Here is what I have pieced together so far. The project I am working
on has succesfully burned a couple of CD32 discs, but I have not
created my own, so some of what follows may be incorrect assumptions
I have made. But I think it will help give you an idea of the
process.
You should be able to burn a CD-ROM with PC files and Amiga files. You
could put a disk.info file in the root for Amiga users and something
like install.pif file for Windows users to install from Windows. I
have read the Fish & More Amiga disc from a PC and it contains a
disk.info.
To make a CD-ROM, you will need to get CD-ROM premastering software.
This takes your files on disks and makes a single "disc image file"
from them. This file contains all the data laid out in the order
that it will go on
What you will want to do is contact CATS to get signed up as a
developer and get the CD-ROM premastering software. This will allow
you to generate the disc image file. One of the reasons for using
the Amiga for burning the disc is that you will be able to use PC and
Amiga files. If you do it with PC premastering software, you
probably will be limited to the 8.3 character names.
The Amiga premastering software sounds very good. It allows you to
generate ISO 9660 level 2 discs, use longer file names, and supports
the Rock Ridge extension protocols (deeper than 8 level directory
hierarchies?).
Make sure you ask CATS for the driver which lets you use the image
file as an AmigaDOS volume. This is important because it allows you
to do a LIST ALL of the files in the image to make sure you created a
correct ISO 9660 disk image and test your prototype before you get
the disc made.
If you want to connect a writable CD-ROM burner to your own computer
and make the discs yourself, then you will need to get CD-ROM
"mastering" software. I'm not sure if Amiga based mastering software
is available on the Amiga. I'm pretty sure that the premastering
software from CATS will also master, but I don't know for certain as
we don't have a CD-ROM burner yet.
You will probably just want to make an image file and then send it to
a CD-ROM burning service bureau. CD-ROM writers are still $3K or
more. You can post a message in the PHOTOCD forum asking for
information from CD-ROM writing service bureaus.
CATS will also burn CD-ROMs, but I think they are only burning CD32
discs for commercial applications. You send them a 2 GIG DAT tape
with the image file. You can also append an archive of the original
files used to build the image. This can serve as a backup in case
something is wrong with the image file. CATS can accept tapes
archived with Quarterback or Ami-back.
For other CD-ROM service bureaus, you will have to ask them how they
want the image file on the tape. Most will probably be able to take
a TAR file. To make a TAR file on a DAT Tape, you will need to get a
SCSI Tape handler and a version of TAR. Both are available here in
the Amiga libraries.
Well, I'm still trying to figure all this out for myself. So if
anyone can jump in here, I'd appreciate it.
