Not to my knowledge. PAL does have a 60hz option but I don't know too much about version differences.
a bit late... but no it is not slower to run on pal. pal50 is a bit harder to run on from what i've heard but it also has a slight advantage over ntsc and pal60 which is keeping blue eco after collecting a cell. saves like 2 seconds overall but i mean it's still something. but yeah in general the region doesn't matter, the version is the only important part. Since to do most of the runs a black label copy is required
After the recent Twitch changes to VOD storage that you've surely heard about, we've decided to no longer accept Twitch VODs for submissions to the Jak boards. From now on, only YouTube links will be accepted for video proof in a run submission, and we would encourage you to export any previous runs
