Latest Gamecube Developments on Pi4

@george-spiggott Oh right, well thanks anyway. I was curious about this game as I was planning on playing through the Mario RPGs. Regardless your findings are very encouraging.

Anyone tried Alien Hominid? I heard it plays well on low end machines. I'll test it myself when I rebuild my 64bit build but it may be a while.

I am testing Mario Kart Double Dash with on RPi4 64 Bit and run into the following problems:

Graphics works fine when I choose player and kart.
When gameplay starts, I do not see the kart and track. Everything seems to completely dark, except for the overlays which show e.g. the name of race track or current race position.

Here is my setup:

RPi OS 64 Bit with kms enabled.
Dolphin 5.0-14017 compiled from source.
Mesa 21 including Vulkan compiled from source.
I do not have any serious overclocking applied (cpu_freq=1750, gpu_freq=600)

In Dolphin's graphics config, I choose OpenGL or Vulkan V3D 4.2. No matter what, the result described above stays the same.
Does anyone encounter similar results? Any hints?

Best,
gandalth

@gandalth23 Yes I encountered the same symptoms on both my Pi Dolphin builds. No idea what the cause is.

George, thanks for sharing!

Meanwhile I tested the same setting on 64-bit Intel Debian Buster and it works perfectly on that setup. I wonder if it's a bug in Dolphin.
As I'm new here: does anybody if there are any Dolphin developers following this forum?

Best,

You need to run a 64 Bit OS on the RPI4, e.g. this one:
https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2021-04-09/

On this operating system, you can pull the sources of Dolphin, and compile it. The sources and building instructions are here:
https://github.com/dolphin-emu/dolphin

This does require some work. If somebody is aware of an easier way, please chime in.
