📋 About This Mod
A LaunchWrapper/ModLauncher CoreMod to prevent players from launching the game via a crappy launcher.
"Crappy Launcher" refers to a launcher that may cause performance and even compatibility problems that are extremely difficult to diagnose through debugging and other means, such as by messing with the game files and quietly adding JVM parameters for so called "optimization reasons".
Such a crappy launcher may also be a potential computer virus hazard, for example, calls system-level high risk libraries such as kernel32 for suspicious activities.
This mod plans to detect the crappy launchers exclusive to each OS by various methods, and throw exceptions when players try to launch the game using them.
To a certain extent, it could take care the confusion for modpack authors who need to solve potential problems that may be caused by launchers.
Only support Forge, no plans of Fabric port.
Use retro version for <= ``1. 12. 2``, modern version for >= ``1. 13``.
