As a retro gaming enthusiast, I kinda agree. FPGA emulation is still emulation and can suffer from inaccuracy just as much as software emulation does while having a lot more limitations. It can provide lower latencies and better power efficiencies, so it isn't worthless, but its a set of tradeoffs that don't make a lot of sense to me especially when you're using original media instead. Not to mention that used GB/GBC/GBA/GG are all available for a lot less than the Analogue Pocket if you're looking for an authentic experience, and if you're not then software emulation provides a lot more flexibility.
