Universal instructions

• Download the version number according to your Mame romset version
• If your version isn't released yet choose the closest version
• Put the bat file in your Mame roms folder
• Run all bat files one at a time
• Delete the bat files as they're now useless
• Find newly created directories like "_naomi"

*Note that this doesn't move your roms in the folders. This safely create a copy of your roms in a new folder.

Launchbox specific instructions

• Create a new emulator for example "Demul"
• Create a new platform with custom name
• Add roms from the "_board" folder the bat file just created
• Quit Launchbox and go to LaunchBox/Data/Platforms folder
• Find the associated platform .xml file and open it
• Find and replace all your "YOUR CUSTOM PATH" without quotes
• Replace with your Mame folder "Games\Arcade" without quotes
• Delete the "_board" folder with useless roms

*If you want to keep your roms in a different folder than the original Mame folder, which I don't recommended to, don't forget to copy the CHD folder that's associated with your rom. The bat files aren't meant for you to put the games in a different folder so yes this is manual and will take some time. For compatibility issues and saving your disk space we recommended to leave all the Mame roms and the same folder.

*This works no matter if you're using a merged, non-merged or split romset.
