Swanstation Core not launching on Raspberry Pi 3 Model B+ Lakka 4.3

[retrogaming]

Hi, I recently installed Lakka 4.3 on a Raspberry Pi 3 Model B+.

I cannot get the Swanstation Core to load a game. I have all the BIOS files and they are recognised.

I am hoping someone may be able to help?

I enabled logging and saved the contents below; it looks like it is related to the GL driver?:

EDIT: I have an updated version of this core that fixes this and should also run faster. I can share it next week.

Swanstation need to use the Software renderer on the Pi3.

See this link for a workaround. Note that the setting string may have changed.

Lakka 3.4 Rpi3 aarch64 Duckstation won't start

It’s because it’s trying to use the OpenGL renderer and the RPi3 only supports the software renderer. SwanStation is patched for this in Lakka but DuckStation is not. Edit the DuckStation opt file manually so that it uses the software renderer: duckstation_GPU.Renderer = "Software" I should note that I have tried to use the DuckStation core on my RPi3 on RPi OS aarch64 and it does not work (not because of this, it segfaults), but it might work in Lakka.

That is awesome, thanks very much @metchebe

I overclocked Road Rash 3D to 200% and it runs really well.

(Edit: 200% caused CDDA errors, but it was still impressive either way)

I found the opt file here:

LAKKA_DISK/.config/retroarch/config/SwanStation/SwanStation.opt
