[Solved] lr-duckstation blank screen (BIOS issue?)

[ChaosEffect]

Pi Model or other hardware: Pi 3B
Power Supply used: CanaKit 2.5A
RetroPie Version Used: 4.7.1
Built From: Pre-made SD Image on RetroPie website
USB Devices connected: Wireless keyboard/mouse combo, various controllers
Controller used: Hori Pokken Tournament Pro Pad, wired 8BitDo SN30 Pro, Logitech F310
Emulator: lr-duckstation

This emulator was just officially added to RetroPie a few hours ago as an experimental package with pre-compiled binary, so apologies if I'm jumping the gun here asking for support!

The libretro website indicates which BIOS should be used and how they should be named, but I only get the game sound to play (no picture) no matter which BIOS I try. There is just a black screen with the sound effects and music playing. I can still access the RetroArch menu fine and exit the emulator with Hotkey + X (EDIT: oops, meant Start).

Has anyone else experienced this issue?

The Pi3 doesn't have OpenGL support, so it duckstation fails with

[ERROR] Requesting OpenGL context, but RetroArch is compiled against OpenGLES. Cannot use HW context.
[ERROR] [Environ]: SET_HW_RENDER - Dynamic request HW context failed.
[INFO] [Environ]: SET_HW_RENDER, context type: gl.
[INFO] Requesting unknown context.

Try setting duckstation_GPU.Renderer = "Auto" in /opt/retropie/configs/all/retroarch-core-options.cfg and see if you get video. Otherwise you may try using Software instead of Auto.

@mitu "Auto" didn't work, but "Software" did. Thanks!
