Well, outside of the KN based on one of the replay series (Tanodan), there is the DS game based on one of the novels (which did get translated, said Novel).

said DS game well... ...the lead translator isn't exactly fond of it, saying it's a very VERY stripped down version of SW2.0...

...though, right now, said Translator is working on a few other books, and the PC-98 game based on SWRPG.
