no$gba.inp =/= no$gba.ini
You will get no$gba.ini file if you save the settings. Since you don't have that file, you don't need to worry about it. This just means that you are using the emu's default setting.
Anyways, try using No$Zoomer or NGZoom. If you still don't see the save file, then try forcing the emu to dump a save file using the function provided in No$Zoomer or NGZoom.
