Put your bios like this:

Libretro Flycast is based on the Romset of MAME but also on NullDC formats for its Atomiswave part.
Roms must have this extension:
Only Atomiswave roms from a RomSet MAME 0.135 or higher are compatible.
We recommend the RomSet Mame 0.235 which will bring a lot of additional compatibilities.
For more information on the current RomSet version, see the [MameDev] page (https://www.mamedev.org/release.html).
To sort your arcade roms, the dat file is available in the folder:
/recalbox/share/bios/dc/
Put your roms like this:
┣ 📁 recalbox
┃ ┣ 📁 share
┃ ┃ ┣ 📁 roms
┃ ┃ ┃ ┣ 📁 atomiswave
┃ ┃ ┃ ┃ ┣ 🗒 game.zip
These roms are compatible with Flycast but less reliable than roms from a MAME set.
The NullDC roms are in the format :
.bin + .lst
.
Put your roms like this:
┣ 📁 recalbox
┃ ┣ 📁 share
┃ ┃ ┣ 📁 roms
┃ ┃ ┃ ┣ 📁 atomiswave
┃ ┃ ┃ ┃ ┣ 📁 game
┃ ┃ ┃ ┃ ┃ ┣ 🗒 game.bin
┃ ┃ ┃ ┃ ┃ ┣ 🗒 game.lst
To be able to keep your custom configurations during an upgrade, we advise you to use our configuration override feature.
You can configure various options in two different ways.
