@EngineerRunnerEngineerRunner I guess you could (though i don't see why you would), but it still must follow the resource pack rules laid out here: http://bombch.us/DOOK

@2001WindowxpOfficial2001WindowxpOfficial According to some people in the Javacord, the achievement 'Adventuring Time' is impossible in 1.7 due to a required biome being in the End, yet it is unobtainable when entering, therefore making All Achievements in 1.7 impossible.

There's also a tool called ModCheck which can make it so you have all the legal up-to-date mods. https://github.com/RedLime/ModCheck

Make sure you are using java 16+, there are instructions in the discord, just go to #bot-commands and type !!wp and you'll get the instructions.

I assume you're using livesplit, instead I recommend using SpeedrunIGT (in the resources page on this website) as it is a direct mod and allows for more control over the timer and it's settings/rules.

MultiMC and the vanilla Minecraft Launcher are the only allowed launchers.

Specnr's macro is the one people use for The Wall, which is what you mentioned Crookst as doing. This is the setup video for it:

There is a mod available in the discord, just go to the bot channel and type !!borderless, this mod is legal for use in speedruns. Other than this mod, I don't believe there is any other way to get Minecraft into Borderless mode.
