3rd Gen I miss my marshtomp

I've raised my Rayquaza to 97 a lot of times but the game gets deleted AGAIN. So, Now I don't play it anymore.

Is your game pirated? Is the game pack dusty or it has lots of debris inside?

I've heard of this happening before, so its not unusual, but I don't know how to fix it.
Sorry.

I'd say it was a ROM written to a re-writable GBA pack, probably bought off Ebay. Or Nintendo's factory just stuffed up on your game.
Charging in a thunderstorm did nothing, because you where able to save throughout the game.

it must be a eletricity discharge on ur ds when u were saving...
u must be careful with thunderstorms... u r lucky than didn't lost ur ds

Nope... the DS has very little saved data on it. The chances of someone losing their DS to a thunderstorm is incredibly slim.
