Atleast I cant get it to work...

I can explain the 'overlapping border' problem...

What happens is that the Wii expects the texture to flip itself at points that are off the edges. The same thing happens in Brawl with the Alloy models.

Your best bet to fix this is to take the texture, open it in Photoshop, and double the canvas size, keeping the original texture in the middle. Paste the texture in and place it on the edges, flipping them vertically or horizontally (or both). Flatten the image before saving a copy, of course.

Now, back in your 3D app, take the UVs and scale them down by 50% towards the middle (Blender does this pretty easily).

It's a kinda ridiculous workaround, but it works.

You don't really need to fix Eggman. It just makes use of a common type of texture tiling that has been around since N64. I'd be really surprised if any modern modeling program didn't support it.
