Given that most of us are not very patient, and seek out the latest "work-in-progress" builds anyway from sources such as:http://www.emucr.com/2012/09/supermodel-svn-r270.html
...perhaps Bart might consider creating a Beta sub-section to the Supermodel 3 - download page:http://www.supermodel3.com/Download.html
The latest "Beta" or even "Alpha" build could be posted there with a clear disclaimer..."Use at your own risk, Alpha build, unstable...etc, etc".
Then when the "Beta" build get promoted to the stable build it gets moved up and a new Beta build it put in place for the "non-stable/testing" area.
At least that way all us fans can go to the Supermodel 3 website rather than other places looking for the latest build but it's still understood that a stable build it not available yet.
The .2a version would still be posted as the last official build. Does that make sense?
Just a friendly suggestion. As always, thanks so much for the wonderful time and skill put into this fantastic emulator!! Thanks Bart (and team)!!
