dwi files the same as .msd files?
The formats are very similar. When we were adding in the new features of DWI (Hold Arrows, Solo Mode, Background animations, etc.) we knew we needed to change things in the file, which meant choosing a new extension since the stepfiles were now proprietary. You can rename a .msd file to a .dwi file and play it in DWI, but GAP values from .msd files will not work very well with DWI; so if you’re converting your old MSD files you’ll have to Use The Force and set new GAP values for each file.
