So I'm trying to load a save with Elite 4 defeated I downloaded (converted from gameshark SPS using VBA) and GBA Backup Tool (Running off R4 "Revolution For DS" in slot 1) will not write the file to the cart. Playing through the whole game has potential to be a very frustrating project knowing that my save might be lost after that point, so I wanted to do a test on my obviously bogus Pokemon Emerald game. It won't write any other .sav file either, but it will read the save data to the 128KB sav. It also dumps the whole ROM, which appears to be 32MB?! I thought Pokemon Emerald was supposed to be 16MB... GBA Backup Tool says the save type is FLASH 1M (128KB) Am I using GBA Backup Tool correctly: Press R to go to the Save Restore screen Press A (making sure the correct .sav file is selected on the top screen) to copy .sav to cart. I tried pressing B to "initialize save area" but it didn't do anything either: A red progress bar quickly fills but when I start game (after inserting it in a GBA), my old save file is still there.
