So it apears I need to set my system to 223 to play Guitar Hero Backup dvd. It just black screens when I am using 249 and negogamma r9 beta 39 or something to that extent. I tried utilizing a wad to install 223 (which it seems to appear to be on the system already, cause my wad manager 1.4 I can switch ios from 249 to 223, or 222, etc) after installing it, I went to neogamma to load it but it says ios 249 is still loaded. Am I supposed to UNINSTALL 249? Any help would be appreciated. THANKS!
