I'm able to inject most of the games on my ps3 super slim (4.70 OFW), but some game like PES 2017, WWW 2k17 asking me to upgrade to OFW 4.75.
Could you please help me to fix this or i cant play these game on ps3 OFW 4.70.
this has been mentioned before, but just change the "PS3 System" entry in PARAM.SFO to be lower than or matching your current firmware version.
