i did, but it still fails. I'm using O3DS and a fowarder, i assume that might have something to do with it?
Before i created the folder it said "folder missing" now it says the save and loading is working, but it doesnt
Maybe you should try going through a "data" subfolder, it works for me.
1.create a directory on the root of the SD card called: data
2. create in the "data" directory another subdirectory called: ngpds
3. in the "ngpds" subdirectory put the bios and roms
4.reset the emulator settings by selecting in the menu "option" -> "machine" -> neogeo pocket color (the bios that you put in the ngpds folder)
5. in the "files" menu select: save settings (to create a new .cfg file, don't forget to remove the old one)
6.turn off your ds, at this point, normally the emulator should recognize the new path (root -> data -> ngpds folders)
7. launch the emulator then select a game, during the game, touch the bottom screen or press L + R to access the "files" menu then select "save state" normally the emulator should create a file with an extension .fla
To resume a saved game, all you have to do is launch the selected game, start a game, access the menu and select "load state
Now all the files concerning the emulator will be in the ngpds folder (bios, roms, .cfg file, .fla files)
