Ok so I have the current CFW 3 what ever and have played games this whole time. Now i recently got a back up but it was not a iso or cso. When unzipped (the rar) it has a folder labeled PSP_Game and then a UMD_Data file then inside the psp game folder it has sys dir/ usr dir and a bunch of files. In sys dir or usr has eboot , etc. And all those files. I tried renaming the top folder to a short name and dumped onto the psp but it doesnt show up. What do i have to do?
