Nostalgia freezing

after about 3 hours into the game I'm getting some random freezing...it's happened about 3 times now at various times. Anyone else having this problem?

Which card and firmware are you using?

Have you tried formatting your SD card. I was having problems with Nostalgia but it started working perfectly after I formatted my card.

I'm having freezing issues, but I'm only in the sewers at the beginning. After a battle, it freezes at the black loading screen - not every time, but I can't get past like three random battles without it happening. o_o?I'm using a DSTT with unofficial firmware 1.17. I'm going to try reformatting my card, then if it doesn't fix it, rolling back to the official 1.16 firmware.[edit] Yep, reformatting worked. ;3
