Axun Workshop - Supergun-MINI

was able to find this on the official website, looks like supergun does the conversion

they put a sticker on top of the power supply, here is the original one: Unless they modified the insides of the power supply which I doubt considering the note on their website.

I know. I have an original as well. I use it for CPS2 with minigun supergun.

Logically, there is no reason to put that sticker there and assign -5v in the diagram to that pin unless it has been modified.

I tested that power supply when I repurposed it (because I did not find it adequate for my use case) and it outputs -5v.
 
good stuff, do you have the pinout for the cables by any chance, I have the same powersupply and I stripped the cables and will wire it for HAS.
Edit: Here it is :

WhiteGND
Green-5V
Blue+5V
Red+12V

I did not write it down and they are all under heat shrink now.

It should be easy enough to test with a volt meter.
 
Hello Axunworks!! I've got a supergun mini and have been using it with my IGS PGM carts with great success when running the signal through my OSSC->flat panel displays.
I also have a sony d14 BVM, and unfortunately I've run into seemingly unsolvable issues getting the output of the IGS+mini supergun to sync to the D14- I'm getting basically the same issues that are discussed in this thread about the newer HAS supergun- would the Axunworks mini have the same sort of circuit as the newer HAS that had this issue? My symptoms are exactly the same as what's discussed in that thread. I've tried running the signal through 2 different sync stripper/regenerators (gscartsw switch, and an extron 203) and neither has made any difference- no matter what on the sony I get a rolling screen unless I hit the horizontal delay button, and even then there's crazy extreme curling on the left and everything distorted.
anyway, wondering if there's anything I can try to tweak on the supergun to help, or if a specific sync stripper/regenerator might help.
here's the thread outlining the issues with the sonyd14 that i am seeing as well:
https://www.arcade-projects.com/threads/bvm-d14h5u-with-has-v4-2-with-cps2-or-3.28823/
And here's a youtube video showing the sync issues on my sony- the panasonic next to it in the video is getting the signal from passthough on the sony . . . panasonic seems to be fine with it :)

waveform of the sync being output by the supergun- any advice?

Is that output over VGA or Scart on the supergun cause that's TTL sync which you should be kinda careful what you connect it to.
It's expected over VGA but connecting that to hardware expecting lower level sync can be bad times.
Other than that looks fine.

Edit: Looks like it has VGA out, supergun output looks fine then.

yep I know it's ttl, I'm using cables with resistors for scart nothing's gotten fried!
check the thread I linked, I'm trying to get this to work with a Sony D14 BVM- it syncs with every other display I've used but the sony refuses. that model BVM is very picky about sync signals so I'm trying to see if there's anything I can do to get this to work with it even though that may not be possible. One recent thread with a similar issue (link is in post #88 in this thread) found some success with using an earlier revision of the HAS supergun- the later version would not sync when outputting the IGS, the earlier supergun would. So it seems like there's some chance of tweaking something at the supergun level to help this . . .

HI. You can try installing a BNC cap with a 75 ohm resistor on the BVM sync output. I see your BVM also has a SCART input, is it the same situation?
 
yep, it does the same with BNC or scart input. I do have the sync output terminated with a resistor already, no difference. I'm pretty sure the sony just doesn't like anything where the sync signal polarity is negative. I do have a sync strike that just arrived, I'm going to give that a try and see if it makes any difference . . . . but for now I'm just running the supergun into my retrotink 4k and using it with my OLED instead of the CRT.

Many arcade games have non-standard synchronization signals. Have you tried SNK-MVS and encountered the same issue? I've found it to be very stable on most PVM CRTs, so BVM might be more sensitive to synchronization signals.
 
Yeah just to necro this and close the loop- I could not find any way to manipulate the sync to get the d14 to work- tried a sync strike at the end even that didn’t do it.
Solved by picking up a Sony 20f1u, everything the d14 refused to work with is fine on the 20.
Maybe not the most practical way to solve this problem but it works for me 🤣🤘
Supergun still going strong, thanks for all the advice
