Command Line

CHDMounter.exe [/l] [/a] [/s:<alias>] <chd_file> [mount_point]

Argument	Description
/l	Open the mounted drive in the file manager (Explorer/Finder/xdg-open)
/a	Auto-select a drive letter, even when a mount point is given
/s:<alias>	Select the console/format by alias (e.g. ps2, cuebin2352)
<chd_file>	Path to the .chd file (required)
[mount_point]	Drive letter or folder (optional; auto-picks if omitted)

Notes

• Arguments can be in any order.
• Flags are prefixed with / and are case-insensitive.
• A console alias may also be passed as a positional argument: CHDMounter.exe game.chd ps2.
• On Linux and macOS the executable is named CHDMounter (no .exe suffix), and mount points are always directory paths.
• If no console type is given, a dialog appears asking you to choose.
• Numeric console indexes are not supported — use aliases (see Console Types).
• If the folder form is used for mount_point, it is created if it does not exist.
• /a wins over an explicit mount point: CHDMounter.exe /a game.chd M: mounts at the first available drive letter, not at M:.

Examples

:: Mount a PS2 game as drive M:
CHDMounter.exe /s:ps2 game.chd M:

:: Mount an Xbox 360 game, auto-select drive letter
CHDMounter.exe game.chd xbox360

:: Mount a Dreamcast game and open Explorer
CHDMounter.exe /l /s:segadreamcast game.chd

:: Mount as a virtual CUE/BIN image (2352-byte sectors)
CHDMounter.exe /s:cuebin2352 disc.chd

:: Mount with the generic ISO 9660 parser
CHDMounter.exe /s:iso9660 data.chd N:

:: Mount a PS3 image as a single image.iso file (for RPCS3)
CHDMounter.exe /s:isoraw2352 game.chd

:: Force auto-selection even though a mount point is present
CHDMounter.exe /a /s:ps2 game.chd M:

:: Console alias as a positional argument
CHDMounter.exe game.chd ps3

Auto-open after mount

With /l, CHDMounter opens the file manager at the mount point as soon as the drive is ready. The same behaviour can be enabled permanently in Settings (Auto-open mounted drive).

Console aliases

The full alias list is in Console Types. Aliases are case-insensitive and resolved by the VideoGameFileSystemParser library, which is the single source of truth.
