I just checked Miniland's 5:05 WR and 1-1 is completed on 30.xx? Does this have to do with waiting with the floor clip or PAL smb1 itself? Also, I was messing around in 1-2, jumped off the second platform at the end and floor clipped. You can clip through the 'entities' of platforms! I believe that you must jump on the first frame though. Could this save time?

just pal being slower. the reason you floor clip is for ffpg and that saves time over just running to the end. there is a way to do ffpg without floor clip but it is very complicated. and in 1-2 this does save time similar to 1-2g. happylee has a pal tas you can watch here and a comparison between ntsc and pal tasses.

thx. I was intending that maybe this could be done in a run?

im sure the 1-2 floor clip could be done in a run but im not sure it is sub-pixel dependent or how the exact mechanics of it work. you could ask Miniland. hes one of the only top runners who plays on pal to my knowledge.
