OK, did that, now the canvas is one px too small, and I still have all kinds of different colors instead of all black.

Forgive me if I'm wrong, but since black = 0x0000, doesn't: Code:
if (canvas[i][j]) {
fillArea(i*zoom+x, j*zoom+y, zoom, zoom, canvas[i][j]);
}

Can you Pastebin your current code so we can take a look? Just in case something went wrong with the off-by-one fixes.

Any ideas?
EDIT:
Figured it out... apparently c files should not be included.
It's a problem with the includes.
Code:
You should not include *.c files directly, instead you must include headers (*.h) corresponding to the .c/.cpp files you want to include. You'll need to manually build the .h yourself, from the definitions of the your functions on the *.c file (there are tools that automate this but I haven't had such a great experience using them... I guess using a IDE for developing makes the whole headers thing easier).
EDIT:
Yes, it's this, didn't see your edit (blames browser cache).
