Byuu, the author of Higan, has been quite critical[1] of the claim that the Super NT is as accurate as stated. It may be tempting to assume "FPGA = hardware recreation = perfect", but we don't have access to the original SNES schematics, so anything we recreate involves some level of guesswork. Higan has been in development for more than a decade, and literally every first party SNES game has been tested to ensure 10…

Makes me wonder if he was threatened legally.

I was not, it was a personal choice.

To me, Byuu didn't come across as dismissive of the SuperNT so much as the idea that FPGA's are inherently more accurate than software emulators. Both approaches have advantages and disadvantages. 20 known issues is significantly more than Higan's zero known issues (for the SNES emulator specifically; other Higan emulators are of varying degrees of quality and maturity). Unless you count issues like, there's a certai…

I'm not dismissing the incredible work of Byuu. I'm simply suggesting it is far easier to get cycle accuracy and correctness in an FPGA than through software emulation. Kevtris probably spent less than a year in his spare time to pull off nearly identical results with his FPGA. He also hasn't gone back to work through the known issues because of his work on the MegaSG.
