Specifies a single directory where memory card files are stored. Memory card files store the contents of removable memory cards for systems which used this type of hardware. This data is read and written under control of the user via the “Memory Card” menu in the user interface.

The default is memcard (that is, a directory memcard in the same directory as the MESS executable).

If this directory does not exist, it will be automatically created.

mess -memcard_directory <path>
