Here's a thing I done made that re-assembles LuaJIT from it's assembly-bytecode (or when used with LuaJIT itself can decompile LuaJIT files)
This version is good enough for me (at the moment) so I don't think I will be updating it any time soon
Things that still need to be added:
- table lookups
- uget lookups (if thats possible?)
By using this you agree that you will not modify anything for malicious purposes, or redistribute source code (decompiled or not) of anything using LuaJIT
