Description

This function obtains and returns the volume attribute of the ROM or RAM area. The volume attribute, which is represented by u8-type bits, can have the following contents.

MFS_VOLUME_ATTR_VPROTECT_WRITE	0x20	Volume write protected
MFS_VOLUME_ATTR_VPROTECT_READ	0x40	Volume read protected
MFS_VOLUME_ATTR_WPROTECT	0x80	Write protected

When the MFS_VOLUME_ATTR_VPROTECT_WRITE bit is 1, it indicates that the disk is write protected from other games. The disk can be written to only when the company code and game code specified by the mfsInit*() or mfsSetGameCode() function match the company code and game code written in the system ID area of the disk.

When the MFS_VOLUME_ATTR_VPROTECT_READ bit is 1, it indicates that the disk is read protected from other games. The disk can be read from only when the company code and game code specified by the mfsInit*Boot() or mfsSetGameCode() function match the company code and game code written in the system ID area of the disk.

When MFS_VOLUME_ATTR_WPROTECT is specified, the disk is write protected from all games.
