increase boot time as the menu needs to check for the Start button state.
NOTE: To return to the menu, hold the joypad Start
button while 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
Supported PNG formats:
- RGB/RGBA color formats
- 8-bit color depth
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
.
Warning: Excluding the region ID may show the wrong boxart. Note: 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 fallback images:
Compatibility 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/orsd:/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 image packs:
Menu Settings
The Menu creates a config.ini
file in sd:/menu/
which contains various settings that are used by the menu.
These can be updated using the settings editor, but if required, you can also manually adjust the file on the SD card using your computer.
