I've extracted both roms to compare the files included in each and since i don't have a lot of time i thought i could share it in case someone wants to use it, to try and make the fmradio, gallery, camera or other motorola things work on GPE rom for example, or for whatever reason.
The zip i've uploaded contains the system folder of a normal rom, but includes only the files missing in the GPE rom included in the stock rom, so if a folder is empty it's because both stock and GPE contain the same files in that folder (or files with the same name, as some files are named the same on the stock rom but have been modified).
I know the gpe rom already includes the clock, hangouts and keyboard apps too, but they're not only named different, but the motorola apps actually take up less space so i thought i could just include them in case someone wants to use them too.
If you think i should add something more to this post feel free to comment, i'll try to keep the thread updated with useful stuff found out from this.
If you find out something useful, like the files needed to get something to work, it'd be appreciated if you could comment, not only to keep the thread updated but to learn about it. Thanks!
BTW if someone comes up with a better name for the thread please do tell, i'm horrible at naming threads haha
