Have found the place to download the CD32 developer file from here:
https://www.amigapd.com/cd32-toolkit-manual.html
I think even linking to file in program would raise issues.
ISOCD-Win:
If you have TM file, you can upload it to the c:\Users\Public\Documents\Amiga Files\ISOCD-Win\ directory, and if you don't have it, the program will try to find it on the Internet. The program does not have this file uploaded for licensing reasons.
The CD32_DeveloperKit package has this file because it was for developers.
Thats all I needed to know, will give it a go. As I have a CD creation setup on Amiga, which optimises images.
Be nice to do it in windows, without running through Amiga.
