The port definition in the driver states the size, and MAME converts it. Why would you want to redo the work in 1000s of drivers?

I would recommend to study the code and drivers to understand why it does what it does.


Do not p-mail me for help compiling my updates, ask on the board.
Do not request sound for your favorite game. I work on whatever, when I get around to it.
If you have schematics for discrete sound games not easily found on the net, I would be interested.
