I'm not sure if that's the place to ask, but I've downloaded MV_RadarIcons.vp. When using it, I felt the icons were to low-res, so I wanted to edit them. When I extracted the vp, I got a bunch of dds files. I've looked on the wiki, and didn't quite understand how I could convert them to and editable format and back to dds... Can someone help?

Several ways.  Paint.net, Photoshop with the plugin for dds, Infanview can convert but not convert back, There is also a command line utility.  I suggest you check the modding forum for more info.

GIMP's probably you best choice for a good image editing program free, but if you just want to convert, plenty of things can do that.

Yeah, Gimp is one of the best free tools for this task.
Alternatively you can use the nvidia commandline tool, very powerful, as it gives you total control.

ATIs Compressionator does the same.

If you use GIMP, you'll need the dds plugin.

Also, you can directly edit the DDS files with GIMP, no conversion needed.

Rodo, that's been said already!
