Homebrewing (on the DS)

At work I am tasked with playing a DS for 8 hours a day so you'd think that the last thing I want to do is muck about with it after hours. Well, you'd be wrong - Portrait Of Ruin is awesome. However, I'm lagging a bit behind in it - since on New Years Day I received my R4 slot one cart and shortly after that I installed DevKitPro so I could jump on the homebrew bandwagon. Having a good grasp of C and C++ it hasn't been too hard to jump in and have simple things work. Maybe once I've done one or two small programs I'll put something together and bring it to one of the developers at work - maybe I'll get to convert it for use with an actual Nintendo devkit. I'm very interested in seeing the differences between the homebrew and developer set up. That however will have to wait - Dracula is calling me...
