Reicast Core Naomi Vertical Games, can they be changed to Horizontal?

Is there a way to play these games horizontally? If I go into the service menu and change the System Assignments -> Monitor Type to Horizontal, then I get an error “Caution 54 - Game Assignments are incorrect”. any way around this? Is there a way to set a retroarch cfg file per game to change the view to horizontal, or is there a core option that I’m missing? Any help would be appreciated.

The games were built to be vertical, the closest to horizontal you’re going to get is that top screenshot there where everything is on it’s side.

Ideally with these kinds of games you’d set the screen rotation to 90 degrees counter-clockwise. Or just put your monitor on it’s side lol.
