Never hurts to up ones knowledge!
But yea not gonna lie. The actual modding process is kinda advanced. The best thing to do is go on craiglist and find a local modder and just pay him to do it for u. I found one that lives about 15 mins from me. He charged me 50 for the inital flash and then every update is only 15$(Hasn't been a update since last year though!)
I do know the firmware will be updated soon though(IE and whatnot) Wether we will need a new modded firmware at that time or not we won't know til it actually comes out.
Now the burning process is simple as buying dvd+dl discs and using imgburn to burn the iso. The only tricky part is you need a certain type of burner flashed with a certain firmware to make 100% undectable backups. The actual burner itself is only 20$ and you just download the update to flash it.
There is a work around though(Which i use myself just cause im too lazy to switch out my dvd burner) Which relies on you installing the game to your harddrive.
