Read how to boot Playstation 2 backups with your BLu-ray Playstation 3 drive. Maybe you can get that too old games to run again.
OK, I wanted a fairly easy way to play my PS2 backups on my PS3. I have read that you can do it by taking apart your PS3 and cutting a hole in the top and yadayada. Leaving the top off of my PS3 to play PS2 backups didn't sound attractive to me. So i searched around and found a forum for PS2 talking
about a tray switch for the fat PS2's back in the day. So i
did some brainstorming and figured it might work. I went to
Radio shack and purchased a 3 way toggle switch for $5. I
highly recommend 3 way. At radio shack it was called a middle off switch. That way your drive motor is not constantly running.
I came home and soldered the wires to the switch.
A note before we start. This is a fairly easy process, the most trouble i had was trying to figure out where to put the switch. there is no room to work with. I ended up taking out my card reader on my PS3 because i never use it and just mounted the switch there. You could possibly let it hang out. It's up to you. Just remember that if you plan to retain original functionality as far as the drive sensor and automatic load/unload motor, you will need 2 additional small on/off switches.
