I had both and played the daylights out of Omega Race.
It was addictive, especially with game paddles. I think the VIC 20 version was even better than the arcade version.
Now I’m thinking of those early computer magazines that would publish screen shots so readers could prove they had gotten a high score on a game. Just think of that — you would take a picture, take it somewhere to have it developed, pick it up a few days later, snail mail it in, then maybe you’d see it a few weeks later published in a pulp paper magazine. Talk about old school.
Oh yeah, I played the snot out of Omega Race too. Went so far as to wire up a 555 circuit with potentiometer inline with the controller for automatic missile firing.
Still only got 4 shots on the screen at any time, but there were ALWAYS 4 shots on the screen with that circuit! The pot allowed me to vary the rate at which the auto fire occurred for either tight grouping or a more spaced out pattern of the missiles.
