Yeah, I'm actually pretty sure that developers from the year 2000 discovered a time machine, went back to the 80s, and developed this thing.
So far, my best is a measly 700k-- hoping to improve!

I'm also very pleased with how good of a job Hamster did porting or emulating it on Switch. By default, the pixels are crisp, there's no input lag that I noticed, and no jitter or ripples in the scrolling (I'm on a 720p display, if that helps). Even when zooming to fill the screen in vertical mode, it gets slightly blurred (naturally) but it still moves smooth as butter. It's quite the contrast to the Capcom Beat 'em Up pack I got, which seems to be laggy even in single player and a bit harsh on the eyes when blown up on a big LCD monitor.
