I want to copy files from my 4gb sandisk ms to my sony 8gb sony mark 2. When I got custom firmware I had a few files and folders that I automaticly had on my ms. I included the attachment 1.bmp and 2.bmp showing files that I when I put custom firmware on my psp. 1.bmp is in the root of my memory stick and 2.bmp is showing files in the PSP folder in my memory stick. Can someone please tell me if I need to copy these files and folders and what the purpose of them are?
