Alright, I really can't figure it out. I created a /GBA folder along with the /GBA/SAVE folder. Placed a "backup" in there (the Castlevania 2 in 1), but I can't figure out how to load it. By watching JNGamer's YouTube Video, I downloaded the EZFlash GBA Loader. When booting up the Loader, it does the flashing and the copying and that's it. I don't know how to access the Nintendo DS Menu with the R4 inserted. Even when I change the options in the Nintendo DS, it still goes straight to the R4 menu. And, while I'm in the R4 menu, and do a Boot Slot-2, all I get are two white screens... I'm just an idiot, I'll look harder for now. Confirmed, I'm an idiot. EZ4 Client did the trick.
