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.

It would be lovely if it got more support for disk images of various sorts, and even QL successors, but it appears there aren't that many people around to contribute to such a project.


I suspect you don't have I/O Card...
Without it (Mister I/O Card 5.5 XL) you miss the second SD reader where you should install qxl.win

So far everything work fine, Mister is about 2.5 faster than a bare QL. In the setup you should leave CPU to normal, if you try to use x2 or x4 doesn't work.
Try to attach some picture.
