The save file for any game will be created/updated when you closed the emu, load another game, or reload (not reset) the game. However, you can force the emu to create/update the save file by using the function in NGZoom or No$Zoomer.

Just a bit of a side note, NGZoom requires you to have no$gba 2.6a and 32bit windows.

If you don't mind me asking, which function is that?

The function to force the emu to create/update the save file. Also, forgot to ask, which version of no$gba are you using and did you set the correct save type before you run the game? If you didn't set the correct save type, then you might corrupt your save, at the worst possible scenario.
