I am playing Pokemon Black 2 patched AP on my R4i SDHC 3DS it freezes in the third city soo much randomly. Even if I come to trash can and I push A it freeze when the texts is coming on screen. Any fixed ROM that will not freeze with this game ? (I had C-GEAR on) Maybe my card is too slow (2 games worked slow Naruto Shippuden Rumble and Urban GT)
