It's super annoying when you need the v13.2.1 firmware files for your banned Erista Switch, but the sites and updater apps you normally get them from only have up to v13.2.0!
I think the Mister is cool and all, but honestly I have seen some video's exploring the difference between hardware and software emulation and the advantages of both.... I would pick software over FPGA, wouldn't mind some sort of hybrid approach but I can only imagine how complex that would be and how expensive.
