Hi guys, so I tried connecting my JPac to my Sega Blast City a day ago, but when I turned on the machine all I got were some multi-colored vertical wavy lines. I turned off the cab immediately just in case the signal was bad for the monitor, so I don't have a picture. If it's not going to hurt the monitor at all I can try to set it up again and post a picture of the problem.
I'll give you my whole process so you can see if anything is wrong:
Place one jumper on the 31khz section.
Plug it into the Jamma harness.
Attach the JPac to a USB 3.0 port and to a VGA port on my motherboard because my graphics card doesn't have a VGA port. (Also, I enabled those ports in the bios, so that's not the problem. I do have a DVI to VGA adapter laying around that I can try if you think that plugging it into the graphics card could help)
Now, with a separate monitor, I set the resolution of the cabinet's monitor to 640x480 60 hz in the display adapter properties before turning it on. (Image of the option I chose shown here:
)
With the computer running and the second monitor still plugged in, I turned on the cabinet.
