How far did you get with that, anyway? Finished Onikakushi yet? I might start working on doing that myself. Glad Matsuri FINALLY has a release date though. It's taken them long enough, though hopefully the wait will have been worthwhile.
And yeah, basically it's a case of whether you can read Japanese or not. If you can't, you're extremely limited and will just have to follow the Minagoroshi patches or get to work learning the language. They're not very expensive and all you do is click and read text basically. If you've got a Paypal account (or can get one) you can get all of them from Paletweb.
