Upgrading my Mame cabinet with the latest releases (I'm a couple years behind). All fresh new Romset, everything configured and working BUT 0.284 gives me a driver error message for karnovr.cpp when opening neogeo games. Something about non-sequential bios. This message does not appear when launching from the OG Mame exe. Any ideas?
Edit: For whatever reason, if I launch through a front end this message doesn't appear. So for my use this is not a deal breaker. Still seems to work just fine.
