chdman extracthd -i "game.chd" -o "game.bin" Original ISO files do not support mixed-mode CDs (data + audio). If your original CHD was created from a BIN/CUE set (common for Sega CD, PlayStation, or TurboGrafx-CD), converting directly to ISO will lose the audio tracks . The resulting ISO will contain only the data track, making the game silent or unplayable.

While CHD is exceptional for saving storage space, there are numerous scenarios where you need to revert to the original, raw ISO (International Organization for Standardization) format. convert chd to iso

chdman createcd -i "input.iso" -o "output.chd" For BIN/CUE: chdman extracthd -i "game
for f in *.chd; do echo "Converting $f to ${f%.chd}.iso" chdman extracthd -i "$f" -o "${f%.chd}.iso" done If command lines make you uncomfortable, there are several GUI wrappers for chdman . The most popular is CHD GUI or NamDHC (which is just "CHD MAN" backwards with a GUI).
