Example (you click on the name of the game in your mind)

AA, all right

Your file name must be AA. SAV

Or AA.dsv

See which version of your emulator is.

If it doesn't work again

You have to download files, convert them and so on.

In short, the file name must be the same as the name of the game in your computer before it can be read.

The file type is SAV

Or dsv or something
