United Amusement PC-Engine based hardware
Driver by Mariusz Wojcieszek
Thanks for Charles MacDonald for hardware docs
Overview
The system consists of a stock PC-Engine console, JAMMA interface board,
and several cables to connect certain pins from the PCE backplane connector
and pad connector to the interface board.
History
In 1989 United Amusement (a large operator of arcades in the US at that
time) developed a JAMMA interface for the PC-Engine with NEC's blessing. NEC
pulled funding for the project before mass production began, and it never
took off.
Driver notes:
- game time is controlled using software loop - with current clock it takes lots
of time until credit expires. Should Z80 clock be raised?
- tone played by jamma if board is not emulated
