Author Topic: insert coin (joust) strange problem (Read 2351 times)

MiKman · « **on:** July 16, 2004, 06:52:27 pm »

I have this strange problem only seems to be with joust. The coin 2 button (6 on the keyboard) gives 4 credits. On all other games it gives only 1 credit like it should. Anyone else notice this? using Mame32 0.84. I also deleted the joust.cfg and the default.cfg files but no difference...

Any ideas or is this happening to everyone? Could it be this is the way it's supposed to be?

Thanks,
Mike

Yes, Joust gives me 4 credits too on Player 2 credit. It also happens on the other Williams games I play - Defender, Stargate and Robotron. But not on SmashTV.

That's because these Williams games assume you're using a three slot coin door. The left and right are a quarter, and the center slot is a dollar. Check it out in game settings. Better yet, here's a screenshot:

Interesting, must be a bug in the williams roms or maybe mame itself... I should get to my local arcade and play some williams games, making sure I put my quarters in the coin2 side

Nope, not a bug, the center slot is for dollar coins. I've got one of those Williams doors around here somewhere.

Peale is right, it isn't a bug, it's the way the cabinet is wired to the game.

So I guess if I want it to function like a single quarter for williams games I need to change the coin2 button (in the tab menu) to 7 instead of 6. Thanks for the information guys I had no idea I guess I can't remember that far back when I used to play joust on a real cab that it had three coin slots...

SirPeale · « **Reply #7 on:** July 17, 2004, 04:38:37 pm »

Nope, that won't work either. Those games have only two coin inputs.

I started a thread @ mameworld regarding this, just waiting to see what comes of it.

quarterstringer · « **Reply #8 on:** July 17, 2004, 05:32:22 pm »

I figured out how to change it to 1 credit.

Start Joust or any other Williams game.
Hold F1 down and hit F2 twice
You'll be in the menu
Go to Pricing Selection - Change to 0
Then change Center Slot to 1
Hit F2 to exit.

While you're in the menu, you can also set your own personal attract mode message.

That 'kinda' takes care of the credit problem. I mean, yes, now it will give one credit instead of four.

I just wonder if MameDev will make the coin inputs correct.

quarterstringer · « **Reply #10 on:** July 17, 2004, 05:47:55 pm »

Yes, it would be better if the coin inputs were correct. Also, I couldn't figure out how to change Defender because it has a different menu and I don't know which key changes the values.

SirPeale · « **Reply #11 on:** July 17, 2004, 06:29:58 pm »

Defender is the same keys.

SirPeale · « **Reply #12 on:** July 18, 2004, 08:40:01 pm »

Well,a couple of MameDev have looked at the thread on the MameWorld forums, and really don't appear to care either way. R. Belmont is more concerned over my avatar than accuracy.

*shrug* Well, maybe the three coin inputs will get in there, and maybe they won't. Hey, the source is available, maybe someone here will make a patch.

SirPoonga · « **Reply #13 on:** July 18, 2004, 10:45:53 pm »

Haze might be right. The physical coin door might have been wired to 1 input. Check out wire schematics and/or instruction manuals and see.

MiKman · « **Reply #14 on:** July 18, 2004, 11:00:21 pm »

ahh well I was just worried I did something wrong thanks for all the input and assistance. At least we know whats up now, whether or not it gets change, at least I can work around it

SirPoonga · « **Reply #15 on:** July 19, 2004, 12:27:40 am »

Why would it change if it is correct? Like I said, you gotta look at the wire diagrams and instruction manuals to see if both slots in the coin door are recommended to hook up to one input.

SirPeale · « **Reply #16 on:** July 19, 2004, 09:20:07 am »

Well, I found a Joust schematic online. There's three inputs for coins, left center and right. I'd link it, but don't want to kill their bandwidth. Easy enough to find in a search, though.

I'm sure other games are similar.

I tried hacking in the support myself, and successfully got Joust with three coin inputs. Unfortunately the third slot inputted FIVE credits. Yah, I'm no emulation programmer!

Edit: I got it, and it was easier than I thought.

Edit2: I *didn't* get it. It was registering the left coin input twice.

SirPeale · « **Reply #17 on:** July 19, 2004, 11:38:04 pm »

Fixed it. Carlos Santillan noted that the servce button doesn't actually work, it triggers the right coin slot. So, moved some code around and now:

Left slot - 5
Right slot - 6
Center slot - 7
Reset high scores - 9 (it was 7 before)

SirPeale · « **Reply #18 on:** July 20, 2004, 01:28:00 pm »

I submitted the new driver to Gridlee. Whether or not it makes it into the next release is up to him.

SirPeale · « **Reply #19 on:** July 20, 2004, 04:06:43 pm »

Oh, if anyone wants it for themselves, it's on my website.
