| | The texture repeats over the terrain as expected,
but every other iteration it is flipped:
I'm guessing that's how the shader interprets it, for the sake of leaving out visible seams.
I was actually going for a "tiled" look, like old RPG or RTS games, embracing the repeating pattern.
I was going to use very low-res textures, and as you can imagine, it looks horrible with texture flipping.
I'm no stranger to programming, but I am to 3D, and especially rendering ^^.
Is the culprit in the "effect" file, or in my own code? How would I go about changing this?

Without any code this is just guesswork, but check your texture sampler in the effect file. There should be two variables, called AddressU and AddressV. If these are set to 'mirror' then this is the source of your problem.
What they do is, when the texture coordinates go over 1, they specify how to repeat the texture. 'Mirror', you guessed it, mirrors the texture. (By the way U and V are the texture coordinates, which could be likened to X and Y/Z coordinates respectively).
The solution could be as simple as to change the 'mirror' to 'wrap'. Also, if they aren't there, they could be set to 'mirror' by default, so you would have to add the lines
AddressU = wrap;
AddressV = wrap;
