I will try to search some of the other Cube threads for information on registry editing and maybe get a bit more tips in a post. For now, those that know how to edit cube registry Music provided the points to look at.
For those (a bit like me) with little knowledge of registry editing, hopefully we'll see some kind of config application some point in the future.
And just to clarify, this is only currently tested to be working on an HTC Touch. If any FTouchFlo people on another device want to give it a try and let us know how it goes, that'd be great. But can't verify at the moment that the cube will function on any other device.
For more exact info on how a "4th Wall" works, check out Music's 4-sided cube thread
