When used with the SLG I would argue that this is then masked to a large degree.

Beaps,
It won't sort your problem, plus the HDBOX Pro is Component only.

PAL consoles cause all sorts of shit with this stuff. Either grab your nuts and get NTSC consoles or grab your nuts again and buy a proper processor. :wink:

Lot of grabbin my nuts going on here :shock: :lol: :shock:

Well I am sending back that that sync strike for a kick off. You sure that RGB SLG Scart scanline thing isnt up to the job?

Saying that my Saturn is Jappers & the pic is trerrible also

You're sending sync strike back despite the issue being PAL consoles?

I doubt it's sync strike really. I just got one of my sync thingies sent back, I couldn't replicate the issue. People need to realise it's most likely their hardware causing this. It's a nightmare selling this stuff, for everything that gets sent back we sellers have to increase prices to cover it. I just put up my prices on some of my stuff by $1 to cover all the returns I get.

The issue with your Saturn could even be your TV.

Sorry it's not a console problem I have.

So, did anyone wire up external buttons to their CGA2VGA? I've put mine inside my supergun now and I'd love to be able to wire the AUTO button at least to an external button in the gun's shell. Can I use the common ground and just solder a wire to the correct pin on the mini pushbutton soldered to the PCB or does it not use common ground?

Of course I've got one. :) I'll figure it out.

Meanwhile I'm very happy with the picture this thing outputs (the MVS mobo is standing on top of my supergun case, an old DVD-player):

Gonna hook the buttons on the front of the DVD up to the scaler's buttons.

Did some further testing today running this on my Plasma TV and some strange things happens... After a while the picture looks overly saturated and then get very dark (running a 1-slot NEO GEO) so I can barely make out highlights such as credits and LEVEL 4 at the bottom so I know the NEO-GEO's still running in the background. I'm powering the mobo + the scaler off a PicoPSU. The LED on the CGA2VGA flickers a bit when this happens, is my power not up to specs? I also have my SLG3000 hooked up.

The menu works fine even though the game's picture is almost invisible and if I change resolution the picture's back/OK again. Do I need to put resistors on my RGB lines? There are three pots on the CGA2VGA that I thought could change the input levels, but I never saw a difference while adjusting these.

Your power sounds not up to specs. The LED flickers when it's looking for sync, but this is a stable flashing. It sounds like the board is struggling.

The board needs a 2 amp 5V power supply.

Neo Geo shouldn't need anything on the RGB lines, and I never get any issues with Neo Geo users, it's compatible with basically anything. It does need tweaking on some revisions of the board to fix crappy RGB, but that is visual artifacts, not heard of it affecting output from VGA scalers like this.
