The following types of threads would go here:
* Announcements of a 3rd-party build of StepMania (and the ensuing bug report thread)
* Ideas directly concerning a 3rd-party build.
* Songpacks that are DEPENDANT on a 3rd-party build.
As of this time, I am aware of two completely unofficial builds: SM3.9+ and the 4-player SM build. (the recently released but still unofficial 4.0CVS SMO build, I believe, is mostly based on the current code, and as such, I did NOT move it here)
STANDALONE MIXES THAT USE UNOFFICIAL BUILDS DO NOT NESSESARILY HAVE TO BE HERE (although that would help us keep track of them).
