⚠️ This mod is continuation of a rebranded fork (NormalASM) of L***ASM by Rongmario.
As of version 5+, this mod is now explicitly incompatible with VanillaFix and TexFix as their functionalities have been improved upon and added to the mod.
What this mod does:
Optimize RAM usage. Here's what happens when you add it to a large modpack (without Foamfix):
Fixes crashes, within different mods, and Forge itself.
Optimizes code in general.
As of 2.3, requires MixinBooter.
Recommend using VintageFix along with this.
