if i remember right the previus version of amigaforever that i have, has alread some parts of os3.9 include with it and licenced too. personaly i don't like it because it's not a full 3.9 package with uae too. i don't know if in versio 2005 has been improved or not. i wouldn't buy 3.9 just for uae though... it's double cost
