>Afaik MiSTer cores can't run on open source hardware or compile on open source toolchains. It is on a core-per-core basis e.g. I managed to run some cores on ECP5 as well as GW1N, using open-source synth/route tools. There's also some effort to make it FPGA family independent. It is not hopeless; we will get there.
