Yes, all of it. Including the bouncing polygons, of course. And since it's
placed at the end of ZUN's code inside the executable, the code's already
position-independent and fully hackable.
This executable is embedded into all 4 versions of ZUN.COM. It was written by
KAJA, not ZUN, so we don't care about anything in there - not that it would
matter for porting anyway. We only need that binary to be able to create
bit-perfect rebuilds of ZUN.COM in the future.
