For those who think Super Mario Bros. isn't difficult enough...
After two months and over 7,000 re-records, finally, the TAS for one of the hardest Super Mario Bros. 1 hacks ever has been finished, and I'm pleased to be publishing this to the userfiles of TASVideos! (Even though it's not much of a big deal here, I'm still pleased I finished this TAS.)
Super Hageo Bros. is an unbelievably hard Super Mario Bros. 1 ROM hack created by REI in 2001. This hack is one of the hardest ever, actually; in fact, savestates, slow-downs, and such emulator tools are strongly recommended to actually beat it.
My TAS takes no sweat against the hack and beats it to pieces. This is also about a minute and a half faster than Mars608's attempt.
