Well i edited post because i found the specific problem, unibios It has nothing to do with it, the problem its with stock bios too.

The problem is on a MV1FZ board, games works fine witout graphic glitches, i test a lot of games 100 to 700meg and fine.
Problem appears on Service mode of the board:

Both of those sound like your board just isn’t properly displaying the FIX layer. The “Neogeo” on boot is drawn by the CROM data but everything else is FIX aka S1 iirc.

That only happen with unibios and specific games.

If it only happens on some games then it’s either the games themselves or a dirty cart or dirty slot.

Well I have been able to do detailed tests, indeed the problems are only present in one MV1FZ i have, but it is curious the games work perfectly without sound or graphics errors, but when I enter the service mvs and i go to setting up the game's soft dip the configuration letters ( only there) are glitched, also some specific games (kof 2003) do not allow me to see the service mvs mode (black screen) and the boot screen of unibios is partially displayed.

all of those games works perfect in other boards and no have these problems, what can happen?.

What happens when you swap the standard BIOS back into the glitchy board/cart combo? Do the problems go away?

If it's just in the service menu, check the SFIX rom.
