ARMSX3

Uses the latest RPCS3 upstream code (the recent ARM64 improvements included).

Building

arm64-v8a and armv8.2 is supported. You need the Android SDK with NDK r27 or newer, CMake 3.30 or newer, and a JDK 17. Android Studio ships all of these.

Clone with submodules, then fetch the two third party checkouts that are not submodules:

git clone --recursive https://github.com/ARMSX2/ARMSX3.git
cd ARMSX3
git clone https://github.com/SnowflakePowered/librashader 3rdparty/librashader
git clone https://github.com/bylaws/libadrenotools android/armsx3-ui/app/src/main/cpp/libadrenotools

Build the core. This is the long part and produces an unstripped library of around 1.3 GB:

export ANDROID_HOME=$HOME/Library/Android/sdk
cmake -B build-android -G Ninja \
  -DCMAKE_TOOLCHAIN_FILE=$ANDROID_HOME/ndk/<version>/build/cmake/android.toolchain.cmake \
  -DANDROID_ABI=arm64-v8a -DANDROID_PLATFORM=android-31 \
  -DCMAKE_BUILD_TYPE=RelWithDebInfo
cmake --build build-android --target rpcsx-android -j8

Strip it and put it where the app expects it:

llvm-strip --strip-unneeded build-android/android/libarmsx3-core.so
cp build-android/android/libarmsx3-core.so \
   android/armsx3-ui/app/src/main/jniLibs/arm64-v8a/

Then build the app:

cd android/armsx3-ui
export JAVA_HOME="/Applications/Android Studio.app/Contents/jbr/Contents/Home"
./gradlew :app:assembleRelease

The apk lands in app/build/outputs/apk/release/.

Note that the core library has to be rebuilt and copied again whenever anything under rpcs3/ or android/src/ changes. Gradle does not build it for you.

The Discord Social SDK is proprietary and is not redistributed here. Get it from Discord's developer portal and drop it in app/libs/ and app/src/main/cpp/discord_sdk/ if you want that feature. The build skips it otherwise.

Running it needs PS3 firmware, which is not included. License
