Nintendo of America often used pixel art for their own box art early on in the NES era. It was similar to the in game graphics, but usually more detailed. See Metroid’s original artwork. If there was a requirement for third parties, perhaps it could be met by simply including screenshots on the back.

The hardware they run is different, but the approach is the same in that FPGA and low level emulators both aim to accurately emulate the console hardware itself. You could theoretically reach 100% accuracy with either method. My problem with Analogue’s “no emulation” claims, is that they mislead people into believing their products are perfect recreations and that software emulation is inherently inaccurate. Due to being reverse engineered reproductions, Analogue’s core still encounter similar bugs that are seen in software emulators and need to be patched.

Analogue’s marketing really wants to push this idea, but FPGA is emulation. It just uses a low level approach for cycle accuracy. This is similar to software emulators that focus on accuracy, like BSNES.
