Feature request: Backport FX68K core from MiSTer to MiST #17

Open egrath opened 1 month ago

egrath commented 1 month ago

The MiSTer for of Minimig uses the FX68K core instead of TG68 for cycle accurate CPU reimplementation when running in 68000 mode. Would it be possible to backport this feature to upstream to have it on MiST and TC64 too?

The commit in question is:

It's a nice idea, but the FPGA on MiST is too full to take the FX68 as well.

It would be possible to build a separate core using FX68 instead of TG68 - but there's so little software that fails with the current CPU core that it's a lot of effort for not a huge amount of gain.

If you want to persuade me otherwise, feel free to list any software you know of which would benefit!
