I want to use cheats on some of my games..is it possible...If not is there anyway I can do it?

 

ok how?

 

I assume you could use the 3in1 link to backup and restore pokemon diamond saves with a 3in1? or does that require a slot2 that uses a micro card?

 

Dump the save with rudolph's FTP dumper if you don't have a 3in1. Then use shuny's converter if your flashcard uses a different save format.
