How can you save a second game of Pokemon soul silver on Dsi?

You can't save a second game of Pokemon SoulSilver on a DSi, but you can save multiple profiles!

Here's how:

1. Start a new game.

2. Before you save for the first time, go to the Options Menu (press Start, then select "Options").

3. Select "Save Data Management".

4. Choose "Create Save Data" and give your profile a name.

This will create a new save file for your game, allowing you to have multiple profiles with different save files.

Important Note: Each profile will have its own save data, so you won't be able to transfer progress between them. You'll need to start a new game from the beginning for each profile.

Let me know if you have any other questions!
