I have DSi XL and r4i 3DS. I tried many times play Pokemon Black or White. But it keep freezing after leaving Striaton City. I've downloaded dozens versions of rom but it's always the same. Before reaching Route 3 game working perfect. But when I reaching Route 3 it keep freezing randomly. When I run game after that it allow me to play some (short) time but freezes repeats. I have no idea what to do. I've downloaded newest soft for my r4i 3DS but it dosen't works. Oh, and sorry for my poor english.
Did you patch the rom if you didn't its checking the cart and freezing because of a faulty rom dump the hack roms seem to work better
