I'm having a serious problem with this. The buttons on my PS5 controller are just wrong.

Square is A (should be X), X is B (should be Circle), Option doesn't work, etc. And there's no way to remap them.

Is there a solution somewhere?

None as you've found out in the Wizardry proving grounds of the mad overlord thread.

Also the game crashes if I have my wired 360 controller plugged in. I have to wait for the press enter screen to appear before plugging it in works fine after that.
