Sorry, I accidentally deleted your attachment 1. Why are you using 0.9.11 instead of 0.9.13 2. Are you using E or U (or JP..) version of the game 3. For your information, this is not actually a .dsv file. It's a raw .sav file with the wrong extension.
use a different emulator. or get a refund for your game: it's defective.
