    In the weekend i was bored, so i wrote a little and quite easy unpackme. Anyway i think it will be a good challenge for newbies and some intermediate reversers. Goal is to have a clean unpacked file, file should work flawless and without exceptions. The unpackme is tested on Windows XP and higher, and will not work on win2k (you'll discover why by yourself). Difficulty: 2-3/10 (my personale opinion) Good luck. Pass: unpackme2009 UnpackME_2009.rar
