Comment 1 for bug 581711

With additional time to look at this issue, the last mentioned 'fix' was a workaround. The required fix is to add 'keyboard': u'Keyboard', into the controllers array starting at line 74, ie

this,

_controllers = {
    'joy2way': u'2-Way Joystick',
    'vjoy2way': u'Vertical 2-Way Joystick',
    'joy4way': u'4-Way Joystick',
    'joy8way': u'8-Way Joystick',
    'stick': u'Analogue Joystick (or ~270\xb0 Wheel)',
    'doublejoy2way': u'Double 2-Way Joysticks',
    'vdoublejoy2way': u'Double Vertical 2-Way Joysticks',
    'doublejoy4way': u'Double 4-Way Joysticks',
    'doublejoy8way': u'Double 8-Way Joysticks',
    'lightgun': u'Light-Gun',
    'paddle': u'Paddle (or ~270\xb0 Wheel)',
    'dial': u'Spinner (or 360\xb0 Wheel)',
    'trackball': u'Trackball',
    'pedal': u'Pedal',
    '': u'None'}

becomes,

_controllers = {
    'joy2way': u'2-Way Joystick',
    'vjoy2way': u'Vertical 2-Way Joystick',
    'joy4way': u'4-Way Joystick',
    'joy8way': u'8-Way Joystick',
    'stick': u'Analogue Joystick (or ~270\xb0 Wheel)',
    'doublejoy2way': u'Double 2-Way Joysticks',
    'vdoublejoy2way': u'Double Vertical 2-Way Joysticks',
    'doublejoy4way': u'Double 4-Way Joysticks',
    'doublejoy8way': u'Double 8-Way Joysticks',
    'lightgun': u'Light-Gun',
    'paddle': u'Paddle (or ~270\xb0 Wheel)',
    'dial': u'Spinner (or 360\xb0 Wheel)',
    'trackball': u'Trackball',
    'pedal': u'Pedal',
    'keyboard': u'Keyboard',
    '': u'None'}

The gamelist will build completely using listxml as list_generation_method on mame137 and above builds
