According to the mod page: http://www.moddb.com/mods/kanes-wrath-mod-sdk, four updated download links are there (including WrathEd), but there has been no mention on what the new changes are. So if there are some new implementations, I would like to hear them.
For the WrathEd 1.05 tool, download here: http://www.moddb.com/mods/kanes-wrat...s/wrathed-1052
For the updated KW mod launcher, download here: http://www.moddb.com/mods/kanes-wrat...d-launcher-104
Edit: It appears that custom sounds for new units as well as the custom menu image and changing the APT mod string defines are now working. However IDK why sound asset files are needed to be compiled and used when wav sounds are already present. Not sure about the "inherit" define yet.
