Okay I've tried Rein, eepinator, cart_save, savesender and I've had no luck whatsoever backup up saves for any of my games. In many cases I've read them, but thats its. I've gone over pretty much every thread on this forum related to the topic, but I didn't find anything that helped me, (well lots of things helped me, just none with this problem) so here I am bothering everyone. I own the following; R4 DS, firmware 1.11 (auto DLDI one) EZ-Flash IV, this model EFA Linker II, this one 2GB Sandisk microSD 1GB Kingston miniSD Laptop with in-built Wifi One DS lite and a bunch of DS and GBA games With the above what is my best bet to do any of these? 1) Backup real DS games to a file 2) Write a file to a real DS game 3) Same as 1 and 2 but for GBA If anyone's had any success with this with any combination of that hardware please help me out or point me in the right direction, because I've tried so many times and so many different ways and had no sucess at all.
