CD-ROM discs can hold up to 640 MB of information, which must include:
The title's program and art files
System files
CD-ROM access information generated during the CD layout process
In most cases, your title can use approximately 600 MB on the disc. The
exact portion of the 640 MB for your application data is variable and
depends in part on these factors:
How much space on the disc does the system require?
How large are the individual developer files?
How many avatars (instances) of the root, label, and directory files
does the layout tool place on the disc?
Default numbers are: 3 directory avatars, 7 root avatars, and 2 label
avatars. The cdrom.tcl file contains information on how to safely
change the defaults.
The only reliable way to determine exactly how large an application can
fit on the disc is to run through the normal layout procedure described
briefly below and in detail in the Preparing Simple cdrom.image
Files:
Place the executable and data files in the /cdrommaster/takeme
folder
Set the cdrom.image file size in the cdrom.tcl file to
640
Run the layout tool
You can include the maximum amount of data when, in the cdrom.tcl
file, image file size is set to 640 and the number of directory, root,
and label avatars are all set to two. If you do this and the layout tool
produces the error "Could not assign avatars for ...," you need to reduce
your title's content.
