For the thousands of people in the MiSTer FPGA ecosystem, some of whom bought the hardware [0] as long ago as 2020, for well under $200 (it's more, now [1]), a featureful FPGA N64 core - developed by Robert Peip, who is paid, most would say very deservedly, thousands per month via P_treon) - will be coming soon as a free update, once the already very advanced work is complete. The betas are playable now, and there are near daily updates.
