I get that people are complaining about bugs, but its still quite an achievement to decompile to commented source with meaningful function names and variables, and just be able to recompile.
It turns out this is not what author claims to have done. Recreation from scratch is the claim. https://github.com/storytold/photocraft
Age of decompiling to reasonably named functions is here though. https://github.com/morluto/rea . Which is what I assumed was used to clone.
