2 black screens when I try to load pokemon diamon

I'm using the no$gba emulator and I started playing Pokemon for an hour or so then used the in game saved, it said save successful, so I exited the emulator. I came back later, loaded it up, and press continue and press on my file that I saved earlier. When I do all that comes up is two black screens, so I cant really play the game. Do i need something else installed or what wrong?
TY

 

don't worry, it's nothing up to you... it's just the nds emulation it's at an early stage, and almost every people have the same problem... search throughout the forum and you'll eventually find something to correct it... an IPS patch...
