Zero gunner 2 cart not working.

Postby maxio098ui » April 7th, 2011, 2:19 pm

Hi,

I got a naomi MB which is working, but the zero gunner 2 cart doesn't work at all. When I turn the system on the screen stays black no sound no nothing. is this a known problem or is this cart beyond dead?

Thx
The screws used to seal up this cart are wood screws. Nobody is going to waste good wood screws on a bootleg, they'd just use cheap electronic screws instead.

You have the usual make sure contacts are clean and cart properly seated. Other than that, have you opened it up to make sure everything looks OK?

- Did you try another cart?
- Is it seated well? My ZG2cart was very stiff to insert. (Shouldn't stay black tho, but give error 01 instead of black screen.)
- Is there sufficient power? (or too much maybe?)
- Is the fan on/spinning when turned on?
- Try swapping out another filterboard from another working Naomi.
- From whom/where did you get this ZG2 cart?

ZG2 runs on any bios afaik

Try plugging it in without its plastic case.

Sounds like a motherboard issue, you should still get the bios screen

yeah. sounds like a mobo issue. check voltages. if it was cart related you wouldn't get a black screen, rather one of the many error messages...

Try to do the rom test.
For sure you have some bad roms inside the cart, like mine.

I would try and check if bending the pins/connectors back might have broken a trace by accident, or loosen a broken trace under the connector which was already making contact by chance.
My 15kHz cabinet Peplos will never power up, with any item, and I am quite proud of that.
