What's new
Wanted some clarification on here..this process helped me get a signal on my Astro City..but it also requires a very limited GPU set up. Is the process the exact same if I got a New Net City and if not, how is it different? I would like to run a MAME/BigBox setup on NNC but fear some of the games I'd want installed (Naomi/Atomiswave, etc) might be too much for the GPU setup I have for the Astro. Thoughts!?
 
The "r9 380x" card is the last ati card made with groovymame compatible analog out over the dvi-i port. It's a few years old now but powerful enough to handle the 3d of demul/flycast/m2/supermodel/teknoparrot and many pc games.

Or use any modern card with the "njz3 videoamp" adapter.

And there's no issues getting that r9 setup working with the CRT in a NNC, Micky? My main concern was the CRTEmudriver thing with the wrong card and breaking something. Then I was thinking recently that I didn't know if they JVS nature of an NNC would factor into that process at all.
 
R9 380x works fine with emudriver.

It would depend what monitor you have in the cab. When you run vmmaker, choose your monitor model. It could be a trisync and if so that is the best monitor you could wish for with emulation as it will auto switch to the exact resolution of the game regardless if low mid or high res.
 
Regarding JPAC, I did some delving into why it's so oversaturated, and I found a solution. Or rather, Porkshop Express found the solution when I asked about it regarding the mistercade.


From my Astro Repair thread:

https://www.arcade-projects.com/threads/astro-city-restoration-and-monitor-fix.11781/

This is very interesting to me. I saw that thread with picture of the resistors in series, but is there a better picture of it how it's soldered? I would love to do this. I think the picture quality Is very impressive. Especially since I have a j-pac hooked up to an ms8.
 
I have a weird IPAC2 issue I cannot track down and looking for some help, on Big Box or Devilblade reboot games, i get constant scrolling or mouse input moving the mouse up left. Below is what I have checked so far and also talked to Andy, but we didn't figure anything out.

I have the IPAC2 in keyboard mode and if I open Notepad or anything just in windows I get no indication that any of the arrow keys are being pressed and can freely use the joystick to scroll normally. If I remove all inputs from my arcade cabinet to the IPAC2, it still continues. Keyboard Test showed no input, Eventghost showed no inputs. No errors showing on teh IPAC, on the lastest multimode firmware.

If I unplug the ipac2, the scrolling stops during the apps affected. If I change to DirectInput mode it stops as well.

No scrolling seems to occur on other list based things that scroll using arrow keys, such as steam library, webpages, etc. Only when I open certain full screen apps. BigBox and DevilBlade reboot, but not KOFXIII in FS mode.

I checked usb game controllers to see if I may also be getting a game controller input even though I am in KB mode, but see nothing listed there. BUT, I disabled controller support in Big Box and it no longer scrolls, so I feel it is something to do with a stick\pad command being sent since that is what controller support uses in bigbox.

I disabled xbox gamebar, steam input, bluetooth.

I hooked the ipac2 up to my laptop and launched devil blade and had no scrolling, so it must be something on my arcade pc that is interacting with the IPAC2.

Looking for something else to test or try to capture the input that is causing issue. The Arcade PC is running Windows 10 in test mode for Groovymame and CRT EMU drivers and basically a fully fresh install outside of some game programs, no joy to key software or similar installed.
