I'm using a patched iso and my wiiu nand to play Mario Kart Wii on Dolphin. So far I've only been able to get it to work with Vulkan, and works only about 1/10 attempts. When using Vulkan I experience constant stutters which are not present when using the other backends. If I'm not using Vulkan I always get error code 20100. Tried redumping nand and repatching the iso but nothing has worked so far.
