#Fadec is an opcode decoder.
Fadec takes in x86 or x86-64 machine code and decodes it into assembly. Decoding instructions is very simple, and is performed by indexing a very fast and reasonably sized (24 kiB) lookup table. Fadec can also encode (#Faenc) machine code by building instructions from macros.
