/*

    Laser Battle / Lazarian (c) 1981 Zaccaria
    Cat and Mouse           (c) 1982 Zaccaria

    driver by Pierpaolo Prazzoli

    The 2 games have a similar video hardware, but sound hardware is very different
    and they don't use the collision detection provided by the s2636 chips.

TODO:
- how to use the 82S100 PLA dump
- colors (tile_index in tilemap needs to be adjusted)
- sound in laserbat (with schematics) and in catnmous
- cocktail support
