Shadowshade

Hello! I've recently come across a restoration patch for If My Heart Had Wings: Flight Diary, and I wanted to translate the restored scenes within said patch, as they are all Japanese. I have extracted the Rio.arc file and am left with .ws2 files, but for the sake of me, I can't seem to figure out how to open them properly, is there a specific tool (next to WordStar itself) to open these files? Cheers!
