I understand this question has been asked a lot in different ways, but I've looked through all the threads for hours and I still don't understand my problem, as I'm a complete noob when it comes to this stuff. It probably has an easy answer. I have the regular R4 for NDS/NDSL and it runs wood. Whenever I played GBA games right from wood, it would always say the save file for my game has been corrupted (Pokemon Emerald). So, I tried GBA exploader. I have no idea how to save using this, I feel quite stupid, whenever I turn off the NDS and go back to GBA exploader to save the game by pressing B, it says it can't find anything to save. I apologize for my extreme lack of knowledge in this field, but I figure if anyone can help you, it's you guys.
