■ Volume definition

lead-in and 2 seconds gap, there are system area and volume descriptor set part. (Refer to DISC format standard specification)
Use to define the system area. Copies the contents of the file specified in the parameter on this line to the system area. At this time, if the file length is less than 16 sectors, 0x00 is embedded at the end. Conversely, if the file is too large to fit, an error will occur.

The volume descriptor set has the following volume descriptors:
(Refer to page 15 of DISC format standard specification)
●Primary Volume Descriptor(PVD)
Supplement Volume Descriptor (SVD)
Boot Record (BTR)
●Volume Partition Descriptor(VPD)
●Volume Descriptor Terminator(VDT)

At least one PVD must exist. Be sure to define it. Define other volume descriptors as needed. There may be more than one. If there is more than one, the later one is valid.
A definition command line is provided for each volume descriptor.
However, there is no command line to define this volume descriptor because the last VDT can be generated without any special specification. The end of the volume descriptor set definition is indicated by the presence of an .

● Command line
to define PVD * PVD is defined in the part between and .

Command line
for defining SVD SVD is defined between the and .

● Command line
for defining BTR BTR is defined between the and .

● VPD is not used with GAME-CD.

For the PrimaryVolume, SupplementaryVolume, and BootRecord parameters, specify the relative position within the session on the disk.

There is a command line for each volume descriptor field. Command line keywords represent fields and parameters represent their values.

● SystemIdentifier (PVD, SVD), BootSystemIdentifier (BRT)
∙ Specify the system identifier of the volume descriptor as a parameter.

●VolumeIdentifier(PVD,SVD)
∙ Specify the volume identification name of the volume as a parameter.

●LogicalBlockSize(PVD,SVD)
∙ Specify the logical block size of the volume with a parameter. Allowed logical block sizes are 512, 1024, and 2048.
