We’ve spoken about this before, how the non-backlit handhelds like GBC, GBA, GBA SP (frontlit model) had very good motion clarity, with moving objects and backgrounds not smearing or ghosting.
Good to see a video delve into this topic a little more, though I’d love to see GBC added to the mix as I remember it being good but my childhood handheld no longer switches on.
I’m surprised he doesn’t have an answer for 3DS playback of GBA games featuring frame blending given his look at GBA displays, though.
