Just reporting that the leaderboard for this game submitted my score when I shot down a Boss Galaga that was attacking and had captured one of my ships. I lost one life before this happened if that helps. :)

Fixed up the leaderboard. Added demo protection and removed this cancel: 1=1S0xh0470=0S0xh0471=0

Not sure when it was added or it's intended purpose, but I think it has prevented anyone from submitting any leaderboard score since it was put in, as the leaderboard cancels any time you die.

The game goes on forever, so the leaderboard submits when you run out of lives (as it was already coded to do). Some extra juicy details: there's a BCD counter that loops after 999 to 0 this is the level display. And there's an 8-bit counter that after reaching 255 goes to 252, this is the true level and determines difficulty and patterns. This loop continues indefinitely.
