Just to add some context, arbitrary code execution in Super Mario World is nothing new, it has been known since 2014. There was a tool assisted demonstration at Awesome Games Done Quick 2014 [1] where they inject a pong and a snake game using a TASBot (a robot controller that replays input scripts to the console). And in 2016 a streamer performed it manually to inject a flappy birds game [2] (this second video is really good, he goes into detail of the process). So, what this newer demonstration brings is the use of the known arbitrary code execution capabilities of "Super Mario World" to help finish all 5 games in "Super Mario All-Stars + Super Mario World" as quick as possible.
