Hacking Save data file format error

[alogon]

I get this error when I try to load any game.
I've tried deleting the save files to make sure it creates a new one, but it doesn't work. I've also tried formatting the SD; in FAT I get a black screen, in FAT32 I get the error.
This error only appears when loading a game from touchpod.
When I load the game from Sakura (1.49a X 3rd):

• Upper screen: Loading game
• Lower screen: Two lines of file names written in red (NDS and SAV of the game I try to load)

Dsi Firmware: 1.4.2E
Core: 2.0.2
Flashcard: M3i zero

Help!

Sorry for my bad English, I'm spanish.

Is your flashcard a M3i Zero gmp z003?
If it is, just buy better card like an Acekard 2i or Supercard DSTwo. There is no fixing an M3i Zero gmp z003.

It is a GMP-Z003, but I finally managed to fix it. I've previously tried reinstalling the firmware, but today I installed an older firmware, and then I installed the newest Sakura. Don't know why, it worked. Thank you anyway.
