Currently, this repo uses a fork of Unicorn made by @geohot https://github.com/geohot/unicorn.git
George said he made a few fixes to it, which do have to upstream and/or merged upstream before we can switch over, so we should track, push for the fixes to be merged and switch when we can.
Quick search releaved the following issue: https://github.com/unicorn-engine/unicorn/issues/1470 but that seem to be fixed, but there seems to be more than that here: https://github.com/geohot/unicorn/commits/master
@geohot Could you comment as to what we need?
