Can't save for the game 999

Hey there. Whenever I save it says "saving" and seems to save. But whenever I restart NO$GBA it shows no save data. Help please!

Did you properly quit the emulator( File -> Exit, etc) after playing it?
Try using the Save Battery File option( File menu) after saving the game.
Reboot the emulator and load the game again.Please remember that, the save file won't be updated if the emulator crashes(even after you have saved it)
Oh, this game also occasionally crashed at random point.

I properly quit the emulator. And I can' find the Save Battery File.

You should be able to find it on the 'File' menu of No$Zoomer.

I use NO$GBA is that different?? Sorry if these are stupid questions. Thanks for the help!

Not really, No$Zoomer is just an addon for No$gba.
I recommend you use it.Try using a fresh copy of No$gba(No$Zoomer), pretty sure you can find it on the tutorial section(the full package).
