Bug in Factorio game with PS1 controller

[Brannon]

Hello, I'm testing a slightly unusual configuration on Factorio: I'm trying to play with an old original PS1 controller (the first one, without analog sticks) via a USB adapter. Since it's basically vintage gear from around the PlayStation 1 release date in late 1994, the compatibility is a mess. The problem is that the game detects the controller fine, but I have a major mapping bug on the movement axes that makes automation almost impossible. I searched the Technical Help section of the forum but couldn't find anything about this specific hardware. Has anyone else tried this kind of retro madness and knows how to configure it properly in the controls menu?
