I have no insider knowledge on this so everything I said is hearsay based on what I have read. The Mist AGA core became available and usable very quickly considering there is limited hardware information about AGA (no AGA Hardware Reference Manual like for ECS). Look at the effort to reverse engineer and document the Amiga chipset with Clone-A and even hooking a 1200 up to analysers currently for the FPGA Arcade. Granted, there have been stealth projects like the AGA MiniMig and Natami which did a lot of work under the radar before surprising us with how far they had progressed. Either someone really knew what they were doing with Mist AGA or they had more than a peak at some version of the MiniMig AGA core.

I am 95% sure they are different code bases.
They are almost certainly different code bases now .
