Metal Slug 3 and Garou bootup problems with MV1 & Unibios 2.1

billd420 · Feb 14, 2006

For some reason my Metal Slug 3 and Garou carts have trouble booting like 75% of the time. When I boot them up, it goes straight into the cross hatch test as if there were no game inserted. I cleaned all of the contacts and both of these games are definately originals. Any ideas on what could cause this? Will upgrading to a newer mother board help? Its very odd, SSVS runs perfect every time on my current setup and it is even newer than Garou and Slug 3.

Very strange.....all I can think of is that your motherboard doesnt seem to like the early encrypted carts for some reason. Tried it with the standard bios?

Wierd... no problems with MOTW on my MV-1... it even plays SVC fine (post Unibios 2.2 install).

This isnt a unibios problem. Its certinally in relation to your mobo and carts. SSVS dosent have the same protection but MOTW & MS3 do providing its the original versions. Basically we are talking about the games with the SMA protection. Personally I think its a cart contact or voltage issue.

Its probably just the cart contacts then. Once the games get going, they run perfect for long durations. I'll clean the contacts tonight with a pencil eraser/ rubbing alcohol and see how that goes.

No problems with my MV1 playing my us Garou with a standard bios.

I can't have Metal Slug 3 and Garou carts together in my Big Red 4 slot Mobo .
(standard US Bios)
I have to remove one or the other..then either will work
The sound on the board will go out..

Perhaps its a voltage issue then. Maybe your powerpack isnt giving the MV-1 enough juice.

Teh B0ardz do vary quite a bit as to what they actually require at the +5v rail.

My 6-slot needs at least 5.2v to boot and run in a stable manner, whereas my MV-1F only needs 4.5v

Raz- I'm using a Jameco SC200 so I'm pretty sure the voltage is correct.

I'm also pretty sure that the issues I was having were with dirty contacts. I cleaned them very well with alcohol and cuetips and they have been booting a lot better than before.

thanks for the help guys,
Bill
