I have not yet looked at the Decoda code to closely but there are a
couple of methods, you can inject a patched dll/so/dylib, do the work
of the linker yourself fixing up function addresses or if Lua is
statically linked you can patch the executable using trampolines. All
of which are architecture/platform specific (unless using Microsoft's
Detours, which is free for open source usage) hence why I assume
Decoda is only currently able to target Windows x86.
