Hi. I have Pokemon HeartGold, and I started playing my ROM on my CycloDS because of the convenience (and how long it takes a retail cart to save). But I decided I wanted to start using the PokeWalker, so I wanted to put my sav file onto my retail cart. First I wanted to back up a sav from the retail cart so I could get the proper name for the save file (and to make sure it works)... and... it doesn't. I'm using Rudolph's 3-in-1 NDS Backup Tool, and it is able to recognize the ROM (and get the name and size), but it says "SAVE Type: Unknown" so it keeps asking me to confirm the cart, take it out and re-set it, but it always has the same problem. Does anyone know anything about this issue?
