NDS Pokemon Blaze Black 2 & White 2 - Nintendo DS Game with Box - Region Free

Game freezes way too often.

I want to give it five stars, and it could be the 3ds I'm playing it on but it freezes quite often that seems to be the only issue, again I'm uncertain if it's because of the 3ds I'm playing it on or if it's the cartridge. Anyway it brings a lot of challenging battles very fun to think of strategies to try and beat trainers. It feels like I'm playing Pokemon White 2 for the first time. Even though I've played it over 10 times.
