download ESR and follow it's readme. it can be launched from uLE when uLE is booted from FCMB. once you got that, you can play backups on your ps2. also, you may want to consider getting a network adapter so you can use an internal hard drive in your ps2 so you can play games off of that via a program called HDLoader. Loading times will be shorter, and it will extend the life of your laser by not using it.
If you need help, post a question in the
forums, not my PM inbox. Thank you.
