Undamned's USB Decoders (USB to JAMMA, etc.)!

Hi @Undamned, I had a troubleshooting question I was wondering if you could maybe shed some light on

I recently got around to building my Supergun setup using this board http://retroelectronik.com/en/supergun/145-supergun-progamer-arcade-jamma-autofirevoltmeter-included-5674864654514.html I tried using one of your Undamned DB15 USB Decoder with the latest update.

For some reason, every device I tried with it, the top 3 buttons are all fine (p1, p2, p3) but the botton 3 are (k1, blank, coin). k2 is for some reason the home button and k3 is nowhere to be found. I tried to remap the buttons via the instructions in the PDF and it didnt work. I tested this issue on a xbox360 official controller, Madcatz te2+ (ps4 and ps3 mode), Hori Rap3, Brook universal board, ps3 official board, and a madcatz te round 1 for xbox and they all had the same issue.

Any ideas? Do you think it is the supergun board or should I try reinstalling a different firmware from your site? or should I get a UD-USB Decoder and try that?

Got pictures of your setup? Most importantly how you wired up the UD-USB to the Supergun.

The UD-USB doesn’t inherently “know” which button is what function; all it actually does is splits the signals from the USB controller; it might just be where you connected things…

@FreedomGundam I am out of town atm but I can post pics tomorrow when I get back

But basically how my setup is atm, I just plugged in the Supergun right into the Pandora’s Box 3 board directly, I didnt use a Jamma extension cable.

As for the the Undamned DB15 USB Decoder (https://paradisearcadeshop.com/undamned-usb-decoder/1551-undamned-db15-usb-decoder.html), I just plugged it into the ports on the left hand side of the board http://retroelectronik.com/506-thickbox_default/supergun-progamer-arcade-jamma-autofirevoltmeter-included.jpg

The ports are neo geo compliant with the option to be 6 buttons according to the maker of the board (http://www.retroelectronik.com/img/SNK_NEO_GEO_PAD_JOYSTICK_STANDARD_PINOUT_FR.jpg).

Hi Undamned,

Will Akihabara shop be getting anymore stock of the terminal blocks?

@Beatrush
I just had a look at the pinouts between your Supergun and the UD-USB, and there’s a few discrepancies.

That would explain what you’re seeing.

@FreedomGundam Ahhhh good catch, that looks like that is the issue.

Hmmm so I guess the best solution is to rewire a neo geo cable? how difficult is that?

Not really that hard. If you can do basic soldering, its easy peasy lemon squeezy

Got the screw terminal version on the way… I was wondering how i would go about wiring it up to a jamma harness to a Super Gun that a friend and I are building…

I think i got it, thanks for your help guys!

Hey all, I’m at kinda a loss here as to what’s going on with my encoder here.

I am installing the terminal version into my old MAS supernova supergun and as far as I can tell I should be done and good to go but both my start and 1k (short/4) buttons are not working at all. Logically every wire seems to be where it should be, if I remove the 1k wire from the 1k terminal and touch the ground terminal with it, the 1k comes out fine. but screwing the wire into the terminal does nothing. Exactly the issue with the start button, works when touching ground directly, nothing through the terminal on a usb joystick.

I wired the pcb simply by cutting the original controller port wires and running them through the converter on the way to the port. When a supergun stick is connected directly through the port oldschool style all the buttons work fine.

Any help would be super appreciated.

Tested with a hori hrap3 and a brook universal pcb.

Has anyone tried a (SNES->USB adapter) that will work with the USB decoders?

My friend has a HORI SNES pad and he’d like to play on a UD-CPS2 with it.

Is there an update compatibility list kept anywhere?

Specifically wondering if the Qanba Obsidian works with the decoders.

Thanks in advance!

Do the Undamned DB15 USB Decoder need to be conected to the supergun port if i whant to update the firmwere? I have conected the usp cabel and open the Windows bootloader application . And then hold the test button but nothin hapens. I have tryd on 2 DB15 USB Decoder same thing. i got the same message Divece not detected.

Yes, you have to power them up, and they get no power unless it’s connected to a system.

Ah tanks. =) I was afraid both was broken. I thought it got power from the usp cabel

Can anyone confirm if the inpin ps2 to ps3 adapters work with the DB15 undamned boards? Wanna have psx available for Tekken Tag 1 setup casual on my supergun.

Finally was able to confirm both of these. Looks like pad players can use their ps3 pads for the tourney

Inpin w/psx pad did not work
DS3 w/cable worked

Is there any lack of power issues with running a stick to udusb to mc cthulhu or genesis pad? I bought the stuff from PAS last night and I just need to know if there are any issues with the PCBs not getting enough power and can I use an external power supply of some type to put it to the udusb to give it that power.

Hello, I was being a Prncess and the pea with my fight stick, because I right-handed a PS2 Street Fighter anniversary stick, a right-stick player’s best off-the-shelf friend. The problem is the wires wouldn’t come out so i physically removed the acuators and crossed them up. It left a canopy underneath the joystick. I noticed some misfires so thought the wires were causing problems. I bought a new stick,and a bunch of extension wires. I decided to d the least drastic thing first, the wires, but the wires wouldn’t come out easily. I didn’t know whether to dire someone to unplug them or leave it. The price was WAY too expensive for labor. So I thought: I got a joystick, the must surely be some way to test heather the faults were with me or my stick.

In the meantime I took back the joystick and got the Undamned DB15 as an exchange. I tough it would wire all y buttons, apparently it only does 12 binary inputs, a ground, and a voltage. I wanted it for 8-button games like Injsutice 2, so i am currently taking THAT back, and as undamned creotr suggested, get a terminal block version.

The reason why I got an Undamned was twofold. Originally, I wanted to wire a fight stick to over 20 different consoles in a one-wire-one-funciotn manner. With the SF15AS and adapters I found I could play quite a few games right handed. But I need the undamned.to do two things. One is have a button swapping “telephone operator” board with ether 3.5 mm connectors or RCA connectors.so I can sea buttons without using any tools. Then I just have someone pad hack a PS2 controller to wire the stick, and then add adapters as needed. The other reason I need it is for the few controllers they just don’t make adapters for: The Atari jaguar, the Atari 5200, The Colecoviison standard controller and Super Action Controller, (there are games that only work with one and ones wit the other only), Intellivision which has been Flashback modded to hok up better controls, and a Bally Astrocade, and if there are known incompatibilities with the 3D Zero SNES controller adapter for 3DO, a 3DO pad with daisy chain. (Tototek sells one, but there’s no Daisy Chain)

So now I’m wondering does my joystick work? So i tried a character with difficult moves, Ken. That Dragon Punch is tough with a pad, and the few times you pull it off, it’s telegraphed> So after about a mite of warm ups, I was able to pull off 10 dragon punches in a row. Later I tried more stressful situations like from aback jump, from a forward jump, from a back run/high block, from a low block, i was able to pull offf 5 in a row of each.

So the final test. I played USF2NC against the computer as Ken. On skill level 4, I beat the game in one credit, with 5 perfect rounds including a double perfect and a perfect against Boxer (We know Balrog (US) was really M Bison (JP) before either Mike Tyson’s or Nintendo’s lawyers got involved. Just trying to be international. What names were used in other parts of the world?)

Not bad for a joystick test on a joystick that might have wires within the joystick mechanism. I’m pretty sure the joystick won’t fail me. Even though now I have a bigger percentage of Dragon Punches pulled than Fireballs and Hurricane Kicks. Time to work on Quarter Circles.

I talked to Undamned (after a couple weeks), use a 5v power supply to the board for ps2 and make sure ground from power supply goes to both the mc cthulhu and decoder board.
