Marcel, I could happily test your suite even if unfinished, if possible.....
No need to test it, as the CPU exhibits spurious faults I know it's broken in the worst way and any test is meaningless. Also, my version doesn't have the HDMI scaler as I don't have the license for that.
In the meantime a free scaler was released and another cycle accurate 68k core was revealed for another core, maybe I will try these one day.

Cheers, Marcel

Are you referring to the FX68K core? I had a brief look, but was not in the mood to manually convert System Verilog to Verilog, which is required for my synthesis tools.

The FX68K core seems interesting to replace a GoldCard (not SuperGold Card), eliminating the need for software changes.

Yes, that's the one. My toolchain can handle SystemVerilog, but no idea how easy it is to exchange the cores, I haven't yet have any look at them.

Fabrizo, Marcel,

Stupid questions first, did you check the ".QSF" file for the SD card pin assignments?

I haven't had a chance to check the ".QSF" against my DE2-115 but am sure that changes will be required.

I have a DE-10 nano, which is the intended target board. So, no, it's fine for me.
