JRE compares the checksums from the files in META-INF, with the other files in the jar.
If the checksums doesnt match then the game wont work, so always delete META-INF if you want mods
Umm... I installed the More Worlds v2, did all you said perfectly. All I get is a crash report.
Minecraft has crashed!

Can you please help me???
Missing class file. DID YOU INSTALL MODLOADER?
EDIT: also remove META-INF
go learn some java. because making a SIMPLE block is very easy. also decompile other's mods to see how they work
i tried and i did what people said and i got errors just cuz i named it itemLantern and the rest was the same as they said.. just all said lantern. that was for an item but still. and this wouldnt just really be for me but for lots of people.. would be really usefull instead of everyone going to buy books or watch utube all day and learn java and make them.. a simple program would take maybe minets and easy to understand.
public class helloworld()
{
public int main(string[] args)
{
System.out.println("Hello World!");
}
}
Erm... lets say i own the word hi. I SUE EVERYONE WHO SAYS HI. Seriously, this is what happens between Bethesda and Mojang. NONE OF THEESE OWNS THE WORD SCROLLS. Microsoft should sue Bethesda for using Scrolls, because theres something named A Scroll, More Scrolls. lolfail Bethesda. Mojang won. the end.
Before, in 1.4 or 1.5, there was a mod named MoveBlocks which could move chests, with items inside, and it didnt reset the chest, so the calculations will not be complicated.

=D I hope it works.
Also if it doesn't work then try to decompile an another mod that adds blocks and uses Modloader :smile.gif:
0
public mod_urmod() { ModLoader.RegisterBlock(myBlock); ModLoader.AddName(myBlock, "My Block Tooltip"); }?

You Cannot add new blocks to multiplayer. but you can make runes and make blocks HAVE some new features.
