Quick question for final fantasy IV (4) for NDS

Just downloaded it off this site :]
I researched because this became an annoying problem. I've just started the game and I wanted to save (Which I'm sure you only can on the world map right?) and I ended up closing down my game on accident pressing random keys trying to get it to work.
I'm new at playing these with a keyboard so I don't know what key is the menu so I can save my game.
I tried 'x' but it just switches who I'm controlling on the map.
I'd appreciate any help or tips.
Thank you.UPDATE:
Now I tried to keep playing and I'm stuck because I can't get out of a menu. =_= Is my download just corrupted or what? I tried pushing every letter on the DS x,b,y,a ~ Nothing's working >.<

are you using no$gba emulator?if yes, then when you click the option tab, you can see control setup and emulation setup.click control setup and set your button to what you want.then click ok.After that, you can click option tab again and click at the "save option"

I'm not sure, because I'm so new to this.
I'm using WinDS Pro

WinDS Pro
-That's just a compilation of DS emulators and etc...and you can't change the controls I think...-Get the clean version of no$gba here:
