The vast majority of characters don't have an Arcade storyboard; it's nothing to fret over. Heck, even Goku Z2 and Vegeta Z2 don't, and they're two of the very best characters (minus their AI).

.def and .cns can be opened in Notepad. .7z can be opened with programs like Jzip, 7-zip, etc.

Personally, I think you should get Fighter Factory. It can read every file that makes up a character (note: .7z is not a character file, so you'll still need something like jZip and 7-Zip).
