super gun question

[billcosbymon]

Does any one know of an up to date on how to build a super gun? If so, I would really appreciate it.

I used a combination of this http://www.jabba.demon.co.uk/retrora...a_test_rig.doc

and this http://gc339.free.fr/JPEG/SuperGun.jpg

I build mine a couple of years ago now. still works great

I wasn't aware you could be out of date on this. It's the same process it has always been. Provide your board with Power from a PSU, connect Input, connect Outputs. Put it all in an enclosure.

You don't really need a step by step. Infact I think it'd be harder to make one if you were to follow some step by step guide. Given that you are in the US you'll unfortunately need a video encoder unless you have a RGB monitor.

Sorry I'm new to this type of stuff and yeah i dont think ill find a RGB monitor easily in the us. I was just saying because maybe new and cheaper video encoders came out.

[MottZilla]

I'm not sure there is anything new in that respect. Your primary choices are the JROK and NeoBitz. Or building your own making by removing an encoder from a game console.

I know this may be a stupid question, but what kind of wire should I use or should I just use a pre wired jamma harness and how would I install a kick harness for the 3 extra buttons?

[MottZilla]

I would buy a prewired JAMMA harness. It saves you alot of time.

About auxiliary button inputs. What I did was got a terminal block/strip with enough spaces for it to hold Start, Up, Down, Left, Right, B1,B2,B3,B4,B5,B6,Ground. I wired the standard JAMMA inputs straight from the harness to the terminal block which connects to the controller port (or could connect to your control panel). The buttons 4,5,6 I had connected to another terminal block which on the other end I connected kick harnesses for each game I would use. Also since I used NeoGeo alot, I also connect Button 4 from the JAMMA harness straight to the controller port.

Another thing I did, since my controllers are SF2 layout of two rows of 3 buttons it made things annoying for NeoGeo. The layout being:
123
456

Which for NeoGeo meant:

ABC
DXX

So I installed a switch in my Supergun that would connect buttons 4 and 6 together. That way it would be like this when the switch was on:

ABC
DXD

I also played Mortal Kombat 2, so I had another switch for that game. Normally it would be like this:

HP Block HK
LP Nothing LK

So I made a switch to would connect button 3 to button 5 to get a second block button on the bottom row.

Hopefully you can figure out what works for you.

Thank you :-)

i would stress on buying a new one rather building it (actually trying to build it) without technical knowledge

[billcosbymon]

My dad is very good with this type of stuff i dont think ill have any problems. He taught me how to solder lol.

[MottZilla]

Building one isn't very hard at all. Basic skills are needed to solder wires and such together. As long as you follow good instructions you'll be fine. The hardest part is putting the components into a enclosure that you will like. Wood tends to be the easiest material to work with for most people. Also if you get a pre-wired JAMMA harness alot of the work right away is done for you.
