Truobles with couple of NDS games

Simple problems, but I don't know very much about emulators, so..Pokémon Ranger:
In Summerland when I should go to the mission with Aquamole, the game freezes after I hop into the submarine and the mission starts. Music stops, but waters animation still runs, but that's all.Final Fantasy Fables- Chocobo Tales:
This one is really embarrassing.. In story mode when I try to revise my card deck, I can't pull the cards to the deck. I should pull the card with stylus to the upper part of the screen, but it won't work. I can't figure it out, why the cards won't go to the upper screen.Pokémon Ranger - Shadows of Almia:
Simple, again, the game won't save. I have to use save states in order to play, but I can't beat the game and get the special missions, because of the save states.Pokémon Paltinum:
Same problem as with the Pokémon Ranger Almia.I'd really appreciate if someone could give me some advices. Thanks!

What emulator are you using to play these games? version?

Oh, stupid me, totally forgot that. Sorry!
I'm using DeSmuMe 0.9.4.

Use No$GBA 2.6a and change the save type to Auto, tried it on Pokemon platinum and no saving problem. :)

Okay, I'll try that with Platinum, thanks. ^^

Tried playing this on no$gba emulator?... oh and don't use savestates so much, try saving the normal in-game save function.
