Rare Golden Ship Galaga Glitch
https://www.youtube.com/watch?v=t_58poXHxOg&t=877s
The golden ship reemerges when the game switches back to the second player.
The enemy ship switched to the wrong characters for that sprite but kept the same color palette. If we assume that ship type is a single byte value, then that byte was somehow overwritten with a bad value, hypothetically a zero or a one which could be the value for the player ship. Errors like this could be caused by a memory overflow where a value was written outside the bounds of a table or the limited stack memory was exceeded.
I learned that if Player 1 exceeds 999,999 points, it will not display the millions in the score. It is not clear if the player's score still counts as being over a million, or if it goes back to zero. However, the second player does not have this problem and his score can reach 8 digits.
