Games hang! Need help!

I was playing Professor Layton and the curious village and it hung in the middle of my game!
Same goes to touch detective 2 1/2... It couldn't start Episode 2 from the beginning. Just hung there and not proceed!Whats wrong? My disk full? cant load any further or my r4 got prob?
Please help me ???Thanks :D

This happens to me too and it only rarely happens, theres really nothing you can do about it just make sure you save often. One thing that i notice is that the only time it does this is when i leave it for extended periods of time closes or if i bump the micro SD card when its in the back of the cart.

thanks for ur reply...
But i cant continue my games anymore! no other way to solve this?
