PSA: If your FPGA-based emulator is just based on observation, then unless it exactly replicates all the quirks of the original hardware, it is no more accurate than a software emulator, it's just inaccurate faster

Analogue describes their Pocket Boy as "not emulation based" on the product page. That annoyed me to no end.
They're not entirely wrong. If their FPGA reimplementations have the Kevtris Seal of Approval™, then they're most likely indistinguishable from real hardware in that you could wire up the FPGA as a replacement. Again, my gripe isn't with Analogue for the most part.

Isn't a hardware-based simulation still emulation? Even if it's "perfect", it's still not the same hardware, no? Or do I have a wrong definition of emulation?

If you program an FPGA to be, blackbox-wise, an exact copy of the original chip, it is not an emulator, it is a replica as I would see it. Would you call AMD's 386-compatible chips that went into boards for 80386 (and everything after that) hardware emulators of Intel CPUs?
