I started a walkthrough of Light Platinum last year, at the same time fixing bugs (mainly movement permissions, but a couple of graphical bugs as well as adding a Pokémon that could not be caught, anyhow, anywhere). I took a break in Serenity City and stayed there through a spin on Black 2 / White 2, which I've now beaten the E4 on and am delaying post-E4 activities. Since Light Platinum is Hack of the Year now, I figured I'd best get back to work on that. Deserves a full walkthrough like some of those found on GameFAQs (heck, you never know, maybe I'll even try to have it hosted there!).
