Paper Mario

I was playing Paper Mario and suddenly it froze, this happened in the Tree where the Punios live after opening the door of the cage where the elder is imprisoned, I wanna ask if someone is having the same problem and how I can solve it.

The emulator is Dolphin 2.0 and the specs are the default specs I didn't modify anything.

It is an Intel Core 2 Duo @2.00 GHz, 3072 MB RAM @800 MHz and a 512 MB NVIDIA GeForce 9700 GTS
