Re: super robot taisen og sage frontier First, take a look at our rules. https://www.romulation.org/forum/index.php?topic=4312.0 Then take a look at http://cheats.gbatemp.net/ They have updated Cheats databases for DS games.
Are you using a flashcart for your cheats, like R4, M3 or whatever, Acekard, etc? If so check http://cheats.gbatemp.net/ and downloading the the cheat files, put them on your card. If not, Are you using a Action Replay?
