If you have full version of VGS Just create a new memory card or select any exisiting one.click edit---preferences---choose.Its very easy. 
Now dont tell me you are using a demo version and want to setup a memory card in it because you cant.
For using game shark codes you will need a cheating tool like pec or cep.You should get the necessary info on this site itself.Both are very easy to use but in PEC you dont even need to input the codes manually so it will be much easier for you.
