Tested on real sega 32x + a va1 genesis combo - and mister fpga 32x core ( latest release ) no NAMCO logo, all blank screen, tested other games (bad connection or other region issues etc , and worked perfect) maybe a header problem?? tested forcing all regions in megaeverdrive pro all 3 on the menu settings- but no luck. Any other suggestion? Thanks for your work, best wishes.!!!
