PlayStation 2 Software Compatibility Now Available for All PS3 Models

by ps3iso on August 6, 2012

In other news: Cobra-USB dongles are no longer required to play PlayStation 2 retail discs on your PlayStation 3 thanks to developers mysis and eussNL. What’s even better is this modification does not discriminate — all PlayStation 3 models are fully supported!

The only requirement is that your PlayStation 3 must be running firmware version 3.55.

Note: This will not run PlayStation 2 backups. It is the same buggy emulator Sony introduced in firmware update 2.60.

Getting Playstation 2 Software Emulator working

Method (on Firmware 3.55, without! Cobra-USB Dongle or Downgrade) for all consoles (fat & slim).

2. Get into Factory Service Mode (FSM Tool/Dongle)
