2 Superguns I built a little while back.
« on: May 17, 2007, 10:16:45 AM »
Here are pics of 2 Superguns I built awhile back. I never posted pics of them. The bad quality pics are from my sucky web cam on the s-video one I built that I currently use for my gaming.
The high quality pics are of the one my friend had me build for him. His also has component video out on his as he wanted that also. His is using a Jrok,mine is using a asian built encoder with a NTSC/Pal switch. Both superguns support -5 volts and have 6 button harnesses. Both have been able to run any board jamma based hooked up to them as of yet. Both support NEOGEO AES sticks. I think the only thing they wont use are the NEO CD pads,if I'm right they require +5. I only wire that into the controller ports by request.




Before anyone ask,yes,the fan is held down tightly by 4 screws in the back. My friend forgot to bring 8 screws for the fan,ended up only having 6,but the grill stays on supertight with only the 2,so whatever. He can add the other two whenever he feels the need to.






The one I am using has a temp gage on the back,so if by chance my power supply is cranking out alot of power I will know from the extra heat.


Alot of people use heatshrink tubing on the harness wires. I do not,because if I have to rewire something I want to have the freedom to do so. I don't post pics of this stuff on here too often,and I have been busy with work as of late. Anyway just take it as another glimpse into the evil world of Jamma Supergun Gaming aka No Cab Required.

Looks good, man.

They look like the sort of quality work D-Lite would do!  Good job!

Ok, I have to ask, what's a super gun exactly?  Is it a condensed 'interface' to play arcade decks?

Naw, a supergun is an extraordinarily large cannon with an extremely high muzzle velocity and large bore. They were used to bombard an enemy from extremely long range and destroy heavy fortifications. :wink:

Like those 18.1 inchers that adorned the decks of the Yamato and Musashi??

LOL,actually Dean uses cases from PacTec,but he uses a different size type,much smaller,and he only uses a larger one for his full on expensive models. I actually had a person who was purchasing a Time Killers board from me once off ebay inform me they were having Dean build them the larger "Bazooka" model.

Dean was using all sorts of junk in it,NeoBitz encoder,which is known for having multiple problems with non-CPS and SNK type boards,stuff like MK and Primal Rage,Time Killers,ect, a power supply that was having issues with the encoder,causing problems with video out on Atomaswave I think it was. It was funny cause the whole time Dean was telling this guy what he was using was "the best parts possible" Dean had a thread going about the issues he was having using those parts in conjunction and the visual problems that were being caused. After pointing the guy to the thread and junk he seemed a tad unhappy,had me make a run down of cost of parts,what encoder should be used,ect ect.

It ended up really pissing Dean off.I could tell from emails being forwarded to me. He had to yank out the encoder and replace it with  a Jrok,and some other things. The 20mm fan he was using in the unit,its useless too. The guy was wondering why Dean was using such a tiny fan too. No venting and a 20mm fan will do no good pulling heat off of a heavy duty power supply. This is why I use 80mm and provide venting. Anyway I gave the guy a run down of what Dean should change.

 It upset Dean I was informed,but he did it anyway as the customer requested it. I'm not positive but I got the impression the guy was making Dean feel like he'd take his money to me if dean did not do the changes. I ended up sending a email to Dean,doubtful he read it,stating I did not want his customer. I was only making suggestions because the guy asked and because he was buying something from me also. At that time I was not able to build anyone anything. I had other things going on with my kids,so I was pretty busy. Basically the guy was spending around 500 bucks at Deans "shop" so I felt the guy should at least get his moneys worth.

To help save face Dean gave the guy a few MVS carts as "freebees" after the work was completed. Basically after the guy got the MVS carts he got his moneys worth.

Dean does do something cool,and that is he mounts things like controller ports from the inside. However over time if you unplug your stuff alot and plug it back in they can get loose and fall inside the unit unless you use mini bolts,washers,ect. Im sure he prob does use them,but who knows. I like mounting them on the outside,just my preference. He also uses RGB knobs for adjustment,which I never in my life have had to use.

 I typically set the encoder,jrok or whatever up via the pots onboard and it does awesome on any game from then on and never needs further adjustment.. It may be he uses them because of the AD chip on the NeoBitz,I am not sure.Those need more tweeking sometimes. He also uses Jrok encoders on certain projects so I don't know.

Before I run,incase anyone was wondering,it cost my friend around $220.00 to have his built by me,and the one I am using only cost me around $130.00.

Yea,they let you play arcade type pcbs on your normal tv.

Jeez, only a $130 for a supergun?  Wow I remember the main guy who used to build those would charge over $300 for his back in the day.  Jroks rule, btw, I just got mine going a few weeks ago and its f*cking awesome.

Yep,Jroks are awesome encoders.He def knows what he is doing,prob makes the best encoders in the USA s-video wise and def component wise. The reason I'm using only S-video in my SG however is because my encoder in it actually has better s-video then the Jroks. Not by much,but it does handle certain boards better and gives a sharper/more clarity driven image. My encoder works fine with Jroks sync cleaner also so I have one of his in there. Its been a long time since I had to purchase a encoder from him,as I switched to the asian s-video one,but I still recommend his stuff to people wanting to build a SG,esp if you don't want to import a encoder,and if you want the best in component video out. Kurtz can go suck donkey dick with his NeoKlutz encoders...

Michael, do you just dislike the neobitz for supergun applications (where the compatability of the ad724 would make it kinda of crippled)?  It seems like you dislike them in general. I have a few samples of the ad724 and 725, but didnt make any circuits yet. Ive heard they are pretty nice ICs when they work. I was going to actually buy a neobitz kit for my duo a while back, but unfortunatly they dont work with PCE.

Yep,I dislike them terribly. They are actually pretty old cheap ass chips. They use to use them on old PCI Trident cards to handle tv out back in 95-96. Crazearcade use to use the 725 if I remember right,and it did well enough with a few boards including NeoGeo,but could not cut it over all. Some boards it would not display right,colors would be off no matter what,or display in black and white. The 724 has similar issues and worse quality. Neither were made for all around compatibility. They are cheap chips made to be tweaked with extra components to work on a certain product really well,not to function with a wide range of items being thrown at it.

Ahh, I didnt know they were that old. I was under the impression that they were newer chips, but I suppose that explains their crappy performance. 

Michael, have you tested any of your JROK encoders with your PCE? A while back Lawrence stated that the svideo/composite board did not work, and him and jrok could not figure out why. Im just curious if anyone else has tested them with any luck.

No,I never tried one (Jrok Encoder) on the CoreGrafx or White Pc Engine I used. I was actually wondering this myself,as I believed it may be a sync issue.I knew there was a problem,was not positive it could be fixed,and I think I actually suggested someone here awhile back (Gutts maybe) should ask Jrok if the sync cleaner would fix it. Jrok makes a sync cleaner that alters the pulse also. I have wondered if anyone has tried to see if this would work. Gutts stated above he got a Jrok,but did not specify what he is using it on. Maybe he can add to this?

I love my J-Rok encoder! Just my two cents :) .

Adding PCE console specific layer on top of that, makes for an interesting challenge (no, not a reference to Ys II).

Yeah the sync was a total bitch to get working on the JRok with a PCE, but I finally got it going.  I had to build the sync amp, but even then it still wouldn't work until I removed one of the grounds, then for some reason it worked.  Whats really bizarre is that it worked with the composite video as sync at first, but the colors were really washed out, then all of a sudden it just stopped.  Even with the sync amp the colors are all f*cked up though, like red completely dominates everything and I cant fix it.
