I just got my first DMG today and I gotta say it has aged VERY well given the age
they look way worse on camera than in person. In any moderate indoor lighting it will be very clear.
It actually performs better in low light than I remember my GBC doing.

I've never seen "ghosting" either, and I know what that looks like given how god awful passive matrix laptops were in the mid-90s.
There's some motion blur of background elements when moving fast, but the player in the center of the screen is always clear and no projectiles/etc really blindside you like I expected

overall a much better experience than I expected
