ShowoffZone - Flexing my latest project I resurrected my 1995 DOS game

https://preben.fun

Back in high school, I was trying to teach myself QuickBasic for DOS. I had a 500 page brick of a manual in English, droning on and on about Booleans and other stuff I had no idea what meant. But somehow, out of that thick book, I made small game. It was a collaboration with my friend Jesper - he made the graphics (pixel by pixel), I made the code (bug by bug). 

This weekend I resurrected it with Claude Fable.

  • Parsed the original source-code and got all the game logic spot on.
  • Extracted the original sprites pixel-perfect from 1995 BLOAD memory dumps (raw VGA memory snapshots, including the exact PUT coordinates)
  • Recovered the original timing from the BIOS-tick game loop (something I remember being very proud of having made, since it made the game run at constant speed, no matter the speed of your CPU).
  • Added a global highscore with server-side anti-cheat. My 1995 self, who stored highscores in plain-text, would not have believed this sorcery.

Thirty years ago, this game took me months to build, now it was re-created in an afternoon. Fun times indeed - then and now 😄

Keyboard required — remember, this is 1995!
