Many loaders implement a special protocol, that allows the cube to transmit the Game ID of the currently started game to an MCE. FlipperMCE supports this protocol (see doc/mcp) and will load or create a card for each trasmitted Game ID if configured so.

Mulitple CardSizes

FlipperMCE support Card Sizes from 4 - 64 MBits.

Game2Folder mapping

There are some games, that share save data for multiple game ids. For these cases, a custom game to folder mapping can be created.

If a game with a mapped id is loaded, instead of using the game id based folder, the mapped folder is used for storing the card.

The mapping needs to be defined in .flippermce/Game2Folder.ini in the following way:

[GC]
GT4P=FolderName

Note: Be aware: Long folder names may not be displayed correctly and may result in stuttering of MMCE games due to scrolling. Note 2: Make sure there is an empty line at the end of the ini file.

Settings File

FlipperMCE generates a settings file (.flippermce/settings.ini) that allows you to edit some settings through your computer. This is useful when using one SD card with multiple FlipperMCE devices.

A settings file has the following format:

[General]
FlippedScreen=OFF
[GC]
CardRestore=ON
GameID=ON
CardSize=64

Possible values are:

Setting	Values
CardRestore	`OFF`, `ON`
GameID	`OFF`, `ON`
CardSize	`4`, `8`, `16`, `32`, `64`
FlippedScreen	`ON`, `OFF`

Note: Make sure there is an empty line at the end of the ini file.

Per Card Configs

There are some configuration values that can be modified on a per card base within a config file named CardX.ini in a card folder, where X is the card index.

Note: Make sure there is an empty line at the end of the ini file.

[ChannelName]
1=Channel 1 Name
2=Channel 2 Name
3=Channel 3 Name
4=Channel 4 Name
5=Channel 5 Name
6=Channel 6 Name
7=Channel 7 Name
8=Channel 8 Name
[Settings]
MaxChannels=8
CardSize=8

Card splashes

Add a splash image that the device shows in the card browser. Use the included splash generator (misc/splashgen.html) to convert a source image to the device .bin format, then place the generated file in the card folder on your SD card.

Naming and behavior

Folder-level splash (default for the folder):
- Path: MemoryCards/GC/<card_folder>/<card_folder>.bin
- Example: MemoryCards/GC/SuperGame/SuperGame.bin — used when no channel-specific image exists.
Channel-specific splash (overrides folder-level for that channel):
- Path: MemoryCards/GC/<card_folder>/<card_folder>-<channel_number>.bin
- Example: MemoryCards/GC/SuperGame/SuperGame-1.bin — shown only for channel 1 of that card folder.
Fallback rules:
- If a channel-specific file exists it is used.
- Otherwise the folder-level <card_folder>.bin is used.
- If neither exists, no splash is shown.

Practical notes

<channel_number> matches the on-device channel index (1..N).
Filenames must match exactly; FAT SD cards are usually case-insensitive but keep names consistent.
Use misc/splashgen.html to produce correctly-sized and packed .bin files for the OLED.
Keep names short — very long filenames may cause display or performance issues.
Store splash .bin files alongside that card's CardX.ini and save data in the same folder.

Known issues

wii will not recognize the card as memory card

Within the wii System Menu, the card may occasionally not be recognized. If this happens please try the following things:

Close and re-open Gamecube Cardbrowser
Switch the mounted card using the buttons on FlipperMCE
Re-Plug FlipperMCE
