Hi all
I have a MV2F that had issues with the backup ram and some other minor issues.
Fixed the backup ram (some traces of the HC32 were rotten, upper BRAM didn't have its WE connected, etc.).
Some NEO-G0 and NEO-257 were replaced (upper left area of the board, next to the battery), not all legs were soldered on on one and its obvious that someone desoldered some of them (slightly misaligned).
I've cleaned the cart slots, haven't adjusted pins yet as I don't think its necessary.
Now it works, diag BIOS is happy, however when I populate both slots, one with a 161 in 1, and the other one with Metal Slug 2, there is graphic glitches.
It doesn't matter what cart is in what slot.
My suspicion is that its something about the multicart causing this, but I don't have other MVS carts to test..
Any hints/suggestions?
Edit:
same when using UniBios 3.3 or stock BIOS
