Supergun help

The Last Bandit

Looking for help testing out a new Supergun design. I've the PCB finished, about to pull the trigger and order a batch made but would like the firmware to get a hammering as well so have prototype ready for 'field' testing

Need someone with a few different Jamma PCB's and a eye for latency

I needed a supergun but wasn't impressed with what was available (and some have fundametal design issues IMO) so built my own.

One of the main differences between this and other superguns is in the handling of the audio. Jamma audio output is fully isolated for your boards protection and not shorted to ground...

Switchable between Mono/Stereo/MVS and Line-in audio

Intergated kickharness support for 6 button control schemes

Supports several different controllers types. (Sega Saturn, Sega Megadrive 6-Button, Sega Mastersystem, NES, SNES, PC-Engine/Turbo Grafx, Atari, Playstation and NeoGeo)

I've tested this out with my own boards (Neogeo, Hyper 64, Namco System 11, 60-in-1) and everything works fine but would like to try other boards and other controllers models.
The prototype is fully cased so not likely to burn down your house or get your pets pregnant etc etc..

It'll be worth your while and being able to use a Saturn controller is simply awesome

Do I get to keep the supergun as payment? :pac:

Sounds like a great bit of kit.

The Last Bandit

Yes

You interested ?

I'd love to try it but o1s1n has a vast PCB collection, lets hear the review and then you can sell them to us all!

o1s1n

Sounds interesting

As long as you can guarantee 100% that none of my boards will be damaged then yeah, feel free to drop by sometime and try a load of them out.

The Last Bandit

Cool beans..

Ya your boards are safe enough alright, but playing Metal Slug with a 2 button NES controller can be damaging to your sanity

The Last Bandit

See no smoke

Looks nice!

Reckon you'd be able to wire up an arcade psu?

The Last Bandit

Ya can do, just need to add another external lead for -5V stuff.

I don't think you'll get that guarantee from any system; supergun, cab or otherwise. My advice would be to plug in your cheaper boards first, or the bootlegs. :P


@Last Bandit: That looks slick dude, excellent work. What is the display on top for? Presumably it's RGB SCART out? Does it have or need RGB adjustment pots to alter colour levels? The ability to plug in Saturn and PS1 controllers is great.

The Last Bandit

Display on top is a voltmeter on the 5V supply, had a few spare so stuck one in but its a bit pointless with the ATX power supply as its not adjustable
Video output is RGB via a SCART plug at the rear, there are pots internally to adjust RGB levels alright if needed.

Yeah Saturn controller is definitely one of the best ever made

o1s1n

I thought that looked like you'd stuck a voltmeter on top. Brilliant idea.

Sounds to be leagues ahead of the last home made supergun I bought.

CathalDublin

I've a taito BB, load of bootleg horizontal boards and a mvs of you need a hand testing

CiDeRmAn

What do you think you're going to sell these at, when the time comes?

Depends on how much the pcbs cost to get made, only building a proto batch so they cost a bit more.
Rough guessimate would be 100 for the assembled board I think.

Keeping an eye on this great work bandit well done..

brianon

Aye. I'd be interested in the first batch to be sure. Have mvs and two jamma pcbs.

The Last Bandit

Many thanks to O1s1n for letting me experiment with his collection of boards today

Happy with the results, just a PSX controller bug to fix and we're good to go

o1s1n

No worries dude. Nice to see they're all still working

Your supergun really is looking great. All the best with it, I can see them going down a treat!

brianon

How many superguns does one need to own before one believes he has enough ?

Looking forward to this one

Maybe I am stocking up for the end of the world. At the end of the world a Supergun could rule!

The Last Bandit

Added support for 3 button Megadrive and that weird ass Dual Analog PSX controller this morning.

Also noticed a really stupid error on the pcb as well Typical, proto pcbs have been manufactured/shipped and then I spot the error...Easy to rework but annoying as hell..

brianon

When are you taking orders

The Last Bandit

And it lives Few teething problems, somehow the switch footprint doesn't match the switches I bought so had to improvise a bit. Should all be fixed in the next spin although with new thumb-pots and switches.

o1s1n

Fair play man, looking good! You'll have a production line with people assembling these within the year

What sort of controller ports are they Last Bandit?

The Last Bandit

Controller ports are D-Sub 15 so Neogeo controllers straight in, but with the relevant adapter cables you can use different console controllers - up to 8 supported now. The chips behind the controller ports does the translation between Jamma and the console controller protocols.

Ya the red boards are worth the extra costs alright

What are those kick harness connectors called?
and where can i buy them?

The Last Bandit

Those connectors are JST XH, I got them from Farnell .

The Last Bandit

Finally finished the new version. Couple of minor new features but more or less the same as the original version. Coming soon to a 'for sale' thread near you.....



In action with Sega ST-V board, stereo audio taken from board into 'Line-in' jack and kickharness attached (even though I've only 3 button games )
