On my Lenovo A399 phone  when I'm in a middle of a game or just load game and boot bios  it goes back to the reicast menu  and also in Sonic Adventure 2 on my Samsung Galaxy Tab 4  I cant get full screen to work and when you're trying to defeat king boom boo  his shadow is nowhere to be seen  but anyway its cool because this is the only Dreamcast emulator on android. Please Update and I'll add 5 stars.
