I am making a new and faster SMB all items TAS. Currently, I am 3 framerules ahead, 1 from MrWint's faster wall clip in 4-4, and 2 from precise optimization in 5-2 that allowed me to perform flagpole glitch while still avoiding fireworks.
Edit: Saved a framerule in 6-1 from a new strat and better optimization, so 4 framerules ahead now!
