Game                     : 40-0  (Forty-Love Tennis game)
Manufacturer             : Taito
Game number              : A30
Vintage                  : 1984
Game serial/model number : M4300006B ?

I dont have the wiring harness for this board, so dont know if it works.
One GFX ROM is bad though.
See A30-26.u23\A30-26.txt for details about the bad ROM.

This is a four board system - Main, Video, ROM, and Sound boards.
