Have you tried applying any of this to (segments of) 68k binaries?

You mentioned that a decompiler would have been only slightly useful for older games written in C/C++; is flow analysis not helpful in practice for simplifying code that was originally hand-coded in assembly?

Edit1: Thanks for the link to the paper[1], by the way. Do you know of any other good resources?

Edit2: Nevermind, I see you have them in github[2]. Thanks again.
