...when you have a really bad day on Pokemon? Well I have... three times! I bought Pokemon Emerald about 6 months ago, and since then I've had it become corrupted three times, even when I've saved.

The first time, I got to the Battle Frontier, saved, and rested, turning it back on to find my file corrupted.
The second time, I went into the Trainer Tower. Again, file corrupted when I saved.
The third time was today...I had just gotten to the Battle Frontier AGAIN...when it corrupted, even though I had done everything to save.

Now, I know I'm just ranting, but on this, I doubt I'll buy another GBA Pokemon game again...I just need to wait for my Diamond to come through next week

Yeah that's weird. I've bought every Pokemon game since Red/Blue. None of them have ever gone corrupt. I suspect that deceiptful devil Magnetism is to blame somehow. What's nearby where you're keeping your gameboy?

I'm keeping it near my computer at the moment, just on the desk, so if there is a magnet nearby, it'd be screwing with that...which it strangely isn't...

I dunno, try keeping it somewhere else. Like another room.
