Dark matter appears based on observations and theoretical analysis, in published papers to be an incorrect mechanism.
The people that do simulations of galaxy-galaxy collisions as far as I know aren't confident enough with their models to make this sort of statement. There are several other independent mechanisms that favor dark matter, and no one has quite gotten any of the alternatives (modified gravity) to work quite as well.

Of course may be something that we didn't think of, but it would be interesting to try to think of something that don't fit into either dark matter or modified gravity which isn't already excluded by observations. You are welcome to try (no sarcasm here).
