The 5 hours that some of the lads in Kevin St used to sit on Bubble Bobble for a single credit probably undermines the earning potential of the cab somewhat.
I can see them emptying the cash box at the end of the week and finding about £4.80 in it!

Probably took a lot of credits to build up to that skill. I used to be able to 1cc Time Crisis 2 but I sure spent a few bob attaining that title.

Finally a mystery solved!!!

I've had a Mercs PCB for ages but haven't been able to get 2 player working. Nothing to do with the controls, it just wouldn't coin up.

The manual didn't really help either

Turns out you've to have the switches 4,5, & 6 in dip switch bank B ON to get players 1 and 2 to coin up from the same coin chute/service button.

Otherwise it's waiting for a separate coin shoot.

Anyway, it works now. Can play it two player!

You could make up a splitter harness and play 4 player on 2 cabs

Fairly east to do!

youd need 3 friends tho..................:D:D:D

o1s1n · 14-03-2014 12:23pm

Mercs 4 player? you sure you're not thinking of another game

There's the option for a player 3 via the kick harness.

I wonder would it be possible to create a CPS1 kickharness > Saturn controller adapter?

You could then give player 3 a Saturn arcade stick. That'd be a cool little project.

I'd only need 2 friends then...

If your circuit reading and soldering skills are up to scratch here's a schematic I found for you:

Should be fairly easy to do actually

o1s1n · 14-03-2014 12:52pm

Name your price

I wonder would a Saturn controller port fit in a seimitsu button plug?

Would be fairly excellent having the player 3 port on the control panel

The Last Bandit · 14-03-2014 1:51pm

Leave it with me, shouldn't cost too much. Basically just a rewire job on one of the supergun chips.
Don't think the saturn socket will fit in the button plug though, will check the size.

o1s1n · 14-03-2014 1:58pm

Thanks!!!

I looked up the kick harness pinout for player 3 on The King of Dragons and it's exactly the same, so should work for that too

The Last Bandit · 14-03-2014 1:59pm

So I charge twice ??

Still have Urbanledges KoD, so I might even be able to test it out...

14-03-2014 2:04pm

Yeah take your time with it.
Didnt know KOD was 3 player!

14-03-2014 2:16pm

**** it,
sending that polo chassis to gunblade.

Possible to convert to serial and back again? A serial port should fit in a standard button hole.

Possible alright but you'd need a second chip to deserialise the data back to Jamma again inside the cab so driving up the cost and complexity.

Might use be able circular DIN instead to passthru the cabinet and controller adaptor cables same (as on the supergun) so different types of controllers an be used, not limited to Saturn alone.

14-03-2014 2:41pm

now your onto a winner Bandit!
A n64 port would fit?

o1s1n · 14-03-2014 2:50pm

How about the PC Engine DIN connection? I think it uses an 8 pin mini DIN.

So you could plug a PCE controller straight in or else build controller adapters for it

(plus mini dins are fairly standard, so no hacking required to get controller ports)

The Last Bandit · 14-03-2014 3:01pm

The number of pins in the DIN really depends on whether you want the ability to use different controllers or not.

An 8 pin DIN would work fine for a single controller type adapter and would support either a PSX, Saturn, Atari, SNES, NES or a PCE

Megadrive would need a 9 pin DIN

And on the supergun I use a couple of extra pins to figure out what type of controller is connected so ideally a 15 pin or 13 pin DIN is need for the whole lot.

Now things are getting complicated

o1s1n · 14-03-2014 3:06pm

So if you were to use the 8 pin mini din, could we could have PCE going straight in without any adapter and with a Saturn adapter you could support a Saturn stick too? That's all I'd need really

Or would you still need the extra pins to detect the Saturn input?

The Last Bandit · 14-03-2014 3:14pm

You need another pin to detect whats plugged it. Plenty of 13 pin DIN stuff available though and they're the same physical size as the 8 pin ones.

What size are the semitisu buttons ?

All the hardware work for this is already done, so its really a case of making up a simple neat solution that's easy to install and remove from a cab.

o1s1n · 14-03-2014 3:47pm

Here are the ones I have in mine, they're 30mm across.

As for a solution, could be more or less the same as FrancoB's headphone yolks.

So you cut a hole in a button plug, feed a few MM of the adapter through and use something to screw it down.

On his one, the headphone jack has a couple of screw threads on the top and a metal ring to screw it down to the CP.

o1s1n · 24-03-2014 12:06pm

I love Domy Jr. cabs. There's just something so unique and excellent about how they look.

Imagine my utter horror when I saw this.

What the actual fcuk?!

Looks like it was saved by one of the guys on AO. The insane original owner was going to throw it out!

CathalDublin · 24-03-2014 2:14pm

Thats Brilliant, is there actually a 4 player 7 button game to play on it, or is that for 4player N64 games?

o1s1n · 24-03-2014 2:30pm

That's the ridiculous thing about that (and most) of these monstrous control panel home made jobs.

Something like Knights of Valour supports 4 players and 4 buttons, but I can't think of anything which requires more buttons than that.

X-Men can be up to 6 players but only uses 3 buttons.

24-03-2014 3:39pm

when people get asked why they went with so many buttons they always say they want to play N64 games etc!

Getting the polo chassis back off grant this week.
Turns out I'm a fool that can't count.
I replaced the CRT socket with a 9 pin one instead of an 8 pin. This shorted the red gun causing it to be on all the time aka red screen.

Besides that he replaced a few caps and the HO transistor and fixed up a few other bits I bodged. He said it's running beautifully!

He also went easy on me. £47 posted back to PM
Gotta be worth it considering the stress this **** causes me and I constantly invite it on myself!!

By the way the 9pin socket fits in perfectly and even has a hole for the extra pin on the neckboard!

TechnoFreek · 25-03-2014 9:41pm

Just launched my chassis over to him a couple of days ago via parcelmotel. Was wondering how to manage the return.

Parcel motel all the way urban? Does he charge much on top of his own charge for UK postage?

25-03-2014 9:49pm

It actually came to 12pounds in the end with insurance.
He said he only uses curriers as he can't get to a post office.

I like this Jamma Snes :

Managed to squeeze a Saturn controller socket into a Happ 28mm button so should be fit it into a 30mm button. Having the actual saturn socket fitted is a bit handier as no adapter cable is need, can only use a Saturn controller but seeing as they're so awesome shouldn't be a problem

You absolute legend! Should work perfectly with the Saturn stick you fixed up for me
