MpLua converter

This naive & hack-ish script converts a Lua precompiled-script from MpEngine VDM database to a version decompilable with luadec.

Usage

# Extract the target LUA compiled script from the VDM file
...
# Convert it
$ python3 parse.py extracted/out.1.luac /tmp/export.luac
# Decompile it
$ luadec/luadec /tmp/export.luac
