i finally found out problem while play clannad using rlvm with android. App won't be able to run if we use android 4.4 or 5.0, it will kick us back to main screen. But with a little trick, it still run fine.
We have to find a phone having android 4.3 or bellow and put microSD card(with clannad folder inside) on that phone. Install rlvm and run clannad for once. After that, put back microSD card on our phone. So our phone would be able to play it.
But i'm having another problem... That i can't save or load. Even if i copy save file from computer to card, i still unable to find any thing to load....
