That's really cool but I don't quite get it. How did they program a game within SMW? I mean, I listened to what he was saying, and I understood some of the words, but all in all it was WAY over my head.
How did you do this?If you really want to know then I suggest reading the submission text of the glitched SMW TAS, as the first around 100 seconds (until the game-breaking glitch) are the same.In short: I manipulate where the moving objects (sprites) are located or where they despawn, then I swap the item in Yoshi's mouth with a flying ?-block (thus the yellow glitched shell) and using a glitch (stunning) to spawn a sprite which isn't used by SMW and since it tries to jump to the sprite routine location, it indexes everything wrong and jumps to a place I manipulated earlier with the sprites (OAM) and because of the P-Switch it jumps to controller registers and from there the arbitrary code execution is started.Even shorter: Magic.
