Game's rom.

MAME Info:

0.57 [Aaron Giles]


- 0.122u7: Zsolt Vasvari fixed invalid memory_install_*_handler calls in drivers\williams.c. Emulated external OR circuit for all drivers using the PIA chip. This used to be internal to the PIA emulation, but, in fact, this is external logic. The PIA has two seperate INTA and INTB out lines. This fixes at least PlayBall.

- 0.95u3: Changed cpu1 roms addresses from $0-8000 to $10000-18000.

- 0.57: Aaron Giles added PlayBall! (prototype) (Williams 1983).

- 4th December 2001: Aaron Giles added PlayBall! to the Williams driver and fixed some sound problems in it.
