Esprade slightly wonky picture

[Jonst]

Apologies if this has been covered elsewhere,I have just got a new esprade board (Japanese version),it works fine but I have noticed that the picture is ever so slightly wonky.its not a huge problem,I was just wondering if this is a tv display thing and is it a case of messing about with the service menu? Like I say it's very slight but it might bug me in time.this is also the same on my dangun feveron board.is this because they are ntsc?

Is this on a supergun or a cabinet? If the former, that's probably the reason.

Supergun...I have two,its the same on both but I havn't noticed it on any other games.

You should try out a JROK sync cleaner. It fixed the wonkiness and color weirdness on my early Cave boards and PGM.

Thanks! How do they work exactly? I really don't know anything about my arcade hardware/boards!

They're pretty simple and cheap. It's a tiny board with 4 wires coming out of it. One goes to +5V on your power supply. One goes into your video ground wire. One goes into your video sync on your jamma harness and one goes to your video sync on your rgb converter board. So it's basically acting as a buffer for the sync before it reaches your rgb converter. I just run the +5V one straight to the power supply and cut/strip/solder/electrical taped the other 3.

He won't be using a RGB converter, he lives in a country with real connection types - RGB SCART

I suspect this is the same crap I have to put up with when using Taito boards on my NNC, the screen just doesn't quite like certain sync signals.
