Well, most of these games aren't and never will be translated, it's a sad thought, but true. The two routes you can take is either a) learn to read Japanese, though the longer of the two, easiest the best. Or b) Use Atlas+agth to do a rough, but to some extent readable translation. While it is alot faster then learning the language, it will not give you the most accurate translations all the time. But you take what you can get right?
Also, if you want to begin grabbing these games, download them, and burn them to disc/external HDD till your ready to play them. I don't worry considering the fact I have 3 internal HDD's (200gb, 300gb, 750gb) and one external (750gb). One can never have to much harddrive space!
