2/3/4 Player simultaneous games

[Brad Lee]

Is there any utility or method out there that will generate a list of what games are 2P simultaneous?
Sortinfo only tells the number of players, so Bubble Bobble and PacMan both are listed as 2, even though with Pac you alternate turns

Nope... the closest is controls.dat which only has access to around 500 games at this point.

mame doesn't give access to this information...  It seems like it should be in the driver itself, but it doesn't give this information out.

also, many of these games are different in cocktail mode (pacman for example... I don't know about bubblebobble has a cocktail mode)

Closest I found in the source was that for bublbobl, it had 2 /*input port*/ sections, where Galaga only had 1. Further complicating it was that Galaga's single input port section had 2 2-way sticks, at different addresses

Also, according to sortinfo and the source, some games are listed as 4 player even though theyre only 2- puzzle bobble 2 & 3 for example

KLOV is also dodgy, as some games itdoesnt have the info for, some are listed as "competitive" etc

I didnt even think about cocktail mode..sigh
