Does anybody know of a way to get PSX Emulator for iPhone 4s w/ out jailbreak?

Does anybody know of a way to get PSX Emulator for iPhone 4s (iOS 7) w/ out jailbreak? Im trying to relive my childhood on my phone. I have the gameboy emulator and i know the date and time rule. I was just wondering if anybody knew a good place to get a psx emulator without having to jailbreak my device.

Also, does anybody on the off chance know a record-your-screen program for iOS 7 without a jailbreak? That would be much appreciated.

Thank you in advanced,
