the good news about Virtual Boy™ – Nintendo Classics is that it does indeed use a pixel‐perfect display mode on both consoles (yes, this means the pixels are significantly bigger when using an original Nintendo Switch). the lenses do blur the edges a bit, but it’s still a good image.
the bad news is that it inconceivably doesn’t use VRR to run the Nintendo Switch 2’s screen at 50 Hz, instead smearing those frames across the usual 60 Hz.

the wildest thing about Nintendo not using VRR to run the Switch 2’s display at 50 Hz with their Virtual Boy emulator is that even the Switch 1 can do this. 50 Hz is well within the safe range for underclocking its display.
anyway i have RetroArch running on my Switch 1 at 50 Hz now. the Mednafen‐based VB core recently added an eye separation option for use with Nintendo’s VB hardware. i really hate wrestling with RetroArch’s UI, but once you wrangle it into shape it does actually work well.
my hot take on the Virtual Boy library is that Virtual Lab is a better game than Waterworld.
both have bullshit difficulty scaling, but at least i can do satisfying plays in Virtual Lab by clearing big structures and setting up combos. Waterworld is just all BS all the time.
the only points Waterworld gets is for better music. it might be more “graphically advanced”, but it has no charm. and it might have “more responsive controls”, but your craft’s acceleration is so abysmal it doesn’t matter
