Now, connect your PSP Usb Cable to your PC. On your ms0: /  ef0: , Open the seplugins folder (If the seplugins folder doesn't exist on your root of your Memory stick, you need to create one. Rename the folder as a "Seplugins"). Now, Paste all of the psplink file into the Seplugins folder. Create a new 2 "Text Document" and rename it as "vsh.txt" and "game.txt". Now open both text document and paste this code :
