I've been known to (re)play old games---sometimes in new engines, sometimes on original hardware. The latest games to fit that bill are Duke Nukem 1 + 2 as part of the Duke Nukem Evercade Collection 1 where an amazing feat was pulled off by completely rewriting the engine to support smooth scrolling on the Evercade widescreen handheld. If you press SELECT, you can switch between classic and modern modes, neatly highlighting the improvements. Here's a video I recorded for the review I wrote showcasing the effect:

The original source code has been lost for decades, but the initial DOS release never played smooth anyway: early PCs were never known to handle 2D sprite-based games as well as Nintendo's (S)NES family.

Hopefully Blaze Entertainment wants to keep on pursuing the direction of Apogee game remakes. I know I'll buy them in a heartbeat. But what games from my youth are already remade/remastered? I decided to compile a non-exhaustive list for my fellow 80486 comrades; in case they would be willing to play any of these without that yellowed mechanical keyboard and DOS prompt. For me, the joy of using the original hardware is part of the gameplay fun, but sometimes, I just want to waste a bit of time from my couch using whatever handheld device lies nearest. Besides, these remakes introduce a whole new audience to the great olds of yore.

Let me know if I missed big ones. Wikipedia houses a game engine re-creations and a remakes and remastered listing, and I found this awesome game remakes list on GitHub, but I'm only interested in DOS games and preferably proper remakes instead of source ports (emphasized in bold).
