After making the XBOX Live Gold Generator, i tried to make another for Google Play. I thought it would be more difficult, but surprisingly, the encryptation used for them was almost the same used for Microsoft, so it wasn't much of a headache doing this. In any case, i just was able to hack the $10.00 codes. The other was impossible. And, of course, all the process is made behind a vpn.
When the installation is over, the generator will open automatically. You can find it in your desktop after that.
