Great discovery, EvilJoven! I just relied on the DirectInput-documentation from Microsoft and that never ever hinted at what you've found out...
Reverse Engineering scores a point over RTFM!
Now the question is: Is TD prepared to rely on an undocumented feature (mixing DirectInput with Win32 API) in order to solve
a serious inconvenience for all those having more that 4 controllers...
I surely hope so! TD, please?

Edit, PS: You're sure that it is "HKEY_CURRENT_USER\System\..."? I find all you've written about under "HKEY_LOCAL_MACHINE\System\..."
