This is a modified version of the Dolphin GameCube and Wii emulator, based on version 5.0-8710 from 2018, patched specifically to run the Metroid Prime 3 Prototype on an Android phone. The Metroid Prime 3 Prototype is a TDEV (Test Development) debug build that requires more memory than a standard Wii game, and this custom build adds the patches needed to accommodate that on modern Android hardware. The author describes themselves as an IT professional with very limited C++ experience who used Google Gemini to navigate and debug the legacy codebase. The goal was personal: to play the prototype on a specific Android handheld device. The README gives credit to a Dolphin forum post for explaining one of the key memory patches. Two specific changes were made to the emulator. The first raises the emulated RAM ceiling from the normal Wii amount to 48 MB to match the prototype's debug memory allocations. The second hard-codes two memory controller flags to bypass conflicts that arise on modern Android processors when running old Dolphin code. Building the project requires three older, specific tool versions that must be tracked down manually: Java 8, CMake 3.10.2, and Android NDK r17c, which is a 2018-era release of Google's native development kit. The build runs from the Android source folder using Gradle. Installing the resulting APK on a current Android device requires the Android Debug Bridge command-line tool with a flag that bypasses the system's block on apps targeting old API levels. Modern Android will refuse the install without this override because the APK targets API 21, which is well below what current security policies allow without an explicit bypass.
