An FPGA seems like a lot of effort, but an SNES emulator running on a Raspberry Pi seems like it may have been a better option IMO.

I am sure that Nintendo is using FPGA for internal R&D, so they have people capable of writing cores for FPGA. Add to that the fact that Nintendo has all the schematics and detailed information about the original hardware and designs.
Yes, a FPGA would have been work, but not lots of work for them. And we are speaking of 8 and 16 bit hardware, that is very small and limited hardware.
Besides that: Windows can run on a Raspberry PI, so maybe the emulator on Windows used by Nintendo is already using that. Who knows?
