Hi

Time ago i bought this game, but my bios was E so the main board says not compatibility, but today i put the H bios and all games plays except this one, the test menu says its zero gunner 2 and can play test rom board, but i cant enter to menú or star the initial, after Naomi name, the monitor its black.

Thanks

Isn't H multi region? You set it with the dips. Are you just encountering a region lock perhaps?
