4 gig memory stick
To my knowledge you don't want to use a 4 gig mem stick to make a magic battery here is part of the readme file
A spare Memory Stick Pro Duo of less than 4Gb. (256Mb should be
enough for all applications)
I used a Sony 256, it works great you can get a 512 at gamestop for like $10 bucks too
