You still need this? It took me a while but I did build it using the instructions below

(Windows) git clone https://github.com/ppy/osu cd osu dotnet workload install android maui-android dotnet publish -c Debug --runtime linux-arm64 (or Release) (Saved location)\osu\osu.Desktop\bin\Release\net6.0 Copy over linux-arm64 folder to the pi (Raspberry Pi) sudo apt install 7zip sudo apt install libsdl2-dev https://www.un4seen.com/download.php?bass24-linux go into \bass24-linux.zip\libs\aarch64 and copy the libbass.so to /usr/lib https://www.un4seen.com/download.php?z/0/bass_fx24-linux go into bass_fx24-linux.zip\libs\aarch64 and copy the libbass_fx.so to /usr/lib https://www.un4seen.com/download.php?bassmix24-linux go into bassmix24-linux.zip\libs\aarch64 and copy the libbassmix.so to /usr/lib /home/pi git clone --recursive https://github.com/veldrid/veldrid-spirv/ cd ext ./sync-shaderc.sh mv src shaderc cd .. ./build-native.sh -release linux-x64 cd build/Release/linux-x64 mv libveldrid-spirv.so liblibveldrid-spirv sudo cp liblibveldrid-spirv /lib/aarch64-linux-gnu /home/pi mkdir libs cd libs wget https://chromium.googlesource.com/android_tools/+archive/20ee6d20/ndk/platforms/android-21/arch-arm64/usr/lib.tar.gz 7z x lib.tar.gz 7z x lib.tar sudo cp libandroid.so /lib/aarch64-linux-gnu sudo cp libdl.so /lib/aarch64-linux-gnu/ sudo cp liblog.so /lib/aarch64-linux-gnu/ sudo apt-get install libstb-dev add kernel=kernel8.img to /boot/firmware/config.txt sudo reboot cd (wherever you have osu) chmod +x osu\! LIBGL_ALWAYS_SOFTWARE=true ./osu\! stop the game from loading after the fonts load (ctrl + c) nano ~/.local/share/osu-development/framework.ini change "WindowedSize" to 640x480 chnage "FrameSync" to Unlimited change "WindowMode" to Windowed save the file LIBGL_ALWAYS_SOFTWARE=true ./osu\! osu should load in at 640x480 windowed
