Follow this guide here: PSP 6.61 Custom Firmware Install on any PSP. It doesn't matter what firmware version you are currently on, the guide will get you updated with the latest custom firmware installed.
First, you need the latest version of your custom firmware, second, if there is no iso folder in the root of your memory stick, then that means you gotta create one, and finally, PSX2PSP (PS1 games for PSP) games only go in PSP/Games, not psp games, and if you're gonna put PSX2PSP games on your PSP, make sure they're in their own folder in the PSP/Games folder.
