I did go to Main Menu > Settings > Directory and check that my BIOS folder was set to home\pi\RetroPie\BIOS, but in that folder nothing showed up except its subfolders. How to replicate the problem: Just launch any Atari 5200 I don't see an Emulator Configuration option in the RetroArch menu. USB Devices connected: 2 Retro-bit Sega Saturn Control Pads, 1 Raspberry Pi Official USB Keyboard Power Supply used: Official 5V 2.5A Power Supplyīuilt From: Pre made SD Image on RetroPie website (retropie-4.5.1-rpi2_rpi3.img) Pi Model or other hardware: Raspberry Pi 3 Model B+ As far as I know, I've followed every instruction to a T, multiple times, in multiple different ways, and I've still gotten the same result every time. I even created that weird config file that the wiki said to make. I switched out all 5 BIOSes from at least 3 different sources. And it just boots into the same error screen every time (pictured below). I got my ROM library in \\retropie\roms\atari5200.
