I played this on the Atari 800. My dad and brother somehow wrote mods for the game to do things like make Rockford invulnerable, or make it so that Rockford could dig through anything (solid walls, boulders, slime, etc).
I think they learned how to do the mods from a computing magazine to which my dad had a subscription. I remember this magazine would have whole programs printed in it that you would have to type by hand. My memory is fuzzy as I was very young, maybe 7-years-old. I'm not sure if the mods were typed out in the magazine, or if it just gave the general theory and they figured out the rest.
