There are RTK 1 files available on the yahoo group website but I haven't seen anything for RTK 2 on any piece of software. Supermemo is a bit of a hassle to get used to but once you learn how to do the basics then you forget about the difficulties you had pretty quickly. The advantage is that it's supposed to use the most sophisticated algorithms for spacing repetitions. Whether that's true or not I don't know but it works well for me.

The kanjitown template in the yahoo users group has all the onyomi info, but it doesn't have the compounds. Funny, I swear I posted a spreadsheet with kunyomi too. I think there's one in there posted by another user too.
