You'd need to ask in the Hollow Knight community itself, whether on the SRC Forums on the game's page or Discord. They already have ILs for some trials and pantheons with any bindings and all bindings as a drop down toggle.
Gotta check the rules for the specific game on the game page or ask within that community. Typically for MP runs only one person has to record and it's usually the host, but it can vary hence why you'd have to go through them to find out.
I mean you can literally have a timer going on your phone so you can see your "final time" if that's what you're concerned about... They do also make timer apps for mobile which people do use.
If you're talking about doing LBLJ, part of the thing thats gonna save you time in the route is doing those specific stars since they are faster. If you're not confident in stuff like that to start, just do the No LBLJ route. https://ukikipedia.net/wiki/RTA_Guide/16_Star
Short answer: no. Have to get the official WAD for anything attempted on VC. Always check the rules, my friend.
Emulators are not banned by Speedrun.com, prime example being Super Mario 64. Thing is a question like this needs to be asked to the community directly because the communities are the ones that decide about emulator usage. That being said, this is a Flash game so there's not really going to be an "emulated version", but you really should be talking with the Papa's community about these questions you have.
Best to look at the resources for the game since that's where they'll put things like autosplitter and load remover tools and if you're still unsure about something, you need to talk with that community in particular whether you do it on the game's forums or in the community's discord.
You need to talk to them about anything Co-op, not here. This is vanilla.
The hack has its own boards.
You need a bad rom in order for that to even happen in the first place and the guide does list the checksums you can verify with. Even if thats the case, Rosalie's Mupen is the alternative if you don't wanna be super paranoid about it.
Simply put, no, not if you want to get a run verified on the leaderboards. There are 3 emus listed in the rules. If PJ64 1.6 isn't working for you for whatever reason even after double checking the pj64 setup guide, try Rosalie's mupen. You can also join the discord for actual help with setting stuff up if need be.
https://www.speedrun.com/d2lod?h=Co-Op-normal-8-man&x=zd3qgvnk-0nwpjqd8.5lm00dy1-6nj5d1el.zqo6k05q just need to look at whatever boards to see whats available.
Duplicated you added in 1 extra star because you forgot to account BoB star.... I beg of you, Poggers, to go to the mario speedrun discord and ask questions there because you'll get better advice. That being said, if you don't have the Usamune Practice ROM, you should get that to actually practice the CCM stars more effectively. They're really not bad.
