Is there some new kind of pokesav for these games? Whenever I try to modify my BW2 sav file with the old BW pokesav, it tells me in-game that the save file is corrupted. Any thoughts?
havent tried it but some are saying pokegen is working: http://projectpokemon.org/forums/showthread.php?6424-Download-link-and-information
Use Pokegen from Codr. v.3.1.2 and above has been suited for use on Pokemon Black 2 and White 2. Make sure that you have made a save file by saving in-game. You can edit most common save file types such as .sav, .dst, .ds, .duc. without having to convert it. Of cause other extension type will need converting.
