So: - just take the set of settings managed by winecfg (a subset of the whole registry, right?), - winecfg UI allows the user to specify that the current settings are specific to a certain app (identified by path name), - keep these settings in the registry (.../wine/winecfg/app1/...) - at launch time, the launcher checks whether the app has a specific set of winecfg settings, if so, changes the corresponding parts of the registry, and only then launches the app. [/list]
