My friend's girlfriend is importing BBS. Being the jealous, impatient person I am, I might do so as well. I'm curious though, what would happen if I ran it as a UMD through my 5.00 m33-6 (PSP-2000)? Would it mess with my m33, such as it updating to 6.20OFW or w/e? (Not quite sure I understand the whole 6.20 requirement...)
