Hello, I'm new at this and I'm sorry if this fourm already exist. I just have a few questions... 1. Does the M3 Gba Expansion Pack work with an R4? 2. If so does it have problems with saving? Because I've heard that the Expansion Pack deleats the files when the battery dies. 3. Does the EZ FLash 3 in 1 PLUS work with an R4 or any other non-EZ Slot-1 Carts. 4. Also is there any Slot-2 devices devoted completly to GBA games and is the easy to use?(That all I care about. I don't care for homebrew, rumble, or browser.) Oh and I have a DS Lite and R4. Thank you in advance for your answers.
