OMG! And I thought that basic iostream is lighter then printf... Yea, stringstream is not there, but it is obvious ...

But you're right. I have no reason not to try use it. Thanks ...

I'm just beginning programme to NDS (but in C++ I'm programming a few years) and I'm thinking about virtual methods. I made a simple video engine for PC game using virtual functions, co I can later change graphic library from OpenGL to Direct3D or so and so I did with classes for images, textures ...

When I try compile project, obj files are created, but it cannot link. It writes some "undefined reference". I did set linker setting to link nds lib. I know ...
