Hi everyone, I have an MV1FZS board that shows graphic glitches and vertical lines. I tested the board with the diagnostic BIOS v0.19a02, and it passes all the tests. The artifacts are visible only when running games.
Could it be related to the L0 ROM or the LSPC2-A2? I’ve used a logic probe to check the address bus and data bus signals on the L0 ROM, and they seem fine. No signals are missing. Power supply is ok, cart connector is clean.
I have other working boards for references. What should I check? Thanks
