Decompiled 3.2b2 against Forge 184.108.40.206 and IC2 1.70b, fixed API changes. Seems to work. I did not change anything about the source itself [ Short of moving the GUI classes into the main advancedmachines package ]
I'm also not including that source in the download ... it's not needed for a port to Bukkit. Which i dont want to do. Its late.
Updated to use ModsLoaded() instead of load(), should fix the empty recipe Rotary Macerators once and for all. Also, split off just the Machines. In any case, that rewrite is probably your best bet.
