More Information
To load a MAME arcade game, you typically need to place the CHD file in a directory has the same name as the ROM's filename prefix (some emulators use a single generic directory for all CHD files). For example, for a ROM with the filename mygame.zip, a CHD file named mygame.chd, and a ROM directory Roms, emulators commonly use the following convention:
- /Roms/mygame.zip
- /Roms/mygame/mygame.chd
