Kickstart 3.9 is instead is a custom 'scene/homebrew' ROM created by the Amiga community for use with AmigaOS3.9.Īlthough AmigaOS 3.9 boots fine using a Kickstart 3.1 ROM, before AmigaOS 3.9 actually loads it normally first needs to patch the system by running setpatch to add the additional AmigaOS ROM Updates required for 3.9, and then once they are loaded/patched the system reboots and then loads AmigaOS 3.9. There wasn't an official Kickstart 3.9 ROM released by Commodore, or any other Amiga company.
