I bought a psp with 3.80 fw I know I cant put games on a memory stick if I have this version on my settings I saw a link that said update ver 2.00 if I do this does this mean my new fw will be 2.00

no because your in 3.80 if you want to do that download a downgrader from psp-hacks.com ------------------------------------------------------------------------------------------------------No because if you already have a higher version than the one it has, it wont let you; it will say something like: "your psp system version is 3.80. There is no need to update."
