Are you using the latest version of Desmume? Blahblahbla more info?

yes it was the newest

Which card? this emulator does not need any card... what exactly are you talking about?

sorry i was mean after i save and exit, when i play it again i don't found my saved data.
i think it's not a card sorry but the save type

Try manually configure your SaveRam directory into a folder, the save type for the game will be automatically selected on DeSmuMe.

Open CONFIG menu and select PATH SETTING. Change directory setting for ROMS, SAVE RAM etc.. Make sure you creates subdirectory for Desmume first.

ummm i have a new problem
when i give my desmume to my friend
he can't use the control button
Need help now

Easy as pie! Open CONFIG menu and select CONTROL CONFIG. Change button setting for A, B, X, Y, L, R, SELECT and START only. Don't touch another command. For myself button config, here!

Spoiler

A button = D key. B button = C key, X button = S key, Y button = X key, L button = A key, R button = Z key, SELECT button = SPACE BAR key and START button = ENTER key

Quit emulator, delete DESMUME.INI file, open emulator back and reconfigure control back. If any problem, visit this site!http://wiki.desmume.org/index.php?title=Faq
