Hi, my name is Andrea <Neogene> Leganza.
I managed in about some hours to modify wiidesktopvr to compile and run in a 64bit env (Vista in my case).
http://www.leganza.it/dblog/articolo.asp?articolo=47 here there is the solution and here
http://www.leganza.it/WiiDesktopVR_x64.zip you can get a full versione working for me (with wiimotelib 1.2.1 lib)
Problems for me were:
- current version of widesktopvr gave me BADIMAGEFORMAT (resolved using x86 compiler command)
- application doesn't find the wiimote (resolved changing to 1.2.1 lib, removing old dependece(networkserver.cs) some calls changed from version 1.1 to 1.2.1: GetBatteryLevel() not found -> replace with getStatus() (for remote2 and remote instances) ; OnWiimoteChanged -> replace with WiimoteChanged (for remote2 and remote instances)
I hove it will help all the x64 boys.
