I have a Hangtime board… May I purchase ROMs from someone? I understand the risk of it being a test release

When I power the game off the JST-VL port, it will show that init screen. When powered off jamma, I never see that screen. While it may not be the answer, that that might help with troubleshooting.

I have a second rusty panel. (bought two ok baby cabs) I will try it out ty!

Use some real gloves when sanding away the rust on the panel. I got an acute infection near my fingernail after stubbornly sanding it down with my nitrile gloves. Long since recovered but still

Interference resolved!! Kept EMI filter in because why not. I didn’t ground every device but this time I tied the grounds with a very short but large gauge wire. Admittedly I was using a thin long wire as a quick test before. The idea to tie the grounds came from the Midway KI manuals. The...

EMI filter didn’t change anything. Next time I’m in there I’ll ground everything per that diagram. I also ordered another EMI filter.

Ordered an EMI filter 🫡 Thanks for the suggestion. It wouldn’t have crossed my mind.

The video wires I snipped off the original harness. All other wires I ran new. Maybe the video wires needs shielding? More pics: I recorded a video but YT made it a Short and compressed it. I’ll reshoot and reupload on desktop View: https://youtube.com/shorts/BozVzL4cRYk?si=fAqQzfWB2Wpod8Ys

I nearly finished with my ok baby so I’ll bite. I rewired the cab as well. Making the harnesses was super time consuming but it had to be done. I also replaced the chassis, PSU, and the iso transformer. I tried to reuse the existing iso but it made the picture look horrible. - Meanwell RT-65A -...

Correct, you need to power it via that port: https://wiki.arcadeotaku.com/w/JST_VL Pinout here: https://forums.arcade-museum.com/threads/sega-naomi-gd-rom-power.420947/#post-3744920 The 3.3v is not necessary; just the 5v and GND pins. If powered by that port it'll search for a JVS board on...

I'm surprised your LCD supports a low resolution. I've had the same interference issues if powering the game and the upscaler with the same power source. You have a similar situation. As you don't have an upscaler, I'm unsure of how to resolve.

How are you upscaling the video? It looks like an LCD

I have a Blue Alpha, and a Green Zero 2. Just need a working A board that supports them. I’m ok with a beat up one and/or one that needs infinitikey; I’m putting it in a new case + will replace the battery anyhow. I’m in NY, 11106
