This guide any good http://dasfool.aroo.tv/Index.html

I'd buy one but it's like $300 for a decent one, figure this will be cheaper.

Hopefully excellentcom still has strikers 2 in stock when I'm finished :P

Buy Strikers 2 first.
1) It gives you some motivation to finish the supergun, as you'll have to stare at your unuseable strikers 2 board.
2) It gives you something to use to test your supergun as you go.

damn, I don't think i'll ever have the time or skillz to build something as holy as a supergun, where is it that people are selling superguns?

about the only places I can find that sell them are all PAL. I'm in the us and eventually going to Japan sor NTCS is what I need.

Neon - Yes, that guide by dasfool is suitable. For purchasing, www.therealbobroberts.com is a great source for quality pre-made JAMMA harness and other misc. parts.

zakk - Agreed. Get some PCB first before assembling.

scrilla4rella - Since you are going to Japan, might be better to wait till then and find the supergun made by Sigma, etc (or if you know someone who will buy it for in Japan...just as well). You can find them at many PCB shop over there. The ones made in US, like MAS systems, are not good quality.

example of current Sigma and other JPN made supergun: http://www.mak-jp.com/ctrbox.html

I started a supergun project about 8 months ago.

I bought the project box from Radio shack, bought a bunch of DB15 ports (compatible with neo geo sticks), got a few RCA jacks, A jamma harness and made my way to gamesx.com for pinouts on the neo sticks.

I got about 75% of the way through it and gave up. Last week I sent all the bits and bobs to a guy called Scott Fish who is finishing it off for me. I just didn't have the time to finish it myself.

Since then he got back to me and told me that my RGB to component transcoder was one of the best he has seen, so I am really anticipating taking delivery of my baby next week. So far its cost me about $130 in supergun parts, the transcoder cost $160 and it is external because I want to use it for consoles as well. So I can play SNES/Genesis/Neo geo etc through Euro scart leads to a component TV. So I am really happy at the moment.

Its a shame that in the USA you need a convertor box for the RGB signal. Because even if you use Svideo or composite your looking at least $90 extra for that functionality.

I tell you something else as well, if you don't have the correct tools or have no experience, you can add approx $50 more. Some of the buttons, switches and RCA jacks are expensive if bought in small quantities.

For the ultra simple aproach, just get your hands on..
Power supply
Speaker (a car speaker works great)
video decoder (that one from the first link, modded from a PS2 cable was the best- I have one of those that someone here made me and it works great)
2 Circuitless controllers (which you can mod from anything)

.. and then just wire it up according to JAMMA. If you just want to solder everything together, it's super easy, and the more plugs and knobs you add, the better (like volume knobs, extra volume outs, fancy connections).


Here's an easy diagram- it's even easier if you read it in reverse

Power supply with 5,-5,12v-----------------------------Jamma
Speaker------------volume pot-----------------------jamma
video decoder w/RCA out--------------------------------jamma
Controller-----mod w/new wires----------------------jamma

could it be that the site you linked to is incomplete? I tried it yesterday, and again just now, but when I try to access "video" under "assembly", I get to an empty page.
I dig the approach, though, basically I did the same: first connect all the power cables. That´s the most important part by far, making a mistake here could easily destroy the PCB. After that, going step by step and checking it every time is a good way to minimize errors.
Like dpful suggested, my first supergun also didn´t have any plugs, sockets or features. The important part is to get it working at all, and every additional feature can create additional problems, so it´s best to start as simple as possible, check whether everything works, and then build upon that. You don´t even need a box necessarily. Just make sure to solder carefully, heat up and pre-solder every connection before putting things together, and make sure everything´s well isolated. Don´t use extremely thin or long cables, rather a little thicker and short, because length and thin-ness can act as a resistor in the circuit. When everything works as it´s supposed to, you can still swap the cables for longer ones and see whether it still works.
Ideally, you should try to find someone who has a working cab or supergun and check your PCB with it before you start building. If your PCB happens to be damaged, you could waste endless time trying to fix something.
If you mod a controller for a console that you still want to use for that console, be sure not to connect it to the console when playing. Circuits need to be isolated from another.

superguns are as hard or easy to make as you want them to be,
I still haven't put together a nice one, when I first made one all I had was a computer PSU, an old jamma harness, a 3" speaker and luckily an old amiga monitor with rgb inputs.

for the controls I bought some parts from happ and folded the top flap of a pizza box in half and used a pencil to punch holes that the buttons and joystick screwed into. :lol:

Not to freak you out, but from so much experimentation I slowly hurt and damaged my first prized jamma board, I think the computer PSU's I used may have been a bit too high on some voltages, I'm not sure.

It's definitely good to have a pcb around to test with, but maybe you should consider getting a cheap game along with strikers, and cheap I mean 10$ or less (like double dragon or bad dudes vs dragon ninja or something), I had a mk2 board I tested with, but I still managed to damage a 220$ game I had been trying to get forever.... (this was like 6 years ago)

D's comment is aimed at the fact that this thread is ancient.

Anyways, you can find a surrogate buyer to get you a Sigma from Akihabara. The absolutely cheapest they will run is 35,000 with gun, controller, harness, and video cable. It does not include some other goodies you might want (S-Video cable @ 2500 yen, Playstation cable for the controller @ 4,000 yen, RGB cable @ 3500 yen).

Shipping for all of the above to the US will run roughly $100 unless you go by boat.
