Yes, and quite limited. The MiSTer hardware, and other similar platforms are good for emulating ancient video game processors and running 8-bit style video games. This is a fun thing to do I guess if you like that. Modern high performance FPGA's, meaning AMD/Xilinx since that is the only option, can handle prototyping modern CPU's, including RISC-V, as soft processors. This is great for R&D, but FPGA's have hardware ARM cores built in, specifically because they are much more efficient and have existing ecosystems. There are other options for hardware RISC-V CPUs, but not really a SoC style FPGA+RISC-V combination. that I am aware of.
