Hello,
I've bought a NEOGEO M1C Motherboard from a US seller and a minisupergun (rgb) from a french seller.

My problem is with RGB colours that are wrong, too bright and saturated, white colour is pinky, letters with green halo...

Can someone help me? My TV is a Sony KV-29LS35E. It works good with my Xbox360 in rgb and 60 hertz. Rgb cable is plugged in AV1 plug.

Thank You,
Ale

Superguns are supposed to have potentiometers to adjust (attenuate) the RGB levels (and possibly also the volume) since arcade boards have higher video output voltage levels than consoles/TV stuff. Here's for instance one I've built myself:

Bottom line: blame the maker of that supergun, i.e. someone with little knowledge and that rigged up a cheap contraption made with cheap parts and put it on ebay for a quick buck.

Even the cheap-ass minature MAK (Multi Arcade Konsole) Supergun has built-in adjustable pots for the RGB lines -- not a bad price for $150.00 USD. You do get what you pay for though. ^_~

Thank You for reply guys.
Today I tried my supergun with a CRT (flat screen) Samsung and everything goes well.
The only think is that graphics are too blocky (too aliasing). it looks like a C64 game...
Do You think that is for the bad quality of my Supergun?
Take r,
