this is the biggest doubt that i have now,and didnt clarify me since the beginning
im using 4.66 cex standard edition by darknet....here is the thing some homebrew applications like psp games require cobra cfw compatibility but when i want to switch mm to mmcobra using multiman ..it says your cfw wont support cobra thing ..but previously on rogero 4.55 it switches between noncobra to cobra easily ..

and another question
if i install darknet 4.66 v1.02 cobra edition cfw will it be the same as standard one that i'm using right now?? i mean in terms of loading the game and all

please somebody explain in detail ..and my ps3 modded with an e3 flasher..
thanks in advance
