In FT Improver I've made use of several Windows API functions which in MS Windows SDK 2008 are documented as functions which require Windows XP SP 2. However I analyzed old MS Windows SDK and found that these functions are also available in Windows 95 and 98. The difference in requirements refers to some new parameters which were introduced since Windows XP SP 2. FT Improver does not make use of these new parameters thus it should also work on Windows 95 and 98. Windows SDKs are also backward compatible. I don't have Windows 98 so I can't check it. LinuxLiesLove & Ardanis, I will consider your suggestions. LinuxLiesLove your suggestions are quite complex and hard to implement and require a lot of knowledge, however they may be implemented in future. What do you all think about patch that adds dialog interface similar to that from classic Fallout, dialog options would be added dynamically by using game triggers? Is it for you an important game feature? I ask because I have this patch in my plans.
