FPGA is technically emulation but not in the same sense as BSNES. BSNES is software emulation, requires a beefy computer for complete accuracy. The SuperNT gives perfect accuracy on a less than 2GHz ARM processor by using the exact same chip logic as the original Snes, so it theoretically is a SNES. BSNES using reverse engineering with its own code to emulate snes hardware onto x86 architecture. Analogues marketing is fine the way it is because they are correct in what they advertise, the product is niche and targets retro collectors with physical collections.
