I recently got a build of the Minimig Amiga core running on IceSugarPro (which has the same FPGA and same size SDRAM) - only the ECS chipset (no AGA) but I did get RTG graphics working at 1280x720x16bit. It uses PS/2 rather than USB for keyboard and mouse, but apart from that it would be trivial to port to this new board.

I found this one so far:

Exciting to have an alternative to de10-nano, especially seeing the price doubled? since I got mine.

Amazing project anyway, and brings back dreams of building some arcade cabinates. Icepi Zero looks perfect for the job! I hope they arrive in the EU one day.

it probably can - I see that uls3x already has a few ported over cores, and they will be able to run on this fpga with little modifs
