Stuff I have written in C++ for the NDS - All source files included
My first DS Application - a spirit level application - V1.0
Makes use of the DSMotion card and DSerial card (Thanks Bram!).

R4DS Spectrum Skin
Not really programming but it fits in with the NDS coding side - a ZX Spectrum theme for the R4DS card.
I believe this works for other cards also like M3/Acekard.
