Description
IMPORTANT:
FermiumASM is a fork of NormalASM by skmedix licensed LGPLv2.1;
Which is an updated fork of NormalASM by mirrorcult licensed LGPLv2.1;
Which is a fork for rebranding to remove "questionable" content of L**iASM/CensoredASM by Rongmario licensed LGPLv2.1.
As with the original and the forks, FermiumASM makes multiple improvements, optimizations, and bug fixes to Minecraft, including but not limited to:
- Optimizing RAM usage, especially in larger packs.
- Fixing multiple crashes, in Minecraft, Forge, and some other mods.
- Multiple performance improvements.
- Crash handling to allow you directly upload crash reports to mclo.gs.
While the NormalASM forks only rebranded and stayed updated with CensoredASM, FermiumASM on the other hand does more significant changes to its function:
- Refactored and modified to use and depend on FermiumBooter, an alternative to mixin loading, replacing its dependency on MixinBooter.
- Removes internal Spark profiling as it is both incompatible with, and superseded by, the updated fork Spark Unforged, allowing for better profiling.
- Removes the chance to pick a random author to blame in a crash report.
- Rebranded user-facing and logging branding, including icon and url, to FermiumASM, and updated authors to recognize fork authors.
As with the original, FermiumASM is incompatible with VanillaFix and TexFix as their functionalities have been improved and added directly to the mod.
FermiumASM does not depend on MixinBooter, it now depends on FermiumBooter.
FermiumASM has been tested as working within an active modpack and should perform accurately as a replacement to the forks or original mod.
Due to the changes, if you have any issues, please report them to the linked issue tracker at the top for FermiumASM, not the original mod.
