ok i went from 3.55 cfw to the rogero 4.21 v1.09 cfw, i only have one game on external so far and its AC3. well i keep getting kicked out to xmb. i used unsanes eboot fix on the game to and still no go. i see on this site there is a dex fix for that game. my only issue is i aint sure if i am cex or dex, i dont know what that stuff is all about . latest multiman fix too.
