Hello NGU!
I'm going to show you how to add a custom texture pack & skin!!! A jailbroken PS3 is required. STEPS:

1) Download Link:You must login or register to view this content.

2) Open up FTP Server and go to minecraft (NPUB31419) and find \NPUB31419\USRDIR\Common\res\TitleUpdate\res adn replace the terrain.pngs with the ones you got in the download link, and you now have the texture pack [Sphax]

3) Goto \NPUB31419\USRDIR\Common\res\mob and replace a character you wont miss with the custom skin and online you download will work as well. You can also replace the zombie etc...

4) Thats it! You now have a fully working custom texture pack [Sphax] and Custom skin [Made by me]
