Line 9:
The technique in its simplest form can be used to modify the sprite dimensions and data representing the sprite, in order to modify how glitches relying on glitch sprites affect data such as the Hall of Fame (see [[Hall of Fame corruption]]).
The most powerful form of the glitch involves [[arbitrary code execution]] or otherwise a modified save file. By encoding their own compressed sprite (which is made easier using tools), the player can insert a custom sprite into the game within other technical constraints (such as one palette with limited colors).
While technically, arbitrary VRAM or SRAM sprites are possible, these regions may be locked making the glitch harder to exploit, especially for VRAM in which the quirks of [[VRAM inaccessibility]] apply.
