Super Mario World arbitrary code%

How it works is by arranging sprites in the overworld in a specific way, then stunning a flying ? block to generate an object with sprite FA, which due to a well-known glitch in the game jumps to object memory. The overworld sprites are arranged in such a way as to pass program flow to the controller inputs, which are then used to, in this case, inject Pong and Snake into SMW (another arbitrary code% TAS uses it to jump to end of game).
