For me, it's a little difficult trying to get the .rx2 files to compress properly so it can be re imported, but what I have got is:
Custom center ice
Custom ice ads
Custom jerseys (kindve, I got vancouver's 2018 jerseys in, but when I tries to get Vegas in it imported everything but the actual image of the Jersey, so it has the normal and fonts)
Custom power ring
Custom goalie masks!
I need help to bring this to it's full potential. If anybody has an RGH/JTAG 360 and wants to help me exploit these files please feel free to reply to this!!
