A useful piece of advice: (CHD Manager) is a command-line tool included with MAME (and stand-alone builds) that converts disc images (like .cue/bin , .gdi , .iso ) into the CHD (Compressed Hunks of Data) format—saving space while remaining usable in emulators.
chdman createhd -i "image.img" -o "image.chd" Always verify CHDs afterward with:
chdman createcd -i "game.cue" -o "game.chd" For :
chdman verify -i "game.chd" Would you like a full list of chdman commands or help converting a specific format?
