Thank you so much for your reply, but I can't get the GUI to work correctly. When I try to select "Import .O"
and then browse for the file, the possible formats available do not include ".o" file types. I don't know if this is a possible bug or not?

Did anyone manage to extract any models/textures from Fifa Street? I've been trying but not had much luck unfortunately.

I have downloaded Otools but I can't see an .exe to run the GUI, how do I run it? If someone could help me? Thanks in advance.
