Okay so, I am wanting to mod Forza Horizon online. Forza Horizon's title updates removes all the abilities to mod the game online. In order to be able to mod the game you will first need extract the title updates contents then patch the title updates contents using XEXTool.

After extracting the title updates contents you get the following xexp's:

default.xexp
SpeechFacade_default.xexp
XMediaFacade_default.xexp
media.zip

Apparently you have to patch the xexp's to the original xex's using XEXTool:

default.xex
SpeechFacade_default.xex
XMediaFacade_default.xex

The thing is I don't know the correct patch file names to patch these files. If anyone has any experiences with using XEXTool, please reply as it would be very helpful to me. Thank you
