I made a TAS I think it looks "very lightning 4-2", I am wondering if it is. Also it looks to be rta viable if tweaked a bit (it also has some wiggle room(i think)).

practice rom used. (I wont be able to respond for the week this post is made because of a trip)

then you can see what R do you get and framerules i can check in a moment

okey is not you are 13 frames away from getting lightning you only lose 7 frames over perfect l+r tas in 1st room (this isnt l+r but just for comparition lol), but 26 frames in wrong warp room okey im not sure but the turn around seemed terrible lol in fact you can get there lightning with changing that by a normal strat with the wall turnaround

thanks this really helps. I wasn't really talking about wrong warp room (because there are "many" ways to do it), but the 1st room took me a while. the 1st room could totally be optimized after the elevator and before the elevator there is (prob) a strat for getting x132 faster (but with the same set-up) but idk, im just here to try to help with stuff. but thanks it really helped
