Screen flipping for 2P on Namco System 16 games?

[Well Fed Games]

Hey, so I'm almost done switching my sister's 60-in-1 over to MAME and have come up with a problem. Certain Namco games (Blast-Off, Blazer, Dangerous Seed, Dragon Spirit) flip the screen 180 degrees when it is 2p's turn.
Cannot for the life of me find a setting to change this (no labeled cocktail options are turned on) and can't imagine this is how the original cabs were. Anyone have any ideas or could check to see if these games do the same thing on your setup?

Play with each games dip switch settings.  E.g. on Blast off I set all of the dips ON and it doesn't flip the screen.

Ah, thank you. I was wondering if some of those unspecified dips were the issue. I will experiment!

Alright, I figured it out. Have to go into service settings (via dip switch menu) and set the cabinet type to C (upright). All my games had defaulted to A (table). This worked for Dangerous Seed and Dragon Spirit so I am assuming the other system 16 games are similar. Thank goodness for people who post arcade manual PDFs online.
