hay there let me help you by words
1. download Joil play fr om ps
2. Download the game "small on top" and extract it
3. After it is should have separate file name "small on top" (i recommend copy it to another folder so make it easier to access , for example I'm copy the file to "download" folder )
4. Open you're Joil play and press the {+} button
5. Game name ( you can add whatever you want)
6. Same story for Game version
7. {Impornat}For executable file -> choose -> screech for the folder you copy the "small on top" file (in my chase i copy it to "download" file ) -> after you found it keep pressing the file "small on top" file until you found a file name "Game.EXE" -> press chose -> ADD
8. Learning the Joil play mechanic need some time :D
