I am starting a bartop build, and I am wondering if I actually need two coin buttons. On my upright, it seems that every game I have tried so far will let you add money through the coin1 button, and then still start a 2 player game with the 2up button. Are there any 2 player games that actually require the 2nd coin slot?
Thanks!

I am more then willing to be wrong on this, but if memory serves me right it really only seemed to matter to games like "The Simpsons" and "Teenage Mutant Ninja Turtles". On games like that it mattered where you put the coin as to what players you could select.
Also I have noticed on some games that if I use the second coin slot it will add more then one credit. I am not sure what that is about though.
It has been a while since I really thought about this issue so again I could be wrong.
-
Depending on the software you're using, you could remap one of your other buttons or an unlikely to be used combination to be the second player coin. Just a thought.
-
Various beat-em-ups tend to have it tied to coinslots. How about using 24mm buttons for the start/coins to save some space?

This particularly for the Midway games like Robotron, Sinistar, Defender etc....... Because it has 3 COin Inputs.

You need to change some configs on MAME and the GAMES (F2) to get what you like...
-
If you want to play Gauntlet or Gauntlet 2, you need separate coin slots for each player. 4 if you have a 4 player setup, or you could use 2 and use the 2 player ROMs (which let you select the character on Gauntlet, something you couldn't do on a 4 player machine)

The Konami beat 'em ups have 2 player variations. There's no reason for anyone with a 2 player machine to use the 4-6 player versions.
I have coin mechs, but I also have a hidden coin button. Only really need one.
-
since this is just for HOME and for FUN, if you have 1 coin slot in your bartop, you can just change MAME, so that when coin is drop in slot 1, it gives P1 & P2 1 credit each....or like mentioned above, just have separate buttons for credits.
-
RAMPAGE for sure need separate coin entry.....
-
No, surprisingly rampage has a common credit pool that the 3 players draw from. Kinda dumb IMO.
-
Thanks for the information folks! I wanted to use one of those nice lighted fake coin drop buttons from GGG, so it's nice to know I can get away with just one. That will save a little space. I also like the idea of adding credits to P1 and P2 every time a credit is added.
Thanks,
Rob

Simplest solution:
Use the shift functionality of the IPAC to assign a shift function to the coin slot. If you have a situation in which P2 needs a separate credit, assign a shift function that uses the shift button + the coin switch to add a coin2 credit. That's what the shift function is there for people!

I like Shardian's idea. That way, you don't add extra credits you don't necessarily want, but yet you can get credits for each player. In Gauntlet, for example, both players might not want a credit, if player 1 has a really good score and alot of health and player 2 is almost out of health. (in Gauntlet, the score is divided by the number of coins for the high score table). Moloch is correct, Simpsons also uses separate coin slots on the 4 player version. On the 2 player version, it lets you select the player when you start a game. Teenage Mutant Ninja Turtles uses separate coin slots too. I assume the 2 player version lets you choose players like Simpsons does, but I don't know for sure.

I did something somewhat similar to shifting for P3/P4. I actually installed 2 small momentary SPDT button switches from Radio Shack on the underside of my panel (it's a metal panel). The wire from the coin switch runs to the common terminal on the button, and the 2 switched terminals run to player 1 and player 3 start (or for the other button, player 2 and player 4). That way, if you normally drop a coin it applies to P1, but if you push the button while dropping the coin, it applies to P3. Essentially an "external shift". I didn't want to use my IPAC's shift because when you're in the middle of Gauntlet or The Simpsons or whatever and need to insert coins for extra life (and everyone else is still playing) hitting a shift on the main part of the CP isn't so convenient.

I remember 6-player X-Men had 6 different coinslots, 1 for each player.

Well yeah, but there's also a 2-player variant.

Can't you also just assign 2 functions to the p1,p2,p3 and p4 buttons? Just configure the corresponding credit to the corresponding player start button. who cares if you have a few extra credits by hitting it extra times.
-
I don't understand what you're getting at.

he means map start and coin to the same button
-
That makes more sense. I saw it as 2 functions to all four player start buttons and was confused.

Use the shift functionality of the IPAC to assign a shift function to the coin slot. If you have a situation in which P2 needs a separate credit, assign a shift function that uses the shift button + the coin switch to add a coin2 credit.
I would do both of these... Assign coin1 and coin2 GLOBALLY in the Tab menu in MAME to the same credit button. Then on those few games that depend on certain coin slots for each player, in the tab menu for that game only you can manually assign the coin 1 button to be the credit button pressed by itself, and the coin2 would be the shifted credit button you assign to it.
