/*
    Atari Bartop 5200 prototype system

    Driver by Mariusz Wojcieszek
    Based on Atari 400/800 MESS Driver by Juergen Buchmueller

    Hardware was based on Atari 5200 game console with additional coin and timer hardware.
    System was intented to run in barrooms and taverns. Software was based on Atari 5200
    Realsports cartridges.

    Barroom Baseball is modified version of Realsports Baseball.

    Coins and timer were handled by Bartop system bios. Since bios dump is not available,
    regular Atari 5200 bios is used and game is marked as not working. Game cart is also
    marked as bad dump as it is done in "console style", i.e. one file for all game data.
