I use 7zip to unpack and open ISO files. I use ImgBurn to make a new ISO from the files.

Hi!

I just made the same modification for Star Wars Battlefront 2 (NTSC-U version) and it works!

To proceed to the modification you must go to offset : 073A24410 with Hxd (an hexadecimal editor) :

At this offset you must modify the hexadecimal values

To this :

67 73 5F 6C 6F 67 69 6E
:



I tested and it works!

It should also works for Pal versions but the offset must be different.

Best regards

Breaking news!!!

I tested on Star Wars Battlefront 2 Pal version (SLES_535.01) with this modification and it's working!

The offset for this version is at : 02EBECA40. Just replace the Hex values :
