This is the list for currently supported MS-DOS games. You shouldn’t need any configuration to run these games, you only need the files and use the name in the code column as the folder name.

This is an example of a valid ms-dos game folders

retrox/dos/alone1/
retrox/dos/coolspot/
retrox/dos/gods/

Note the use of the names like alone1 and coolspot, according to the table those codes will help RetroX detect which games are, and it will use the configuration that was already tested for RetroX.
