I understand the situation, but unfortunately that's a personal limitation rather than an issue with the rules. The break rules were voted on by the community and apply equally to everyone. We already allow breaks during longer runs, which is more flexible than many speedrunning communities, but we can't make exceptions based on individual schedules or screen time limits. Otherwise, we'd have to account for all kinds of different personal circumstances, and the rules would quickly become difficult to apply fairly. If a category isn't possible within your current screen time limits, then it may just not be feasible to run under those circumstances.

darker's cool and so is this wr

I have both a PAL and a USA rom, and I was wondering what version differences are there and which is faster. I know there's a challenge in Battle Arena that has a time limit of 60s in U but 75s in E.

Is it allowed? I know gameplay-enhancing cheats like speed modifiers and stuff are banned but does this apply here?

With normal course order, one can use livesplit for this category.
