∆[-f∆DOSAUDIO.PAT][ENTER]
VCDUTL Runs VCDUTL.
TSTGAME Project name used to create the CD image
that is being updated.
ISO1FILE.DDD ISO file name that contains the DOS file to
be updated.
DOSAUDIO.D01 The name of the DOS file to be updated.
DOSAUDIO.D02 Replacement DOS file name.
Options
-f Option
Name of the update data file used to replace the DOSAUDIO.PAT DOS file (can be a
user specified file name).
When this option is specified, the CD image itself will not be updated. This
update data file will be used during emulation.
If this option is not used, the CD image itself will be updated without the update
data file being output.
There are two methods for editing multiple DOS files for one CD image:
(1) Commands are executed repeatedly with the
-f option.
(2) Commands are executed repeatedly with the
-f option without
changing the update date file name.
Note that the CD image remains in an unchanged state with method (2).
Check Items
When the -f option is used, an error will occur if the ISO file containing the speci-
fied update DOS target file is channel-interleaved. After the error occurs, the com-
mand will terminate without any further processing.
When the
-f option is not used, an error will occur if the DOS file size is unsuitable.
