I use a VGA upscaler like this here - http://www.neo-geo.com/forums/showt...ooking-up-MV-1-gt-CGA-to-VGA-converter-gt-CRT.

If the monitor can go down as low as 15.75 kHz, you dont need anything, just connect the red green and blue to the right pins, and then the sync to the H pin.

What power does the VGA converter require? What ever it asks for, is what you should feed it.
I would guess itll want either 5v DC, 9v DC, or 12v DC. If youre using an ATX power supply, you wont need to worry about the current requirements, the ATX should deliver more than enough.
You need to connect the RGB-S connections as well as the ground connection to the 15.75kHz input on the converter. How you do that is up to you, here is a pinout of the MVS edge connector: http://www.hardmvs.com/manuals/Jamma2NeoGeo4SlotPinout.pdf

Sorry about that, what i mean is using that pinout there in that link, you need to connect the 3 colours, and connect the sync and ground to where they go on the converter.
Someone else may be able to put it a better way for you, that is about the only way i can think to say it

so what I need to buy is this:

That converter needs 5v at 2amp. It comes with a cable you can use to make an adapter from your ATX PSU if you add a molex connector to it. It also comes with a video input cable that you could wire to the supergun (depending on what connectors your supergun has - has it got screw terminals for RGBS as well as an RGB scart socket?)

That's the real power requirements for both the upscaler and a mv1b: just 1.21 amps.
The cart on the pic is a bootleg with newer chips, so a legit cart with high meg count and old toshiba roms should waste more power.
Maybe the pic help you. I don't need a supergun since I use the jamma edge signals to feed the upscaler.

An ATX power supply should have no problems delivering this tiny amount of current.

The PSU I used on that basic scheme is this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280334885196
I don't understand well what you mean with "supergun". In that pic, I just soldered the wiring that comes with the upscaler to a jamma connector and the power supply, not to any supergun. In fact, doing that you're building an ugly supergun

.Just need to connect Sync and GND. If it's like my one, use the grey sync wire that is next to the RGB wires - connect it to Sync on the Jamma connector, ignore the yellow sync wire. connect the black Ground wire to any of the GND points on the Jamma connector.

Yes, it's normal the first time you turn it on.
Just let pressed the "auto" button for 5-10 seconds.
Oooh, I forgot about this. My MVS did this also, and I spent days on and off trying to sort it, until I remembered to hold the auto button for a few seconds to get it to adjust.
