It is not possible unless u reach the Pokemon league.
the only way that i know is if you have the Pokemon diamond ROM where you save the .sav file twice then trade off that game then overwrite the new.sav file with the old one
ussually it will load the last save game and it will fix itself
uh overwrite it.
NO!!!!!!
Unlike past Pokemon games, you have to delete you existing save file before you can save a new game. You can do that by holding Up+Select+B on the title screen (where it says Pokemon Diamond or Pokemon Pearl) Deleting the save takes a minute or two
no i guess ------------------------------- It depends on how the cartridge was made. There is a slight chance that its possible, however most likely you Pokemon diamond won't even recognize that there's even a cartridge attached in slot 2. It could also wipe out the save file of your gba.
all you have to do is start a new game and save on your new game file what is a new game file?
you just save it as usual and when it asks to overwrite the file you choose "yes" then it'll save the game,that's it
you have to do something on the mainmenu and then it will be deleted but it takes a while for it to delete the previous save file
well i had this problem once. if its on the emulator u have 2 make a copy of the Pokemon pearl or diamond file and paste it in the battery file that is created when u downloaded the vba file. then save ur game and restart it and ur file will be saved.
You cannot save a Pokemon game during a battle.
you save and overwrite the file
