Update to 0.35r4:

    * Joystick buttons for x and y axis control can be reassigned,
    too. This is especially useful if you want to use digital
    buttons instead of an analog controller. Thanks to Jon Chalos.
    * Fall back to non-accelerated YUV overlay, if no hardware-accelerated
    is available. This is much slower but a modern machine should
    be fast enough and it's better than having no fullscreen mode
    at all.
    * The command-line parameter '-c' wasn't handled properly, so
    it didn't work at all.
    * Don't link against X11 libraries if compiling the SDL
    user-interface.

    * Applied fix by Barry for the ABCD instruction. This fixes,
    for example, the odd characters in the score count of Streets
    of Rage as reported by bootsector.
    * Fixed soft reset so that the RAM is not cleared in this case.
    Thanks to Fibonacci for reporting this.
    * Reduced noisy blips that may happen whenever an underrun of
    the audio buffer occurs.
    * Fixed crash that would happen if the filename of the ROM did
    not contain a dot.
    * Fixed endian issue with big endian platforms introduced by
    previous changes.
    * Added simplistic support for reassigning joypad/joystick
    buttons. Look for joy[12]_{a,b,c,start,left,right,up,down} in
    ~/.genrc.
