::::Well, one interview I have to scan, but the RiviPSP Art notes and the Designer's Works should keep you busy for a while if you're not so fluent in Japanese. The other interview is a three page deal with the Shinichi Ito and Sunaho Tobe; I'll find the time to scan it within the next few days. Jaja's Blog may also have some info regarding Riviera's development, maybe, but most of it seems to regard YU, and it would probably only be stuff about the PSP version if there was anything.
