"Request for programming change in MAME

<< < (3/3)

JustMichael:
I understand what you are saying now but the official Mame will never do this.  This is because Mame's purpose is to document arcade games.  Since the original game didn't function this way, Mame doesn't either.  Also since Mame just acts like the hardware, it wouldn't be able to do it either.  You would have to modify the original pacman code.    It is the pacman code that looks at the player 2's joystick.

Ahh, the players don't need to know, but mame does.  And mame usually doesn't know whose turn it is.  (I'd say never, but if I did someone would find the one instance that mame already tracks the player, if there was one. ;D )
The game knows who turn it is, but mame doesn't.  Remember that mame is just faking the arcade hardware, and the arcade software (the ROMs) runs the game.

Since mame usually doesn't know whose turn it is, you will need to add that ability to each of the drivers.  One setting in mame wouldn't do it.

And as JustMichael said, since the arcade didn't do it, mame most likely wouldn't.  I can almost see it as a cheat, except for the fact that you will need to edit 1500 drivers.  (Cheats are all about finding were in the game's memory data is stored, and since the game tracks the player playing somewhere in it's memory, you have to find where in the memory that is stored, hence my almost a cheat opinion.)

Right, I thought it unlikely that it would make it into official MAME.

One thing that puzzles me in further testing.
