Afaik, you can't share those in here, unless I'm wrong ?This makes no sense.
All source ports require you add the ROM/game data.
Quakespasm requires you to add the .pak files
DiabloX requires the game data
Descent requires the game data
Duke Nukems eduke32 requires the games .grp files
GZDoom requires .wad files.
Serious Sam, Open Morrowind, Rollercoaster Tycoon, Cannonball (outrun), the list goes on.
This is standard.
