Features

BIOS
BIOS romsets are not required when using "Full Non-Merged" arcade romsets. For "Split" and "Non-Merged" romsets, place the necessary BIOS in the same directory as the game romset.
Note:
Place the bios in the directory:/recalbox/share/roms/mame/
or in its subdirectory if you use several Mame cores, for example:/recalbox/share/roms/mame/
Games and their bios must be in the same directory or sub-directory.
¶ 
Roms
Libretro-MAME is based on the latest versions of the MAME emulator and the game catalog is extensive.
Click here to get more info about Mame development.
- Based on romset: MAME 0.258 (August 30, 2023) Non-merged
- DatFile: You can find the dat file in your recalbox at location
/recalbox/share/arcade/libretro/mame.dat.
¶ Supported extensions
Roms must have the extension:
- .zip
- .chd
CHD files are only needed for certain roms. If there is no CHD file for a rom, the rom will work.
¶ Location
Put your roms like this:
┣ 📁 recalbox
┃ ┣ 📁 share
┃ ┃ ┣ 📁 roms
┃ ┃ ┃ ┣ 📁 mame
┃ ┃ ┃ ┃ ┣ 📁 game
┃ ┃ ┃ ┃ ┃ ┣ 🗒 game.chd
You can also opt for a subdirectory (useful if you want to have a mame set for another core).
┣ 📁 recalbox
┃ ┣ 📁 share
┃ ┃ ┣ 📁 roms
┃ ┃ ┃ ┣ 📁 mame
┃ ┃ ┃ ┃ ┣ 📁 Mame
┃ ┃ ┃ ┃ ┃ ┣ 🗒 game.zip
