hello, i am quite new to speedruning (i just created a speedrun.com account today), can someone explain what all the stuff on the submitting page for inbounds no SLA means?

im scared im gonna get my run rejected or something

thanks

unless you cheated it won't get rejected, verifiers will correct whatever is off.
the subcategories are unrestricted and legacy; most runs will fall into legacy, unless you do 00 vaultskip, 17 vertical angle glitch, and/or e01 angle glitch saveglitch (you can read more on these on the ultimate speedrunning guide in the guides section if you don't know what these are).
the "segments" option is for some reason still a thing even though it's basically obsolete, depends on if you loaded any save. if you did not load any save (including vault save), the run is ss (single segment). if you loaded any save, quick, auto, vault, etc., the run is rta.

Other things to note for more general (non-No SLA specific) stuff:
Timing
Time without loads:
If you submit with video(or video + demos)-> You would put your time from livesplit using the autosplitter and game time setting.

If you submit with demos only -> You would put your time calculated using one of the demo timers here.

(further explained in the submission and setup guides which can be found in guides.)

Time with loads:
If you are submitting a video only AND you are not using the autosplitter then you would put your time here. (It is strongly recommended you use the autosplitter as your time will be placed below all runs that use "time without loads" otherwise).

Segments -> Explained by alias above
PC/Console -> Self explanatory
No SLA/Segments -> Explained by alias above
Platform -> Self explanatory (emulators should not be ticked on)
Date -> Date which you did the run on
Video Link -> Self explanatory (Do not put demo links here)
splits i/o -> Optional, basically lets you link more info about the run
Description -> You can put anything here. Also, if you are submitting a run with demos (either demo only or video + demos) this is where you would put a link to them.

thanks, i understand now
