So I downloaded a PSP game and it's the first time I've used a PSP emulator. I'm using PPSSPP. I extracted it using Winrar to my desktop and tried opening it using the emulator. It says that the file is compressed and that I need to decompress it. I tried extracting it using Winrar again to my Downloads folder, said the same thing. I then tried using 7-Zip and extracting it to one of my folders... I'm not very good at this, and have no idea what's going on. Any help would be much appreciated
