To find a Wii pin code that you have set up you need to access parental controls. To do this you firstly need to access the Wii System settings. This is achieved by clicking on the blue arrow; this takes you to the Will System settings menu options. Choose "Parental Controls" and select Yes. You will now be prompted to enter the PIN. If you have forgotten the PIN code, there is an option to click on "I forgot". This will then ask you for a secret answer to a memorable question. The secret answer would have been submitted when you first set up the Wii Parental Control options. The answer you put into this field is case-sensitive so make sure you enter this correctly. Once you have entered the answer you can adjust both the highest game rating allowed on the Wii, and the PIN. When you have adjusted the PIN, you will be prompted to enter another secret answer to a memorable question. Most people opt for the mother's maiden name, or the name of their first pet, as this is the easiest to remember. The default setting for PIN codes for Wii is normally 0000, this is if you have not yet set one up. To find a Wii pin code for a particular game (to allow you access to the game) you need to go into the settings of the particular game you are playing. Most games have a pin code to stop people who have not yet reached the recommended age for a game from playing the game. When you have acccessed the particular game you need to click on the message screen and then you find all the personal information that was stored at the time of setting the game up.
