I tried to emulate psp games with jpcsp but now i know that firstly i need to decrypt the isos in my psp. I found a way to do this that is by using iso tool but i follow the instructions and i put it in the iso folder of the psp's memory card but when i open my psp, i can't find the application. Can someone suggest me exactly which folder to keep and where to keep and where to look for it in my psp. Thanks in advance.
