alright chances are high that im getting a used psp. BUT BUT BUT BUT BUT, the umd catridge doobie is broken, it originally was ripped off and the owner (being a complete asswipe) superglued it closed and crossed his fingers hoping it would fix. in the end the case was glued shut and we aren't able to open it =). it has a 2.6 firmware on it and i have a 2.6 downgrader somewhere. so the question is, do we need the UMD catride doobie for any reason at all? i don't want to regret buying something that won't work for me.
