My English isn´t so good so I will keep this post small 
In a Videodescription somebody have written that he used the "Minecraft Extendet" Mod
I didn´t no what this Mod does so I research it.
I don´t unterstand much about Mod Developing but I think this Mod add more Block Ids and Terrain Sprites to the game.
And in this Forum I read multiple times that Alblaka can´t at the Sugestion because he need more Block Ids.
I hope I unterstand the Mod Descrition right 
Oh and here is a link to the Mod: http://www.minecraftforum.net/…extended-higher-blockids/
