no$gba revenant wings saving

using NO$GBA 2.5bhad set the NDS cartridge backup media to eeprom 64 kbytesi can finally save in game but when i start the game the next day when trying to load the save game from 'continue' it suddenly erases my save game... (hitting continue does not take me to the game loading screen)Anyone had tried to successfully save and can continue playing without this error?Thanks in advance

the backup media is set to the incorrect setting.

thank you, so can anyone tell me what save type works for them on no$gba for revenant wings so they are able to load their previously saved games? thanks again
