That is not true. There is kickstart 3.5 and 3.9 it is even mentioned on AmigaKit. it is customized and made by a person of course and then burn the kickstart 3.5 or 3.9 on a physical writeable ROM chip to be replaced with kickstart 3.1. I just want to know if someone out there actually have these customized ROM for sale because I would like to upgrade my Amiga 1200 to kicstart 3.9. It would be super cool to have that.
I've never heard that there is such kickstart available... and what is the differences between 3.1 and 3.5,3.9 ?
