I've looked into all of these before, but was not able to find any freely-redistributable unpackers for them. If you know of any, please suggest here, otherwise this will need to stay on the unsupported list. here is free unpacker for PeCompact with source code, also some other unpackers with source http://cdw.cd.ohost.de/programme.htm http://cdw.cd.ohost.de/Un2Pec.zip it's say is tested on version 2.55/2.64/78/79, but work even on 3.03
