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 ...

Slower: Of course, I was just counting Linux on PCs and Windows. Problem is, something portable is not specifically designed to take advantage of each platform and do things the way each platform "likes" them.

Less user-friendly: Tends to be so because most (all of what I've seen) portable GUI libraries provide less agile interfaces and less versatile controls in some things like keyboard control, for example. So unless you're willing to develop a custom portable interface that accomodates best to your application, you'll have to stick to interfaces usually slower than what can be done on native Windows and native X/KDE/etc.

Problematic: Installers aren't really portable, so you either make a mess, or work several times on these. Then there are oddities and special features that will make it experience strange behaviors or sluggish performance, and certain features from some OS you'd kill to have in some other. Because they are not specifically designed for a particular OS or system, something unexpected is a little more likely to happen, like not finding a color mode you need supported by the hardware drivers or whatever.
