A "cracked" is applied to proggy not content data. That is, you don't touch any content files including .fbl, .poi, etc...
It's the proggy that run a license check on the content you are using (what's under the content directories) If there is valid license for that content or proggy is fully cracked (no license needed) then the content will be valid (shown under Settings->About-Content->Map, etc...)
Note currently there is no fully cracked NextGen for WinCE. So if you have to use WinCE, stick to iGO/Primo. There are many versions of fully cracked NextGen for android.
