The core is built for armv8.1-a and that is a floor, not a preference: util/simd.hpp emits SQRDMLAH and util/asm.hpp carries inline LSE atomics. On ARMv8.0 silicon -- Cortex-A53/A57/A73, so Exynos 9610, Snapdragon 660 and the like -- those are illegal opcodes. What the user saw was a bare crash. The fault is a SIGILL inside a static constructor while the linker is still running libarmsx3-core.so's initialisers, so it happens before any of our code can report anything, and the top frame names a log-channel registration rather than a CPU problem. Because the core is dlopen'd lazily, it surfaced at whatever first needed it -- issue #15 filed it as "crashes when selecting the firmware .pup file", which is where the crash appears and not what it is about. Check /proc/cpuinfo for atomics and asimdrdm before that dlopen and report it. Checked across every core listed, not just the first, since emulator threads are scheduled on all of them. Fails OPEN by design: an unreadable or unfamiliar /proc/cpuinfo returns null and loads as before. Blocking a device that would have worked is worse than the crash this replaces. Verified on a Snapdragon 8 Gen 2 that all eight cores report both flags, so nothing changes there. The reason is also held in unsupportedCpuMessage so a screen can show it later; a toast is easy to miss for something this final.
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
