For the record, there are currently no new ENTIRE sound fonts available (8-17-2011)... only sound "extras" / packages.
These sound packages can replace one or many sounds (for example you can use a "darkside poweron" instead of the default poweron)... but you *MUST* have a sound file in every other folder for the Obsidian launcher to function properly.
In other words--you
must have:
* A boot sound
* A poweron sound (only ONE)
* A poweroff sound (only ONE)
* A lockup sound (only ONE)
* A motion sound or sounds (1-12, no more, no less)
* An impact sound or sounds (1-12, no more, no less)
Again, you *MUST* have all these present, or the Launcher will not allow you to proceed.
When the "actual" new fonts come out... never fear: they will be "complete" fonts, and NOT simply be "extras" packages. However... some fonts will ADDITIONALLY have their own extras packages as well!
Keep that in mind.
