FE: Shadow Dragon. How do I start?

I know I probably sound like a newb or a dork or an idiot or just plain dumb, and I don't mean to offend anyone else who has this problem, because I'm clearly having it too and I don't really think of myself such a way......but for some reason, I start Fire Emblem: Shadow Dragon (for the NDS, USA version), and after I hit the Easy option, it goes to this scene, or rather, setting, with some ink pot and quill and what looks like a map or something, and plays some music...And nothing happens. No matter what button I press, I don't get anywhere. Then again, I try to press the traditional A and B buttons, and I'm still trying to work out the emulator controls, I guess.What button should I press to get it to move on/keep going? Or, even though the music's still playing, is it freezing on me or something? I'm kind of confused...

What emulator are you using? (version, etc.)

The NO$GBA version 2.0 with the NO$Zoomer... thing.

Update to No$GBA 2.6a

I think that is what I'm using. The Zoomer's 2.3.0.something or other, I think. I remember being told to update before, because I had problems saving, so I did...I said 2.0 because the actual point doesn't show up as far as I'm aware...

Yeah. I just checked the page that I downloaded it from last time I had an issue, and I am using that version, so I think the problem lies somewhere else.

Are you sure you are pressing the correct buttons? Are you using a keyboard? What keys do you have mapped to what buttons?

I set them myself. Up is up, down is down, right is right, left is left.To match the other GBA emulater I had and make things easier, I made the Z key A and X for B...S is for select
P is for start ('cause to me it reminds me of pause)
L and R are L and Rand enter is for X and Y is Y...But I haven't tried pressing all the buttons I guess. Common sense told me A or B would typically start something...Is there one that I should try pressing, besides A or B?

Start?Or click on the screen (your mouse is your stylus).

Aha. I've been trying to press Z X and enter, I think. I don't know if I tried P (start) yet :(.I feel kind of silly...but there are some things that can be right in front of me that I don't tend to see without help, even when I try and try again...I probably would have figured start out sooner or later.I don't know if it works or not yet. I'm redowloading the game now. I'll try it and if I'm still having problems, I'll let you know.Thanks ^^. And please forgive me. I can be a bit of an airhead sometimes ^^;.
