You've come to the right place.

To be honest, I actually spent some time working on an English translation patch for the two King of Bandit Jing games (and yes, there is an Angel Version and a Devil Version, just like Pokemon). Unfortunately, the print routine is so obscenely screwed-up that I can't make heads or tails of it. I want to hack a VWF into the game, like I did with Sylvanian Families (another obscure GBC title ^_^), but it's going to take some time and effort, and presently it's on the back burner. Right now I'm working on Death Note: The Kira Game for Nintendo DS, and I intend to tackle Death Note: L's Successor afterwards (and possibly the "Rasen no Wana" prequel as well)...King of Bandit Jing is a project I'd like to take on sometime, me being a Jing fan and all, but you'll have to wait a while.
