I've played it and well... to answer some questions about what is translated.. you'll get the basics of this game's robattles and the very first 10-20 or so minutes of intro but after that nothing is translated. The character moves from the starting town to a school and pretty much as soon as you go to first class (15 minutes in at the most) nothing seems to be translated any more. The menu is partially translated, such as what each button does but not the header text describing the selected button.
TL;DR it is a bare minimum version.
As for obtaining the downloads, I reposted OPs .3ds and a personally converted .cia in the chaos site discord server so you're free to join that and get them there instead of that iso site.
