I have had the chip installed for the past 2months and working no problems with several games.
I have not tried to go online as of yet. I wanted to know if I can go online and download new content for Guitar Hero World Tour?
Has anyone had any luck? is it safe?
Yes. At this point you can go online and update with all types of chips. At this point the chips are pretty must stealth. They way they work is by detecting when a backup is inserted and patching the signal sent to the system so it appears as if it is an original disc. For this reason it is very difficult to detect the presence of the chips.
