Changes :

Many improvements to input handling, particularly with the mouse and paddles:
The mouse can now be used to emulate a joystick, booster-grip or driving controller.
The mouse now controls only one device at a time (1 of 4 paddles, 1 of 2 joysticks, etc), instead of devices from both virtual ports.
The sensitivity for digital and mouse input (for paddles) can now be set separately with the 'dsense' and 'msense' commandline arguments, and from within the Input Settings UI.
Added support for the 2600-daptor device (http://2600-daptor.com), which is similar to a Stelladaptor but improves handling of paddles. Thanks go to Tom Hafner for a complimentary test sample of this device.
Added new controller types 'Paddles_IAxis', 'Paddles_IDir', and 'Paddles_IAxDr', which invert the paddle axis, direction, and axis+direction, respectively. These are used for certain ROMs that have the axis or direction inverted from normal (for example, using the paddles causes on onscreen object to move up and down vs. left and right). All applicable ROMs in the internal database have been updated.
Added preliminary support for emulating ARM code to the DPC+ bankswitching scheme (thanks to Batari). Related to this, fatal errors in the DPC+ ARM code are now caught and shown in the debugger.
Updated internal ROM properties database to ROM-Hunter version 6 (thanks go to RomHunter for his tireless research in this area).
The ROM audit dialog now automatically selects the current directory in the ROM launcher, and reloads the directory after the audit is complete.
Removed the 'grabmouse' functionality; the mouse is now always grabbed while playing a game, and released otherwise.
Updated built-in version of the PNG library to the latest version.
