I've been running this around in beta testing for a few weeks now and I haven't heard of any crashes, so here for public consumption is 64th Note v0.09.
What's new: * Fixed uninitalized STATUS reg (PJ64 save state bug). This fixes the problem where playing certain track in order would freeze, for example Pilotwings after Perfect Dark.
* Cleaned up RSP setup/teardown.
* Fixed a minor, unimportant registry bug.
* Removed a lot of useless error messages and rephrased the important ones ("what's in code?" now actually tells you you're using an old USF, "seeking backwards not supported" is removed, etc.)
People who used to experience a lot of crashes report that v0.09 hasn't crashed at all.
