Rotate with a button...

[ajlino]

I built a cocktail table with 2 sets of controls across from each other.

I can duplicate/split and rotate with a shader for head to head 2 player games. I put a "head to head" button on the machine, which toggles the cocktail shader between default and split/rotated. The button is a hotkey/m combo which rolls through the shaders. I deleted all but the 2 I want to use.

I need another shader which only rotates the screen 180 degrees. without duplicating or splitting the screen. Is there one out there? Or is there another way to manually rotate the screen during gameplay?

I need this because I just cant figure out how to get my roms to dependably work in cocktail mode. I've set the dip switch and saved it as an override. I assume classics like pac man and donkey kong should have cocktail rotation-ability, but I am getting no love from my machine.

Thanks. I'm pulling my hair out.

Hey there @ajlino ,

I am in the same boat as you with this issue. I have a 2 player cocktail table built running Retropie on a Rasp Pi 3.

I understand that not many roms support cocktail mode where the screen flips for P2, but I was hoping at least games like Pacman, DK, Galaga would work since the versions of roms I have appear to support this. But for the life of me I cannot get this screen flip to work at all on any game. I did manage to get Galaga to flip for P2 but it was all messed up and not playable.

Did you ever have any success on getting this screen flip in 2p mode to work? It's frustrating seeing videos online of people getting this to work with no issue at all, and I am following the same exact method.
