unprofessionally:

I’ve grown into a habit of staying to watch the credits and stay in theaters until the very end—when the projector is turned off. I was happy I stayed until the bitter end of Wreck It Ralph, and discovered a half-glitched Disney logo in the final seconds of the reel. I recognized it as the split-screen glitch from Pacman, a very genuine homage to the games the movie was modeled after.

Here’s some background on the glitch for those that don’t know, courtesy of Wikipedia:

Pac-Man was designed to have no ending – as long as the player keeps at least one life, he or she should be able to play the game indefinitely. However, a bug keeps this from happening: Normally, no more than seven fruit are displayed at the bottom of the screen at any given time. But when the internal level counter, which is stored in a single byte (8 bits), reaches 255, the subroutine that draws the fruit erroneously “rolls over” this number to zero, causing it to try to draw 256 fruit instead of the usual seven. This corrupts the bottom of the screen and the entire right half of the maze with seemingly random symbols, making it impossible to eat enough dots to beat the level. Because this effectively ends the game, this “split-screen” level is often referred to as the “kill screen”. Emulators and code analysis have revealed what would happen should this 255th level be cleared: The fruit and intermissions would restart at level 1 conditions, but the enemies would retain their higher speed and invulnerability to power pellets from the higher stages.

A very nice touch.
