Hi guyz, I'm the author of this project, but not the author of this post. Indeed the project is very incomplete and indeed it's "disassembler" - not "decompiler" :)
I plan to talk about it on HN when I'm satisfied with the results (and when the emulator starts outputting things)... today was a little early.
Thanks though for the upvotes and the kind remarks!
Cheers and happy 2017!
