You can mention how you did it, you can't pass a stadium or better what conditions does that stadium have so that the Xbox can take it or what version of FIFA is it?
Stadiums Information!
1. FIFA 14 PC is about 20-30 megabytes in size
example
(Old Trafford)
stadium_1.rx3 = model
stadium_1_1_textures.rx3 = day texture
stadium_1_3_textures.rx3 = night texture
2. FIFA12-13-14-15-16-17-18 version xbox360 are compatible to FIFA19 or FIFA19-20 seson mod ver.
3. but the basis for everything is that the game is fully unzipped with the big extension files.
4. I've written in the past that many things affect even the operation of stadiums, so many times texture bugs, or worse, fatal crash quits.
Images from Eibar and Alaves stadiums were from FIFA19xbox360.
But you can insert FIFA14 or FIFA15 or FIFA16 or FIFA 17 or FIFA18 and so on.
Plus Information:
There were no crowd in the stadium!
Because no crowd_1_1 or crowd_1_3.dat files were assigned to it.
It was only test-driven.
Unfortunately they are big in size and so the game freezes.
Yeah, I didn't even mention that if you want to put it in the game as a separate stadium instead of the Old Traffort, you have to put it in the database.
