Which systems should I be bypassing the sync cleaner on, if any? There was a post earlier in the thread stating that a csync+this chip=problems. My next test will be to try to run the Saturn in without the sync cleaner, as a ghetto test to see if the sync cleaner is doing anything. Anyone have a suggestion of something that I could try with these silly wires? But cut up into what looks like quarters or something, flashing on screen, jumping around - total mess. Genesis + 32X - 'signal' with proper colors. Genesis, Model 1, DRM chip / high def graphics version - no signal.ģ. In the mean time, I'm trying to use bare wire leads to test functionality.Ģ. SCART headers weren't exactly easy to find, so while I ordered one, it's yet to arrive from the UK (it's been weeks). I am able to get a fantastic picture from my Saturn. (I've got some pictures but you can't really see the circuit, I'll get on that and post again) I used a non-tinned prototyping board to set this up, so you won't see cut traces.

I can certainly follow a schematic, and while my soldering skills kinda suck, they get me by. I think the circuit is working, but perhaps I've done nothing, lol. I figured it was an affordable way to check things out - if I throw my money away, at least it's not a ton of money. I am hoping there are still some folks in this forum that are willing to discuss. This is an older subject, but I just took on this project, exactly as outlined in the lead post. Rest assured that the Circuit works but your implementation has some issues - let's try to be objective and constructive, shall we? _

I am doubting that you have much in the way of test-equipment but there are a few rules worth following wrt to limiting noise and ensuring that you have good connections. Why not look back at the connections and we'll go through your circuit connection at a time? The Circuit does work and tbh it is not an overly difficult Circuit. I'm more than a month and I'm trying to solve the problem I did not find a solution, even in a lot of sites. So this problem never solved and my advice don't buy this shit.

i added LM1881 to GBS8220 with RGBS mod the screen flicking at 60hz and jumping at 50hz the, and about PSX & PS2 no signal and at RGBVH mod the screen not jumping or flicking but the signal wake and color like shit GBS8220 like shit too
