3rd Gen Pokemon Advance Gen in Nintendo DS

Does anybody here experienced this? I bought Sapphire so I can transfer them over to Diamond. I pop it in my DS, play the game, and save, but the next day (when the clock strikes twelve midnight in the game), the saved game goes poof! Gone. The game just tells me "The save file has been deleted..." with a rather cryptic tone, then I start a new game.

The save file only exists for one day, so I can still load the game when I play it during the same day I created it. Funny, the game gives me the "The save file can be loaded... The game can be played" message (I don't remember that when I played Sapphire in GBA) when I start to play. When the day rolls over, the message then turn drastic, telling me the game, judging from the message, deleted the save game.

Any idea why this happens?

not sure why it happens. is your ds flashed by any chance? another way i could think of is just play at 11.55pm and by 12 am you'd have started and then save after 12. could be a bit had, especially if you have school and have to wake up early in the morning. My DS stuffed up before I opened it so I'm getting a refund, I hope.

My Pokemon Ruby game did that (I bought it off of Ebay, and it was pirated >.<).

i dunno why it happens but if you really want it to stay... before you go to bed put your ds on your charger start playing the game and close it over when you wake save it and turn it off =)

huh. i guess i can just always set the clock so it'll be 12 midnight at a more convenient time, so i can play it right before 12 and save it after twelve. lets see what'll happen. the cartridge is a knock off, i think.

Maybe you should get a refund dude O.o
That's definitley not how it's suppose to work.

Looks like you picked up a pirated version. What does the cartridge look like?

Guys, I think figured it out. I'm using a DSTT'ed game pak for my DS. Turns out everytime I run the game pak, it deletes the save file in any gameboy advance inserted in the DS advance slot. It did that to my Pokemon Sapphire, and Pokemon FireRed. That solves the mysterious save file deletion, but the 'The save game is ok' message seems a little puzzling still. scratch that - really puzzling. I'll update on this when I have more info.

you know best thing's to use emulator and play :D

Usually it means the game is a fake, or in some cases it's some version of the ds lite that does it
