Stella SVN r2230 is released. Stella is a multi-platform Atari 2600 VCS emulator. The Atari 2600 Video Computer System (VCS), introduced in 1977, was the most popular home video game system of the early 1980's. Now you can enjoy all of your favorite Atari 2600 games on your PC thanks to Stella!

Stella SVN changelog:
r2228
Huge improvements to paddle and mouse handling:
- mouse can now emulate joystick, booster-grip and driving controllers
- digital and mouse sensitivity for paddles can now be tweaked
separately, and have a greater range
- the mouse now correctly honours its controller setting, and only
controls a device on one one port (not both at the same time)

Added support for 2600-daptor device. Credit for creator of device
is forthcoming. This device is basically an updated Stelladaptor,
with improved handling for paddle data.

Grabmouse functionality is no longer user-definable; the mouse is
always grabbed while playing a game, and released otherwise.
r2229
It seems that the NIB format for the OSX project files has changed.
r2230
Added controller types 'Paddles_IAxis', 'Paddles_IDir' and 'Paddles_IAxDr',
which are specialized paddles classes that invert the axis, direction,
and axis+direction, respectively. Updated all applicable ROMs in the
properties database.

Cleaned up the menus in the OSX port; some of them weren't even tied
to anything. I'm seriously considering removing them all, except for
the Help and Quit items.
