Hey, I am here to talk about various glitches and myths that go to retro video games like Galaga or Pac-Man. I'll start with Map 256 on Pac-Man. There are only 255 "normal" levels within Pac-Man. Once it gets to Level 256, it draws 256 fruit. That's obviously a problem, so the right side of the screen (which is where the fruit is aligned) turns into a complete mess.
Take a look:

Many people call it a kill screen. Why? The game checks for 244 Pac-Dots eaten by Pac-Man for the level to end. The right half of the screen contains only 9 dots. 122 on the left half plus the mere 9 on the right half is 131, not nearly enough to progress. (The nine dots can be consumed again on each life, but you can't get enough lives to make it to 244.)" Mrs. Pac-Man also has this bug, but it only has the screen go blank with nothing except Ms. Pac-Man and the ghosts.
Anyways, on to Galaga.

It has a Map 256 glitch too, but opon reaching that level, it adds an extra stage named stage 0. In a few seconds the game will crash and you have to reset it. Depending on the difficulty setting of the machine, this can cause the game to stall, requiring that the machine be reset or power-cycled in order to start a new game. Galaga can also have an exploitable bug that can cause the attackers to stop firing bullets at the player, due to a coding error. How to do this? If you do not kill two specific enemies and wait for 5 minutes, the ships will stop attacking you. Here's another: In the very beginning, you can shoot 2 ships at a time, and then with out killing anymore, let them kill you. You will get 200% out of 100% for firing 1 shot hitting 2 ships. Also occasionally, a ship may turn into something the shape of a barcode, possibly, but this has to do with a bug in the series. Another is where when the Yellow Minion is turning into a bonus ship, as its wings turn red, if you die the next time you come back up the wings will stay red until you kill the ship. (It works better in 2 player mode, because it's amusing to see it after someone else plays for a while.)
Hey, there's also an Easter Egg in Galaga. When the red ships are destroyed, they make a "wakka" noise. This is possibly a reference to Pac-Man. Also, in Galaga Remix, you are able to see "Star Bits" from the Nintendo game Super Mario Galaxy. That's all for now, I'll let you guys know if I find anything else!
