One fine day, which is today, I was feeling good cause I did good things. So I decided to celebrate by changing the icon picture of SSF2's file which contained all my data and screenshots of the game. I right-clicked and pressed properties. There was a check box "Visible" and there was a check inside it. I took out the check and clicked the "Apply" and "OK" Button.
And when I looked for the file, it was gone.I tried clicking the place where it was but it wasn't there.
Anyone know how to fix it? I cant play SSF2 if this isn't fixed

Try PMing a dev?

i dont have ssf2 installed so i cant say for sure but you could probably hit the start button and type in "SSF2" and launch it through there
or you could redownload it

Idk, sometimes that doesn't work.

Open up your file browser and type in the directory

This. Re-downloading SSF2 should help. If you happen to have a file for your saved data as well, make sure to import it into the game after you open SSF2 (if the unlock-ables you got aren't there).

Look up a tutorial on how to see hidden folders.
