open the minecraft.jar (with WinRAR, WinZip, w/e)... locate and mark the following files and folders in it:
hit the extract button, or simply drag and drop them to ie. New Folder (name it Default TP, or w/e you want)
When you have done this = you have extracted the Default TP from the minecraft.jar = you have now a separate Default TP
All you neeed to do now is to get the Dinnerbone´s Resource Pack Converter, run it, select the extracted Default TP folder you just created and hit the Convert button to start...
When it is done you should get a new folder named "Default TP-1321654651564654" (it has the same name as the source folder from where you converted the TP but at the end are numbers...
After this you just simply rename the folder to w/e you want and drag and drop/copy-paste it into the /.minecraft/resourcepacks folder.
that´s it.
You don't need WinRAR or 7zip to get those files. Just copy and psate the .jar somewhere else, then open it with notepad (or notepad++ like me) and press "Save as" then select the type "*.*" and change ".jar" to ".zip". then you can just double click it to get the files. (Note: you cannot change it back into a .jar so make sure you did a copy unless you want to reinstall Minecraft. Also Note: Since you cannot change it into a .jar again without corrupting it, this will NOT work as a way of installign mods, I have tried)
It must be an .ogg file. There was an online .ogg generator/converter somewhere.. idk the link anymore..
