Zelda Issues G6DS Real

Hi, I'm a G&DS Real user (lastest firmware v 2.3) just downloaded the new Zelda Game and it works great (no soft reset tough) i played about half hour then when i turned off the console and tried to resume the game the common "memory could not be written, etc" text appeared. I think there's some kind of saving/memory issue. If any1 could help me with this problem plz I just don't wanna play the whole adventure w/o saving or using the sleep mode :D hehe. Thx in advice and sorry for the english (spanish is my first language)

Have you tried the arm7 fix?
