Coin Buttons?

[froggerman]

How many people have coin buttons on their control panel even though they have working coin doors? Any specific reasons to have them or not?

i have mine is hidden (for me and for the kids only) but mostly i tell ppl where the secret coin credit button. But usually if I'm not around, they shove in quarters to play

Some people have the credit triggered so that when you press in the coin reject, it gives you a credit.  I think this is a pretty neat way of having both a coin door and a credit button.  To do this, they just have a switch that gets set off by the motion of the coin rejector.

Yeah, this is the way I set them up.  Pretty slick way of having it both ways.

at first this is how I did it. It just became to annoying with that reject button.

Yeah, that's what I did too.  The way my coin mech is set up, there's a small hole in it that's just big enough to stick one of those mini momentary switches from Radio Shack in.  I put one of those in there, and it gets pushed whenever the reject button is pushed in.  It works rather well.

On my dedicated Karate Champ I have a button in the lock hole of the coin door.  The coin slots still work.  I have a wad of foam tape inside to keep the door from flopping open.  This way I can just put a lock in and sell it as 100% original when/if I decide to.

The IPAC has a shift function that allows you to do this without the need for a dedicated button. Out of the box it's something like player one start + player one button one. I can't remember for sure because I never use that funtion. I like dropping tokens in the coin slot!

hmm, i never thought about using the shift function for coins.  so you hold down player 1 start button, and push like....one of the buttons for player 1 and it gives credits???  that way i could take away the coin button on the cp (dont have a hole drilled for that yet luckily) and just make it look like you have to use quarters    can you confirm this in more detail?

Yeah it works something like that. Like I said I never use this function so I don't remember the exact combo. Whatever it is you just hold down the player one start button and then hit the other button that has that shift function assigned to it. You don't even have to reprogram the IPAC to do this, it comes that way straight out of the box with the jumper set to MAME.

I think that is actually the deafult IPAC programming set-up so that shift and player one button one is mapped to player 1 credit (which works for all players for 95% of games)

Heh, the thread has deviated a bit from the original question...

IMHO, having a coin door was mainly for authencity.  Also, I thought it would be  a cool piggy bank.  I wasn't really going to charge friends and family to play, I just wanted it for me.  I don't get the same satisfaction pressing a button then I do dropping a coin in (I guess I like to hear the sound of the coin dropping on top of the other coins .   )

yeah but when your friends are cheap ---daisies---, then you dont get to hear that sound too much!  

but will this shift function also work the exact same way for players 1-4?

I know I am off the topic buty can anyone tell me  how to make the coin reject button trick work...Like what parts I need from radio shack , and picture would be great

Thanks

Here is what mine use to look like.
You have to use the Plastic Mech with that (look at red arrow) bend/bowed and when you  push the reject, it bends over to push the microcwitch. I just stuck this back on for your pic, but I no longer use it. It was to much of a pain IMO.

As far as this idea with the ipac, you can do this with just with MAME. All you need to do is:
TAB
INPUT GENERAL
select COIN#
hit Enter
quickly select the 2 buttons you to use (5 then P1button1)

so it looks like

COIN 1                  5   Whateverbutton


Now when you press this 2 buttons together, you get your credits.
There's really no need for SHITFTING

[hulkster]

oh okay, so just push both buttons at the same time when looking at the menu in mame.  is that all?

When you and your friends are close to beating a game (like metal slug) Press P1Start and P2Start at the same time.

I recommend either disabling the shift function completely, or reprogramming it (Default for P1 and P2 is the escape key... which exits the game).

3M makes a double sided tape (about an 1/8" thick) that works great for mounting a microswitch behind the coin reject buttons (I tried hot glue, and got sick of reglueing).

For certain games I have button #7 (that mostly usesless, extra NeoGeo button) mapped as a coin button. There's also buttons on the side of the base that were originally intended for pinball, but thats the same as reaching for the reject button.

Does it? Yikes! I use MacMame. Esc just pauses the game and allows you to access menu items in this particular MAME flavor. If Esc exited the game I would disable the shift function too!
