Whats that for exactly a new mist core or something ?

Well MiSTer*, but it means there's finally cycle exact VHDL implementations.

That sounds wonderful!

I'm very curious what this could mean to the future of the STF Remake Project.

I'm not really sure, because the suska ones were direct replacements for chips, MiST doesn't have a lot of signals as its all internal, so you can't really use these cores (AFAIK) with the stuff I am doing.

In case of the STF, its uses a real CPU, and other chips are locked into 8MHz clock, so even if the cores are not 100% timing wise, it probably won't matter.
