Sprite Lag

Sprite Lag is a hardware issue that playthroughs of Link's Awakening often run into. The original Game Boy was designed to operate smoothly with a maximum of eight sprites on screen; any more and the frame rate begins to drop precipitously, threatening the gameplay experience. Unfortunately, this was such an ambitious game that the developers often crammed the screen with sprites, leading to significant sprite lag.

Of course, there is also often lag when fewer than eight sprites are on screen. This is because the code in Link's Awakening is insanely janky.

Sprite Lag is one of the things most commonly edited out in Glitch Runs.
