N-Gage (2.0) users
Unlike the N-Gage, N-Gage 2.0 is actually a game service, that is ran on a normal Nokia phones like N95, 5320 Express Music, N82, ... Those devices are powered by Symbian OS like the original N-Gage too, just that those phone use a much more morden version of the OS (S60v3 phones).
People are often confused on how to install this service, so there is too a page dedicated to N-Gage (2.0).
I'm an experienced Symbian users. But I still don't know what to do
EKA2L1 needs files from a real phone to emulate that phone's operating system and UI. So first of all, you need to install a device's files, or in EKA2L1, we call it install a device.
