Title: Do I need 2 coin buttons ?
Post by: Ed ONeill on June 16, 2004, 05:35:25 pm
Ok I am in the process of building a laptop mame machine and I have limited space on the control panel 1 player only.

It is obviously going to have 1 joystick and  6/7 seven buttons on the right of the joystick, so you can play as many games as possible. To the left I was going to put coin1, coin2, player1, and  player2, but then I started wondering......

From what I remember....the old classic 2 player alternating games (ex pacman /frogger..etc) those  wouldn't need  2 coin buttons.

Now having said that...
 Can anyone remember/name a game that I might need to have a second coin button.

Thanks in advance
Ed

Several multiplayer games need more than 1 coin "button" because depending upon which coin button is pressed determines which player will be used.

JustMichael ,

The games you refer to are they alternating 2 player games?

The only way to player 2  player games on this machine is if they alternate .

I can't think of any games that use two coin slots independently, with a single set of controls, so you should be good with one coinup.

Make sure you wire it to coin1 though.
I seem to remember a few games that won't accept coins in the coin2 slot because they didn't HAVE a coin2 slot on the original machines.

I was told only one but I just wanted to make sure .

Anyways I made a temporary control panel with both coin1 and coin2. You can see it in the project announcement forum, the thread name is "mame on the move ". I am hoping to eliminate the coin2 button and re configure the left side of the control panel 3 buttons instead of 4.

Let me know what you think

Part of my opinion here is based on memory only, but hear me out: The only games that used 1 coin switch per player were usually the 3 or 4 player games. That way, whatever slot was coined up, that player "station" would be ready for a player to join in and play.

Now, I don't know of ANY 2 player games which also did this other than perhaps some driving games like 2 player Super Sprint?

The reason most 2 player games even have 2 slots is not so that 1 slot is for 1 player, and the other is for player 2, but because it is better for "business" to have 2 slots in case one of them becomes defective, or for that matter sometimes a quarter that doesn't work in one side, works in the other. it just made more sense to the game's operator, because with one slot, if it broke, that's it, the game stopped earning money until the operator came by or someone called in to have it fixed.

What I'm doing on my cab is just putting 1 coin button.  I'm going to set a shift command on my keyboard encoder in case I run across a game that requires specific coin slots.

Example:
Coin Button = 1UP
Shift + Coin Button = 2UP

RayB and other you have settled my worry

I think I will just use one for this project.

Thanks

All NeoGeo cabinets for one...If you put a coin in on the right side, that's a player 2 credit only.   There is an LED on the control panel showing how many credits each side has.   General rule of thumb: Any multi-player game that doesn't have a shared credit pool will need two coin slots.

Since there is only one set of controls though it's a moot point.  All the 2 coin slot required games are simultaneous play which is impossible with one set of controls.  I can't think of alternating turn multi-player games that would need seperate coin slots...

Only 2 games come to mind that uses different coin buttons for that player, and their TMNT and Simpsons both 4 player games, the slot you use determines your character

There is only 1 joystick so I still only need one coin button to play tmnt and the simpsons, or are you  saying  if I want to be character 2  I would need a second coin button?
