Hmm, that's an interesting question; when I think of owning an authentic, physical game I tend to hardly ever play them and really don't care about the value, so I suppose a custom-made copy would be feasibly worth my time- I know that Shantae for the GBC does indeed have those newer edition releases that WayForward created within the last 10 years or so, but still an authentic copy feels like a truly marvelous timepiece regardless of value and that special feeling would be hard to emulate through a custom creation unfortunately.
