So many different patches, wtf?
You only need the camera patch to fix the camera settings (camera is red). All other patches are optional.

Is the ROM rooted?
No and Yes. You should know some banking apps are not working anymore if you choose the rooted ROM!

What about other languages?
You can choose a language after install as usual

Are the GAPPS already installed in this ROM?
In default the Pico-GAPPS are built in. You dont need to install it again if you need only the play store.
You can choose another version of gapps. only change the file in: META-INF\gapps\gapps.zip
