nice job for keeping good progress in this job .
can i give you some suggestion: opening some google document of SG2 japanese script who people can freely translate it,
so you can get many people, people who knew little japan languange, helping you translate it, and edit and correct it together. it will be faster, right?
someone like me who willing to learn japanese but only knew a little about japanese, if everyone who like me joined together
(i think there are many suikoden fan in the world right), it will help cut the time for your group too.
