mkchd

chdman made easy

Usage: mkchd CUE_FILE
   or: mkchd CHD_FILE

Converts a CD to CHD format compressed with zstd + FLAC. The hunk size is also reduced from 8 to 4 sectors, which is required to decompress quickly enough for x8 CD speed on MiSTer FPGA. The input file(s) will be removed (if BIN/CUE) or replaced (if CHD).

chdman v0.262 or higher must be in your PATH.

Environment variables

• TMPDIR: directory for temporary files (default: /tmp)

Examples

Compress a bin/cue disc:

mkchd "/path/to/Disc.cue"

Recompress a CHD:

mkchd "/path/to/Disc.chd"

Convert all discs in the current directory:

for file in *.cue; do ${script_name} "\${file}"; done

Convert all discs in the current directory and subdirectories:

find . -name '*.cue' -execdir ${script_name} '{}' ';'
