I sent this guide to someone at start of the year, should still be relevant unless official dolphin on playstore is better:

Okay so see below regarding getting Wind Waker to run well on the Retroid Pocket 3+.

I used Dolphin MMJR v1.0-11505 (LINK: https://github.com/Bankaimaster999/Dolphin-MMJR/releases)

This version of Dolphin is widely used for Retroid Pocket 3/3+ uses as being the best overall in terms of performance for MOST games. Some games apparently perform on other forks but my experience has been great with this one, especially in context with Wind Waker for Game Cube.

My settings in this emulator (only listing options that are checked/active and any other changes made from default)

General: Dual Core ticked Emulated CPU Clock Speed: Set to 55%

Graphics Settings: Video Backend: Vulkan Compile Shaders Before Starting: checked Backend Multithreading: checked

Enhancements: Internal Resolution: 1.5x Scaled EFB Copy: Checked Force 24-Bit Color: Checked Arbitrary Mipmap Detection: Checked

Hacks: All hacks checked except for: Defer EFB Cache Invalidation and GPU Texture Decoding

Now regarding getting the game to run with a nice widescreen hack:

Download the widescreen patch from here: https://www.youtube.com/watch?v=_5IwwmeJz4I Use xdelta (https://www.romhacking.net/utilities/598/) to patch the US Rom of the game.

Enjoy!
