4GB memory stick PRO duo?
SO im plannin on buying one for ISO storage, will it work with ISOS, and when i get it, do i just insert it into psp and format, and it will be in CFW file format, or do i have to copy folders from my other memory stick manually, and delete and add stuff i want, i know that the prx plugins will be gone once i insert new memory stick and all the crap from it will be too, but if i format will it add the folders such as GAME and GAME150 and GAME 380 and seplugins and such, thx in advance!
