Help saving on DS Emulator

I need to know if there´s a way to save DS ROMs?
I mean like this:
I have Digimon World DS, but when I press SAVE it says something like "cannot write data". VBA can save such things with "shift - F1", but is there something like that for No$Gba?
Please tell me quickly... please...

@Admins: I don´t know if this is the right section, and you can delete or close this thread, but please after I got an answer.
I BEG YOU PLEASE!

Right click on any of the screens and click "Save State" using the No$Gba or with the DeSmuME go to File > Save State As...

Yes, I´ve tryed that, but that just saves screens, or how can I run it when I load it?

As much as state saving works, it is a work around. I'd say its a big no-no to only use state saves as sometimes they do get a bit off and then BAM your game is gone forever.

I'm not sure how to get saving working, but its worth the effort, the pain losing my FFTA state save caused me taught me that lesson.

In NO$GBA try changing the save type under the settings, looking up what savetype Digimon uses is a good start, then set it to that.

just use iDeaS. Saving always works there. just set in properties where to dump the save files.

have you tried doing a forced save?
