Hacking Digimon World save file doesn't work?

[Swifteye]

i've had a few games saves corrupt upon loading but ive solved the problem by saving in all available slots on the game so if one corrupts i just use the copy files but seeing as how this game only has one slot im kinda screwed and i really wana play it. the file doesnt necessarily corrupt but ill save fine in the game and then wen i turn it on at a later time the only option is "new game" and my file seems to have never existed. ideas/solutions anyone? (and no its not a faulty rom ive tried that already)

make sure you have enough free space to create save files and are you using the official 1.17 firmware, if so don't unless your card is a authentic dstt because it kills fake cards.
just to be safe use the unofficial dstt firmware 1.17a02 here http://gbatemp.net/index.php?download=6507 .
also copy your sd cards files to a folder on your pc format the card with the Panasonic formatter http://gbatemp.net/index.php?download=4003 then place all the files back on the card with the unofficial firmware if you do not already have it.
