Line 12:
#Download a MMC/Prism Java9-19 version of the pack from http://downloads.gtnewhorizons.com/Multi_mc_downloads/ (it might just be labelled Java9, that is still correct; currently (12. Mar 23) the Version labelled "...(MultiMC)..." is the java 8 Version, the version labelled "...(PrismLauncher)..." is the java 17-19 version. Drag it into the MultiMC/Prism window to create the instance.
#Under settings - Java, make sure you are using a new version of Java, best 64-bit Java 17 or 64-bit Java 19. In the case of Java 17 make sure you are updated to at least 17.0.6, older variants can cause start-up errors. Java 17 can be downloaded [https://adoptium.net/temurin/ from Adaptium].
#If you are using MultiMC you also need to add the additional Java arguments from [https://github.com/GTNewHorizons/lwjgl3ify#client here]. You only want the Java args from that page, nothing else. This step is not needed in Prism.
If you are experiencing issues with fullscreen mode, set a resolution in your launcher and check other settings in the config/lwjgl3ify.cfg config file.
