Well I have been working on getting the WiiWhorld visuals working on my XP x64 64-Bit System.  The only working 64-bit virtual midi driver I can find is Loobe1 (http://www.nerds.de/en/download.html).  This has build in feedback protection which gets overloaded by excessive dumps to the midi channel.

The WiiWhorld script needs some heavy coding to get it to be compatible with the LoopBe1 feedback protection.  It shouldn't take me more than a day of work.  It is a matter of reducing the granularity, timing, and reseting of the bus.

Updates to follow.
