Steps to play cs on android.
1. You must have a file manager to manage your files that you downloaded.
2. You then must download both the app and data from the links above.(sorry, i'm not so sure if they have this for ipods,iphones and such). (Just click on zip when downloading the data from gitbub)
3. After you dowload the required stuff, extract the data and make a new folder so that you can have easy access to it.
4. Go to the app and go to settings. Then go to path settings and set the path to the data you downloaded.( it should be called nx-engine-libretro-master. Another tip for this(just go to datafiles and you should see doukutsu.exe . If you do, set this as your pathway.
5. After you set the pathway, go back to the retro arch main menu and scroll down to doukutsu monogatari (nx-engine) and click on it. After that, click on doukutsu.exe.
And you're done!!! Rply if there is any issues. If anyone has a wiimote, you can play cs on your android with it.
