Well, the rules don't seem to specify RTA. And FF9 states that segmented runs are fine. So It seems fine for the others, especially 7 and 8 to do segment runs.

Never assume segmented is allowed unless the category is for segmented runs. Most categories will use RTA or SDA timing that want the runner to be playing the game to completion from start to finish without saving and coming back to run it later.

FF9 having a segmented category doesn't mean it's okay to submit a segmented run to another game from that series when that game doesn't have that category.

Lastly, this is a question for that game(s) forums: https://www.speedrun.com/ff/forum

Why did you create a second thread for this when you already asked this question in another thread...

Either way, yes, this is a question for the game’s forums, not the main one. Although like KomradeKontroll said - if the game doesn’t have a segmented category, you can’t submit segmented runs.

Also, you seem to be twisting the rules of FF9. They don’t specify RTA because it’s an implied rule for almost every LB. FF9 has a single category for segmented runs. All FF9 runs are RTA unless they are the 2 runs in that category. But they are not saying segmented runs are fine across the board, they are saying they are fine for that one category.
