Excellent job. I wonder why this wasn't done sooner, the demand sure has always been there. Then I notice hi res graphics is in use to emulate the 1979 vector CRT, and "old" style artifacting in the U.S. looks awful on this game, on CRT'S thru the 1990s. There was no off switch for artifacting back then and Mac/PeeCee Atari emulators didn't mature until more recently, with let's say "new" artifact render style starting in 2006.
I sense the play speed wobble up and down a little but doesn't bother me. Is it a bug or feature to randomly explode when using the hyperspace command? I thought you'd only explode if you warp directly onto an asteroid, but here I disintegrate for no apparent reason about a third of the time, and find myself accidentally hitting hyperspace control often. Could we make a preference to disable or remap the hyperspace button?
Easy way to rack up a high score is to Not shoot clear all the asteroids, and instead do battle with flying saucers over and over. They're worth an order of magnitude more points especially the little guy who's good at not missing on his first shot.
