A common mistake is dumping everything into one folder. Create the following hierarchy: full mame roms install

C:\MAME\
    ├── mame.exe
    ├── roms\          (all game ZIP files go here)
    ├── chd\           (each CHD game in its own subfolder)
    ├── samples\       (audio samples for older games like Donkey Kong)
    ├── artwork\       (bezels and scanline overlays)
    ├── ctrlr\         (controller mapping files)
    └── ini\           (configuration settings)
