Are there any editors or Software Development Kits for Hardwar?
Ouch produced a series of unofficial patches which altered prices. These were not developed for versions after U2.01. Editors for recent Hardwar versions have been produced by Solidox. Editors are available for items and hangars. Some can be downloaded here: http://www.downloads.hardwar.info/ . These do not work with U3 betas. Wez started developing a U3 beta hangar editor, which can be found here. REAxion has developed an editor for U2.04, HardLook.
