(source included in the link, writeup will follow) To my knowledge, the first implementation ever in 32 bytes. This builds upon the 65 bytes version of Vladislav Kaipetsky, Tenie Remmel and Mark Andreas from 1998.

The modbyte trick is clever. The writeup sure brought back memories. Over 20 years ago I made a 2-player graphical worm game for DOS. I still have it in a zip. It is 123 bytes long and back then I couldn't squeeze more out of it. After reading that writeup I feel like there's so much bloat in that 123 bytes!

    I can make it available here :) Here's the binary: uBMAzRC6AKCOwovyM/+xAYvp+rraA+yoCHX77KgIdPsmgDWRdDCQkORgityyBDqHawF0C5CQ/sP+ ynXy6wmQKtzQ44uPcwED+YD0BIf+h+k793W/tAyA9ATA7AKK1IDCQbgDAM0QtALNIcMeIBEfJCYX Jf//AQDA/kAB Copy that to a file and then: "base64 -d blah.txt > worms.com" Make sure there are no spaces in the beginning of the lines. This is from the original document: "This is a version of the worm game for two players. Game objective is to stay alive longer than the other worm! You die if you eat yourself, ie. you are going RIGHT and you press LEFT. Move the worm with the following keys: PLAYER A: (topmost worm) W A D S PLAYER B: (lower worm) I J L K Winner is indicated by player letter, "A" or "B". An even game is indicated by a "C". An even game means that the worms ate each others heads, and nobody won." Edit: correct base64 formatting

  I did the same thing! The year was 1997. There was some kind of online coding competition back then if I recall correctly. Mine is larger (256 bytes) but it has a nice background image (a mandelbrot fractal).

      Not sure why, just tested it in native dosbox and it works. edit: try pressing any arrow key when the fractal is drawing. ~controls : Player 1 Player 2 (or arrows) W 8 A + D 4 + 6 X 2

      This is so interesting, VM using a URL for the code.

        A bit of hair splitting, but technically it's an emulator, not a VM, since it's just simulating the CPU using javascript in your browser.

I have to say, you really are an amazing coder. I read your write up for “memories.” a few days ago and it completely blew my mind. Thanks for sharing your knowledge!
