Summary	08597: a5200: Start game button doesn't start game
Description	Starting with MAME 0.253, I noticed that several Atari 5200 games can no longer be started with the start button (keyboard "1" or joystick button 1). I confirmed that MAME 0.252 works fine and doesn't have this issue.
Steps To Reproduce	1) Run an Atari 5200 game such as Pitfall 2 using MAME 0.253. Example: "mame a5200 pitfall2". 2) After Atari logo, press keyboard button "1" or joystick button 1 to start game. 3) Game does not start as expected.
Additional Information	As mentioned, Pitfall 2 runs fine doing the same steps listed above with MAME 0.252. This problem was first noticed in MAME 0.253.
