I'm not sure if you can put covers on usb. The covers folder is in hdd0/game/BLES80608/USRDIR/covers.
Yeah, I know, btw it can load from USB (it's written in MM main page and here [check page 4,5 or 6] and I prefer that way cos many covers are wrong and it's more easy to manage them :-)
I made a Dead Space theme already, but if you want a SP2 theme, then ok.
i currently use the dead space theme and love it .I just would like something with 2 in it to stay current with the game of the day i'm playing hahaha. And thank you for all your hard work man.
