Vielen Dank, the modded version you uploaded works
Well, it boots up at least, I don't see a different texture pack (the transparency is messed up though) ...
But now I can edit the png files again, I missed that so much, it was so easy before the TUs started replacing texture files.
In your tutorial you are replacing something in the DLC folder, but I can just edit the terrain.png in the res folder and those terrain files apply to the default textures of minecraft ...
So bassically I just had to patch the default.xexp from the TU to the default.xex of the game and copy the new files over to the Minecraft root folder. (I used your pre-modded version to save me some work though )
And then I could start using an image editor to edit all the png files ... I haven't had to use anything related to the files from the DLC folder.
^ Have I misunderstood something or are some of the steps from your tutorial optional?
I think it's nearly impossible to put Texturepacks in DLCs at the moment, they are stored inside of LIVE containers and as far as I know rehashing and resigning those isn't as easy as it is with CON containers.
