What's causing these glitches?

As the title says... In the video below, the game was fine when it was first loaded up. I left it running for a while only to come back to this. The same happens when I power off for a while and restart, the game runs fine, as it should, but leave it running and it starts to glitch again.

Came across a few "Exception Error Handling" errors yesterday, also. Some graphical glitches in the top third of the screen on Fatal Fury 1, like small white lines running across.

Do I have a bad NeoSD or is it my MVS? The person I got the MVS from says it's the cart...

that problem is a faulty character board prom, any one of the prom have data missed

Anything? I'm trying to get this sorted as quick as I can so I can know if I can keep the MVS or send it back to the seller if it's not the NeoSD.

Can you check the voltage at the jamma edge? Also, which MVS model are you using?

[Relikk]

Sorry, should have mentioned that it's a consolized MVS. It's an MV1FZ.

Can you measure the voltage in the jamma 5v pins? I think it might be a bit low. Neosd needs slightly more power than an original cart.

Can you measure the voltage in the jamma 5v pins?

It's getting a consistent 5v (5.01v), it seems.

And this happened again while I let it run. I cleaned the cart and the cart slot a couple of days ago, but this still happens.

Thoughts?

It's weird. Can you do a quick test? go to options and enable arcade mode, load a game with issues, turn the mvs off and take the SD out of the neosd. If it doesn't show glitches, the we could try the firmware that fixes a similar issue in some MV-1 (older, very large) boards.

[Relikk]

Ok, tried all that. Still glitching.

Weird how it always starts out fine but give it 10 minutes and it starts glitching.

Well, we can try the firmware anyways, send us an email to support at terraoniondotcom with your neosd serial number so we can send you a firmware update to try to fix the issues.
