Can someone give me some splits for pokemon emerald or at least a general idea of what i should set my splits as?

You can set your splits to whatever you like, there's no required set up. Typically, for glitchless, runners have a split for each gym leader, the champion, and often for the 2nd Briney boat trip, just because the time between Roxanne and Wattson is quite long, and it splits them up nicely. However, feel free to have a split wherever you want, I personally utilize livesplit's subsplit plugin, and have many subsplits within each split, one for nearly every battle, just because I like having an accurate picture of where I lost/gained time.

We use in-game time for the glitchless category anyways, so your timer matters very little...

You have the flexibility to customize your splits of Pokemon Emerald Rouge as you see fit; there are no mandatory guidelines for their setup. Typically, in glitchless runs, participants choose to have splits for each gym leader, the champion, and sometimes for the second Briney boat trip. This arrangement is often preferred because the period between Roxanne and Wattson can be quite lengthy, and it provides a convenient way to break down the run. However, you are free to place your splits wherever suits your preferences. Personally, I make use of the Livesplit's Subsplit plugin, incorporating numerous subsplits within each main split. I do this mainly because I appreciate having a precise overview of where I either lost or gained time, which is especially helpful in tracking my performance during battles.
