1. rip it with either dvd decrypter, or IMGBurn. This ensures you get both layers of the disc.
2. Patch the ISO with Toxic Dual Layer patcher.
3. Patch the ISO with ESR Patcher.
4. Burn the ISO to a dual layer disc at 50% maximum disc speed. (be sure to use quality media such as Sony, Taiyo Yuden, Verbatim, or some other top shelf media according to this link.
that's all there really is to it on dual layer games.
