The slider was missing from the in-game menu entirely -- it only existed in the settings screen. That is the wrong way round: the quick menu is where the upscaler gets changed mid-game, and having to leave the game to tune what you just switched to defeats the point of it being there. Shown only for FSR and SGSR, since nearest and bilinear have nothing to sharpen. The label follows the selection in both places, because the number does not mean the same thing to each: it is an RCAS stop to FSR and an edge factor to SGSR, and a slider named for the upscaler that is not running is simply wrong. One control rather than two, deliberately -- both upscalers want the same thing from the user, and a second slider only lets them disagree.
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
