Dual Driver MAME?
the King:
I've looked through the FAQ and didn't see anything on this, but maybe I missed it. Is there a way to do a dual driver MAME? Like, so you could race against each other and have the same game on each screen? Thanks in advance for any help.
This is what I'm working with,

I'd also like to know this as I would like to build a twin racer from scratch and integrate MAME for dual-player Outrunners etc.

Technically, I don't think this is possible in MAME because MAME is not set up for networking. You could have one screen image displayed on both screens, but it's kind of pointless to have only P1's screen showing for both P1 and P2. (Makes it pretty pointless for P2).
This is actually something that I've brought up to MAMEdev and they are looking into it. What they will NEVER do is allow over the internet play to take place. That would introduce so many issues that it's not worth attempting. What will occur whenever they code it is intranet playing. E.G. they'll emulate the network used by the machines so that you could play them properly. This would be needed for any driving game, or Super Street Fight 2 Tournament Battle.
What you would end up doing is having multiple instances of MAME running and one instance would be for P1, another for P2, and another for whatever other number of players there is. This would probably require a bit of processing power since it would be like playing multiple instances of MAME at the same time.

Surely it would make beter sense if they were to allow 1 PC to just send a portion of the display to seperate monitors. For example, right now, you can view both screens in games like outrunners on one screen together (side-by-side), or pick which screen is shown in the options. If they could make it so that you also have the option to send the two output displays to two different monitors, you could have two monitors running off one instance of MAME, one PC, but on seperate monitors.
There is of course a current solution in building a wide-screen projector based machine so the two screens display big enough to be playable by both players, though mounting points would have to be carefully thought out. You could use a massive widescreen LCD, but the cost would be stupid.

I'm sure, given MAMEDev's policies is that this would consume ridiculous amounts of CPU power. ie, given that some of the more modern games run bog slow as it is, emulating the networking layer is going to add even more work to an already busy CPU. It would take less time restoring said cabinet than it would waiting for MAME to catch up.
Not trying to start an argument here, it just doesn't strike me as prudent having such a massive cabinet sitting around doing nothing.
