2d game programming

Seems like every Dx9 tutorial out there deal exclusively in 3d ... except for the occasional thing about textured quads ...

Is there like, a magical super place somewhere on the intarweb with 2d game programming resources? ... I'm trying to hack together a shmup ...

My mom is portable

Portable code is nice.  I currently use linux, but many of my friends use windows, and we like to play a capture the flag game I made in SDL.  If I had not used SDL or OpenGL, I would have had to learn two libraries.  Of course I probably would have made my own library to call these other two libraries like SDL does, which would have just been wasting time.

Just use portable code.  It saves time.
