I have the NEC 3540A DVD-RW, I installed the latest modded 'Liggy' firmware to it but I don't know what it does...Anyone know?
Then why did you install it?Just check Liggy & Dee's site again, all info is there.
Usually it improves burning quality and media support, also removes regioncode protection.
I actually wanted to see if I could copy 1:1 games with it...
This probably won't be changed by any firmware as it's usually hardware dependant.
