Summary	08731: bsharkjjs: Left/Right inputs are reversed except when "Mirror screen" dip switch is on
Description	Pushing left goes right and right goes left, but if you set the machine to mirror the display with the dip switch "Mirror Screen" the controls function normally. They function normally in the service menus both ways though, weird.
Steps To Reproduce	1. Run bsharkjjs 2. Start a game, and try pressing left and right. Controls are reversed. 3. Now TAB to the DIP Switches and turn on "Mirror screen" and exit. 4. Run bsharkjjs with -flipx to correct the screen orientation for the next step (this just makes things easier). 5. Start another game and press left and right, they work correctly now.

They work fine in mame because have the Input Setting -> Analog Input Adjustement -> AD Stick X Reverse set to ON. I think also in this bsharkjjs left and right are inverted by design in the arcade machine. So, I think correct solution is to invert Left and Right Input in IN2 PORT Definition.
