PS2 Backups running on the PS3

Here is a short video of someone booting up a PS2 backup game on their PS3.

Note that this method actually requires you to open up your PS3 and void your warranty by soldering a 3-way switch to your Blu-Ray drive in your PS3. This is confirmed working on a Firmware 1.10 PS3 and confirmed not working on Firmware 1.31+.
