I think I'm better off buying the JP PSP version and just calling it a day.
i bought the digital download but the UMD version has started hitting the bargain bins - i am considering picking a copy up "for science" seeing as it's never seeing the light of day -ever- outside of Japan.
Re: Translations/scanslations - my japanese is pretty meh but whenever i've delved into any conversation online about scans/trans they all seem to chase eachothers tails in a "but this has to be the exact word for word translation and you got that word wrong it should be...." hence you end up with truly awe inspired dialogue like "this is the first time we are meeting! I am the much rumoured FUGEEFACE, please to meet you. you should die. It's finished!"
