What's new
I would try clearing backup ram and see if that makes any difference.
 
Yes, I have KOF2002, Neo Turf Masters, World Heroes 2, and a couple of others. I have tested all of them and they all work fine.
You mean that it boots fine on MV1C?
So it's a proof that the PCB is 100%.

I left the mvs-1c powered on without a cart for awhile and this is what it started doing.

After rebooting it again, it gave me this garbage screen each time I rebooted it. Strange.

I cleared the backup ram just now and still nothing. The Garou original cart doesn't want to fully boot.
 
Yeah all of the listed other games work fully on the mvss-1c ONLY the garou doesn't.
You are working with a 22 years old PCB, you know how many carts was inserted and removed from the socket? Of course will be some kind of contact issue.

About the actual error, still happening?

I booted the board this morning and everything worked fine. I booted it without a cart and it went to the I/O menu and I cleared the RAM memory again. It appears to be fine, again, no luck with Garou. I did a continuity test on the cart slot to the underside where the pins were at and everything checked out.
