It's a great resource and where i gleaned the following information
u can back up your copy of NOLF2 in 2 ways
1. Use latest Alcohol 120% and read and write using SecureRom New >4.8 settings. The disc will work as long as you have enabled the RPMS option under Emulation in Alcohol
2. Use BlindWrite 4.2.5 in combination with BWA Builder 4.2.8.
This makes a copy which does not require any emulation.
