Roms
¶ Supported extensions
Roms must have the extension:
- .nes
- .unf
- .unif
- .zip
- .7z
This system supports compressed roms in .zip/.7z format. However, be careful, it is only an archive.
The files contained in the .zip/.7z must correspond to the extensions mentioned above.
Moreover, each .zip/.7z file must contain only one compressed rom.
¶ Location
Put the roms like this:
┣ 📁 recalbox
┃ ┣ 📁 share
┃ ┃ ┣ 📁 roms
┃ ┃ ┃ ┣ 📁 nes
┃ ┃ ┃ ┃ ┣ 🗒 game.zip
The roms using No-Intro format are highly recommended.
