I'm an academic working on a book about the relationship between the design, play, and political philosophy of videogames. One of the chapters is a semi-historical account of practices related to tool-assisted speedrunning, and I'd like to get my facts straight. I'm working on a section on arbitrary code execution right now, and I'd like to identify a rough origin of the practice; from what I can tell, Masterjun popularized it with the credits warp for SMW (
http://tasvideos.org/1945M.html), though it sounds like he didn't originally discover it - or at least that it involved あんた (anta) and p4plus2. And I'm not at all sure about the existence of other forms of ACE that predated the SMW credits warp. If you can point me to any other, earlier instances of ACE in TASVideos or elsewhere, I'd be very grateful.
Thanks!
