> they better choose MiSTer FPGA from the beginning.
Well, the MiSTer project was yet 4 years from being launched back in 2013 when the RISC-5 was implemented in FPGA, so I hope you'd excuse Wirth from not choosing it.
And shortly after Wirth launched his RISC-5 system, the original FPGA board went out of production.
