We're totally serious, we may be slightly late to this one, but we're totally serious. Ed Fries, former VP at Microsoft, and according to his own biog, "Co-founder of the Xbox Project" has developed a version of Halo for the beloved and ancient Atari 2600.
"Last fall I was in Philadelphia," writes Fries, "speaking at a small video game conference. On the way to the airport I was talking about writing games for the Atari 800 in the early 80s and someone suggested that I read the book Racing the Beam
about programming the Atari 2600. It sounded cool so I did.
"After reading the book I thought it might be fun to play around with writing some of my own code for the machine. I hadn't written 6502 assembler in almost 30 years but it turns out it's pretty easy to pick up again since there are so few instructions. I wasn't sure what to write so I created a little Master Chief from Halo and made him run around the screen. Then I created an Elite for him to shoot at. At this point it wasn't my intention to make a full game. I was just screwing around."
That screwing around has resulted in, well, in Halo
for the Atari 2600, complete with cart!
