NAME¶
chdman - MAME Compressed Hunks of Data (CHD) manager
SYNOPSIS¶
chdman option
DESCRIPTION¶
chdman is the (C)ompressed (H)unks of (D)ata (CHD) manager for MAME. It is a tool to manage CHD images.
OPTIONS¶
Please note that each option allows a set of switches, the meaning of each is explained in the SWITCHES section below. Whenever the short form for the switch is listed, the long one may be used instead.

- Copy all hunks of data from one CHD file to another. The hunk sizes do not need to match. If the source is shorter than the destination, the source data will be padded with 0s.
- addmeta -i filename -t tag [-ix index] [-vt text] [-vf filename] [-nocs]
- Add metadata to the chd.
- delmeta -i filename -t tag [-ix index]
- Remove metadata from the chd.
