The tutorials on jamma-nation-x under MVS should help. Also, there is an older, more general article from ben heck that should also help. And there is an old thread on assembler games that explains how to properly attenuate your video signals, there is a thread about using a pc engine amp that should also work.

Essentially the steps would be

1)The 5 volts only mod

2) Stereo Audio Mod

3) attenuate your RGB and sync signals to safe levels

4) (Optional) Unibios mod

5) Composite and S-video (Optional, only needed if you plan on using anything other than rgb scart)

6) (Optional) Battery Mod

7) (Optional, not recommended if you are really unsure of what you are doing) DFO Mod

8) Building an enclosure and wiring everything up with appropriate pinouts.

thank you for your support, there are someone who sell the premade boards? i am thinking that ordering the single parts it is too expensive. Ma sei italiano pure tu?

@Neo Alec are you running the RGB into something like an ossc, or do you have an RGB monitor? I have been thinking about consolizing a board as well and have been looking at the diffrent video options.

I am doing that and everything in between. That's why an RGB connection is versatile. I am currently spoiled and have both the Framemeister and an OSSC. I have a CRT TV modded for RGB. You can use an RGB monitor or an RGB to component converter. And not having the encoder built into the console or supergun means I can use the same connections for all my consoles.

Now that my m1vb is working well i was thinking to consolize it because on supergun it suffer by overscan iusse (image shifted to left) but only when i connect it to plasma tv. I was wondering if i can use genesis 2 cable that has already 75 ohm on the rgb lines and 1k on the sync line and buy only genesys a/v port. what do you think?

That should be fine. You will probably need additional resistors in the console to get the signals to the right levels.
