That's my signature. It's on all my posts. You should watch when you have time. Those videos take a lot of work.

Check the voltage off the PSU and on the Jamma edge with a multimeter.

i have 2 psu, ive tried both in my arcadeforge super gun, one provides 4.85v, the other 5.05v, theres a little voltage display. same issue with both of them, graphics jumpy and sound seems to go off sometimes around the screen jumping.

thanks
