By mastertcs on Jul 13, 2016: #1 Hi I just bought a jailbreak ps3 2 weeks ago so I'm really new to this and my knowledge about ps3 is really low. I want to use some cheats using artemis but I can seem to make it work all. I followed all the tutorial and video but can't make it work. the problem I'm facing is when I try to use artemis with a code selected it black screens. I tried using artemis first with codes selected and when I tried to load a game using multiman it also black screens. with out artemis multiman and the game works fine (I'm playing tales of xilia 2 English version) my system software is 4.80 artemis is r4 on multiman it said firmware 4.78 firmware mode cobra 7.30 I think my ps3 is a fat/ old model I also tried a post that said to disable the systemcall 8 and I did that using webman mode and I choose to disable permanently I hope that does not ruin my system. Please any help will be appreciated.
