To dispel the inherent "100% accuracy" for FPGA cores, here are some discord quotes from FPGAzumSpass himself about the N64 specifically (and the rest of 5th gen consoles for than matter):
So a perfect, 1:1, 100% accurate N64 core would need "all details known" which is exactly what i was saying all this time about FPGAs not being magic and needing the same information and resources emulator devs also need to accurately emulate each system. And apparently, knowing all the details of how 5th gen machines work is "near impossible". Which also explains why we still don't have 100% accurate PS1/SAT/N64 software emulators yet either.
And on top of that, he suggests a perfect N64 core would need an FPGA chip that costs 4k. Which i didn't know it would be so high.

to think about. Just because something has "100% compatibility" and "can play all games to completion" doesn't mean it's "100% accurate". Or even "99.9%" for that matter. Even old Mupen forks could have 100% compatibility with some tinkering and that's a highly inaccurate HLE emulator.
This whole thing about how FPGAs are so much more accurate than Emulators, etc, started as marketing talk from Analogue when they were selling the NT. It's just overhyped advertising stuff meant to sell more products to a casual crowd who need something that "just works". That's why Analogue always used HLE emulators and cheap Pi devices as comparisons but always ignored the accurate emulators on more powerful PCs that even helped them develop their SNES FPGA core. Yeah, they forgot to mention this in their ads.
Watch them do the same exact thing with their upcoming N64 device. They will compare it to old PJ64 and Mupen emulators in Pi4 or Pi5 using GlideN64 and will never mention Ares, Gopher or Parallel. They will ramble about how "N64 emulation sucks" ignoring all the advancements the last 10 years. They will even mention the good old "Mario Kart Jumbotron" effect. Quote me on all that.
Fact is, FPGA and software emulators have their own advantages and disadvantages, but accuracy is not an exclusive thing for either. Let's just stop with this myth already.
There are FPGAs with enough internal memory for RDRAM, but super expensive. Otherwise you need external RAM that really fits the needs to be able to reach 100%.Still, the design must be perfect and all details known, what is near impossible with gen5
N64 would need 9Mbyte for RDRAM if you want the expansion pak.List price for FPGAs offering this is around 4k$ for AMD and 7k$ for Intel.Even in high volume with 20% of list price this is still expensive
