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/Mame 2003/
Games and their bios must be in the same directory or sub-directory.
¶ 
Roms
- Based on romset: MAME 0.78 (December 2003)
- DatFile: You can find the dat file in your recalbox at location
/recalbox/share/arcade/libretro/mame2003.dat.
¶ Location

┣ 📁 recalbox
┃ ┣ 📁 share
┃ ┃ ┣ 📁 roms
