here download this and it will create the magic memory stick for u click on the begin.bat or start i forgot what is says

this will take u back to 1.50-http://www.megaupload.com/?d=EMBPKIOU

and this one will take u to 3.80m33 use whichever u like

thanks for the advice,so i have downloaded the 1.50 downgrader(is this the magic memory stick?) and the 3.80m33,what next..lol..told you i was'nt the brightest..did i only need to download 2 items? what im lookin for in the end is that my son can play psp games im not really after the emulators(i think)

sorry, but talking about isos or csos (compresed isos) is not allowed in this forums

ok..how do i play my back-up games....where exactly do i put them on the memory stick??

I would recommend updating to the latest custom firmware before trying to play your backups

go to the firmware update icon on ur psp and i think it will update ur psp to the latest custom firmware the latest is 5.00m33-6

after youve done that format your memory stick so it can organize all the folders for you

you will know where to place ur iso cso's after that
