Is there a way (preferably in PAlib, but libnds is OK as long as there's documentation) to plot directly to the screen, like, just turn one pixel on or off, set color, etc? I want something that draws lines to the screen, and plotting pixels seems easier than preset sprites...I heard about some kind of framebuffer mode in libnds, but I have no clue how to use it.
Where can I find general libnds documentation, anyways? I'd like to read a command reference of it or something, if one's available.

Yes there is a framebuffer mode. Extended rotation is similar to the framebuffer mode but offers extra features like rotation and scaling.
A third way is to draw hardware accelerated lines using a 3D background. If you draw a triangle where two vertices are equal, a line will be drawn instead.

Ok, that's good, now I know that it is possible, but what libraries support these functions...are there any command references or tutorials for this?

"libnds" has no documentations, only a set of defines and helper functions.
for frame buffer, or as called "extended roto-scale background".
Too lazy to comment the code:
| Code: |
static inline void putPixel(u8 x, u8 y, u16 col) {
BG_GFX[x + (y << 8)] = col | (1<<15);
}
void initVideo()
{
POWER_CR = POWER_ALL_2D;
DISPLAY_CR = MODE_5_2D | DISPLAY_BG3_ACTIVE;
VRAM_A =VRAM_ENABLE | 1;
BG3_CR = BG_BMP8_256x256;
BG3_XDX = 256;
BG3_YDY = 256;
}

it's super easy with libnds and even easier in palib (bitmap modes / framebuffer mode).. Can't you search a bit ? THere's plenty of palib documentation and tutorials.
