An enhanced Miyoo Mini SD card package, translated, cleaned up, debloated.
- fully working RetroArch app, you can load roms and cores directly from the RetroArch menu if you want to
- only includes cores that have been tested to work
- cores and systems are properly configured (aspect ratios, video filters)
- proper key mapping for RetroArch hotkeys
- only standalone emulators are included in the Games section
- the RetroArch section contains links for every supported system
- Apps are translated to english (Commander, SDL PAL)
- preconfigured path and emulators for every supported system
- a subset of the libretro cheat database for every supported system
- You should first update your Miyoo Mini firmware to the latest update. Updates can be downloaded from https://lemiyoo.cn/upgrade/, and a guide on the flashing procedure is found on https://media.discordapp.net/attachments/891336865540620338/931055123654905898/Miyoo_Upgrade.png. As of writing the latest update is 20220108 (January 8th 2022). It may work on other firmware version but I haven't tested it.
On a freshly FAT32 formatted SD card, copy the contents of the release package to the root
-
on your SD card, backup the following folders:
App,Emu,RAppandRetroArch(located at the root) -
specifically, your saved states are found in
RetroArch/.retroarch/statesand your saved games are found inRetroArch/.retroarch/saves -
then completely wipe
App,Emu,RAppandRetroArchfrom the root of the SD card -
copy the contents of the release package to the root
- wipe
App,Emu,RAppandRetroArchfrom the root of the SD card - copy the contents of the release package to the root
For obvious legal reasons, neither bios files nor roms or box art are provided in the release package, you should copy them yourself.
Bios files should be copied to the roms/bios folder on the SD card. Create it if it does not exist.
Roms should be copied to the roms folder on the SD card. Create it if it does not exist.
The shortcuts in the RetroArch folder are configured with the following paths (you need to edit config.json files if you'd like to change them):
- Arcade - CPS1:
/roms/cps1 - Arcade - CPS2:
/roms/cps2 - Arcade - CPS3:
/roms/cps3 - Arcade - Fina Burn Neo:

Some game ports are supported by RetroArch cores. The data files should be copied to the following folders:
- Doom:
/roms/doom - Quake:
/roms/quake
The following cores are used by default:
- Arcade - CPS1:

Some alternative cores are available in RApp/backup, if you want to try them. Simply move the relevant folder up one level.
All cores can also be loaded directly from the RetroArch frontend (App/RetroArch).
Box art should be copied to the boxart folder on the SD card. Create it if it does not exist.
Given the small size of the screen, 2D box art works the best. In any case, images should be png format and have a maximum width of 256 pixels.
The shortcuts in the RetroArch folder are configured with the following paths (you need to edit config.json files if you'd like to change them):
- Arcade - CPS1:
/boxart/cps1 - Arcade - CPS2:
/boxart/cps2 - Arcade - CPS3:
/boxart/cps2 - Arcade - Final Burn Neo:

If you have subfolders in your ROM folders (for instance, I like to have subfolders per genre), the images should all be at the root of the boxart folder.
For all RetroArch cores, the following hotkeys are preconfigured (you can change them in the RetroArch setting though, if you want another setup):
NB HK refers to the function button (small round button just below the screen)
- Open or close RetroArch menu:
HK + X - Save state to the current slot:
HK + R1 - Load state from the current slot:
HK + L1 - Increment save slot:
HK + dpad right - Decrement save slot:
HK + dpad left - Toggle fast-forward:
HK + R2 - Rewind:
HK + L2 - Exit RetroArch:
HK + select
Note that pressing F does not bring up the menu anymore, as it is used as the hotkey enable button.
