I believe Street Fighter II uses six buttons per player?
Any Supergun will have coin and start buttons, they don't count.

I don't know what you want a Supergun for if you're not going to use the controls on it anyway. Being focused on "a Supergun" you're only making this more difficult for yourself.

Those are Neo Geo AES game pad ports. My Neo Geo motherboard has those as well.
You can't use those for Street Fighter II anyway, they only have four buttons.

So you really don't need a Supergun.

With this thing you can hook up any 15Khz arcade PCB to your television:

If you live in Europe and your TV has SCART input, then you don't need to do any conversion, you can connect the PCB directly to your TV. Make sure the SCART input on your television supports RGB video.

Then you need
- a PSU for powering your Street Fighter II PCB and the video converter
- the pinout for a six-button Sega Genesis controller (should be easy to find)
- some wire, a soldering iron and some other tools
- a female JAMMA edge connector
- a Street Fighter II kick harness
- some kind of box to hold the power supply and the video converter
- two female DB9 connectors for connecting your Genesis controllers (*)

You can hook up the sound outputs from the JAMMA harness directly to your TV. Just be careful, arcade PCBs are much louder than standard line-level so make sure to set the volume on the PCB very low at first so you don't fry the TV's audio inputs.

Once you've learned how to solder and de-solder (practice on some trash circuit board) and you have the JAMMA + kick harness pinouts and the pinout for your Genesis controller it's really only a matter of connecting the dots. 12V out goes to 12V in, P1 up goes to P1 up etc.

EDIT

(*)Problem!

The six button Genesis controller is complicated:
http://pinouts.ru/Game/genesiscontroller_pinout.shtml

Buttons 2-6 share pins with other outputs so hooking it up to JAMMA straight through will only work for button 1. Button 1 connects to ground when pressed, but with the other five buttons you'll have to deal with +5V and a "select" pin..so you'd need some extra circuitry to interpret that before it goes to the JAMMA harness.

Edit

Yes, there's a thread about this here...unfortunately they don't discuss how to deal with all six buttons. It seems to be a lot of work just to get the first three buttons to work (see page four of the topic).
