The roll animation is one frame shorter on PAL than on NTSC which has a surprisingly huge impact on some glitches.
- you can't megaflip/megasidehop/HESS off of single frame damage sources as in:
> Deku Baba megasidehop as B1 skip (you can still do something
like this)
> GS WESS for Mido skip
> GS WESS in Zora's River for the rock clip
- that also cancels ISG in midair or before Link leaves the ground:
> 37th HP in Gerudo Fortress as child using a megaflip to reach the loading zone (hovering over the wall inside the building still works)
> Tektite hover for fishing pond early
> Gerudo bridge megaflip using ISG near the ledge
> forest escape using the Business Scrub (Cosmo escape)
> faster Deku B1 skip method of the GS hover with a megaflip
- some timing based tricks involving rolls become more difficult or might not work at all:
> rolling from the switch in Jabu Jabu's Belly
Maybe some of these glitches actually work but their positioning would be incredibly precise. One bomb superslides are possible on PAL as an example but noone has found a consistent way of performing them as adult.
