A new version of marioEtool was uploaded with a fully unlocked save (all stars and all mini-games unlocked using the .dss file creator “SMDS.Save.Modifier.v1.0”) - this is for unlocking your Mario64 DS cart, just copy the included files onto SuperCard, run the nds and copy the save game from SRAM to EEPROM to unlock your Mario game.
