I have my Pokemon Black english rom for some time now, it works.... but it just freezes too much. Like when i catch a sandile or something, then go in a random battle and the game freezes.... thus losing my progress. I'm using M3 DS Real with the Sakura firmware. Is there a patch to prevent those random freezes?
Maybe using the (USA) ROM may help... Both (U) and (E) versions are region free for language Are maybe a backup of games and saves and a good format using panasonic SD formatter
Try installing a secondary firmware on your M3 Sakura. Its either the YSMENU/TTMENU or the Wood. Run the game through that secondary firmware. To find the secondary firmware latest download, instruction, and compatibility list, you can find it in the FLASHCART Section.
