1: for co-oop runs is aternos allowed, if not what are some free hosts that can be used

2: for fabric loader what do i need to show/ do i need to show the mod folder or anything like that before starting the run?

3: can i use the SpeedRunIGT mod's recording for the runs? if yes is there any specific settings?

1. I'm quite certain that aternos is allowed.

2. Short answer: No Long answer: If it's a sub 17 run, you gotta show it when SUBMITTING

3. Uhh... I think SpeedrunIGT doesn't have video recording, it only has time recording as RedLime himself stated "wdym, speedrunigt doesn't record any video"

Yeah that's it.

Don’t use aternos it’s bad and idk how you would easily reset. Use ngrok and the force port mod. Here is a tutorial setting up the server:

N00bie if it is sub 17 what should I show when submitting

The rule says it all but... here you go:

sub-17 runs must submit world files and evidence of past attempts (just for 1.16+ any% glitchless bcuz I assume you run that category, if you wanna see for other categories, CHECK THE RULES, I REPEAT, CHECK THE RULES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!)

genuine apologies, i cant find the rules anywhere so ummm if its not sub 17 i dont have to submit like world files or mod folders right?

Yes in 1.16+ nothing except vid is needed
