It’s quite tedious tracking all the register effects, though good signatures annotated with in- and out-registers helps a lot. I feel like a compiler, manually performing control flow structuring like the Relooper or LLVM Stackifier algorithms. With this completed, my manual effort will bootstrap reverse engineering the rest with a proper decompiler. Thalia
