I was working on warpless TAS and after making 4-4, I realized that it this combination is better then any perfect combination for warps TAS or other levels from my warpless TAS. It is not too hard to save this framerule (my TAS is still 1 framerule behind WR), but I did really intresting optimization and I ended up only 9 frames behind framerule with using different strategy for clip and firebar! The WR using screen position manipulation to go through firebar as quick as possible, but my previous TAS didn't use it and was still very much slower then my new, so I left it and it is enough for me for this step. It even adds some different type of challenge. Very much things goes on here, fast acceleration can't be too fast, because Mario would fall down, then perfect clip, going down, acceleration back, avoiding firebar and barely winning bowser fight, which is very challenging on this level too. Anyway, I could miss more intresting level, because I didn't use some tricks and timesaves in my current TAS. What is your favourite level for TASing SMB? Or what is your favourite level from TAS world record in 18:36.78 (TAS timing) by HappyLee&Mars608?
