Hacking Data could not be accessed?

[babyybee]

I loaded a couple of games on my DS (R4) but only some of them work. The others, I got this messege: "Data could not be accessed. Power Off the DS and reinsert the Game Card." I thought that it could just be the game but I loaded the same games on my other DS and it works perfectly.

What's wrong?
How can I fix it?

Are they all nds games or are some of the home brew games?

Whats your firmware? Be sure you have the latest (1.12) and reformat your card.

This would solve your problem.

It's because you're playing a game that requires the arm7 Fix. I assume it's Worms: Open Warfare 2.
