It will be a hard work.
MiST core is similar to Minimig - it has very special support on ARM side. It also uses many custom commands over SPI.
Although i've ported ARM part of MiST to MiSTer, this part of code was never tested and most likely requires tweaking/patching.
FPGA part will require special re-work as well since it's not generic core.
Anyway, i hope you will mange it since I never had Atari and don't know its hardware.
Yes I already noticed that this will not just be a coppy and paste task ...
My first goal is to bring up the OSD-Display using the Framework. I think therefore I need to create and wire a instance of video_mixer (which will not automagically be created by the Framework).
This should at least remove those warnings (that probably prevent the OSD from working):
Warning (10034): Output port "CE_PIXEL" at mist_topde10n.v(28) has no driver
Warning (10034): Output port "VGA_DE" at mist_topde10n.v(39) has no driver
Probably Newsdee has similar problems with his core, because in the porting guide is not noted that video.sv (ZX-Spectrum) has some adaptations that are needed too. Newsdee, did You check for Warnings like the ones above? I think they can not be ignored.
