echo "🎯 Emulator launched with Mesa software rendering!"
echo ""
echo "📋 Configuration:"
echo "  - Mesa software rendering"
echo "  - No hardware acceleration"
echo "  - Fast startup (no boot animation)"
echo "  - Clean state (no snapshot loading)"
echo "  - Bluetooth disabled (prevents hangs)"
echo ""
echo "⚠️  Performance Notes:"
echo "  - Slower than hardware acceleration"
echo "  - More CPU intensive"
echo "  - Use only for stability testing"
echo "  - Good for debugging GPU issues"
echo ""
echo "🔄 To return to hardware acceleration:"
echo "  - Use ./launch-emulator-gpu.sh for NVIDIA GPU"
echo "  - Use ./launch-emulator-opengl.sh for Pure OpenGL"
echo "  - Use ./launch-emulator-angle.sh for ANGLE mode"
