so now he is considered dead in the forums
so go to the irc for **** u need to tell him

Ya I am.. I thought maybe it would still work as it doesnt affect anything new but maybe it does.

Great stuff. But I wonder, why dont you also give links to the older versions of stuff like modloader and audiomod? The reason is, there are some kick ass mods for minecraft but their makers are too lazy or cant make their mods for the newest versions of minecraft. Minecraft its self can be downgraded for the mods to work, but those mods also need the older versions of modloader and audiomod and etc to work further more.

Did you copy over the folder as well as the class files?

Quote from Scorpius1981

That won't work, mods only work on the specific version of minecraft they are created for, since each version of minecraft including the snapshots are completely different from each other, as far as the code is concerned.

Look in the OP for links to old versions. Right next to the links for the current version.

Quote from UnseenB4

What's up people.

As you might be aware... I'm new here.

So, I thought I would ask. Does this mod work on a Multiplayer Server? Seeing as I have one, but I am trying to install it for online use, but I don't think it would work, solely based on the fact that it is telling me to edit "minecraft.jar" and not "minecraftserver.jar". Or is it pretty much the same file?

Thanks, any help would be much appreciated.

No, it's for single player only, not multiplayer. Look for modloaderMP.

You can, in the links for the download for the mod, the last link is always old versions.

dear risugami I can't instal modloader on my mac I deleated my meta-INF folder What else can i do sincerily ronnnie76

For biospheres is there a end dimension for a biome because I know there is for the nether.

Does anyone know if there's a way to force Biospheres to make a solid bedrock bottom? I don't like having a Void underneath me. I can't build on it after getting stuff from all the spheres.

ModLoader is the stupidest mod i ever heard of

it is a core program of most mods

Quote from GhastLover

try mcedit

MCedit says it's for 1.81 beta. I'm running 1.1 so I need a solution that works for 1.1

I installed Biospheres using ModLoader, and when I clicked single player...

Thanks for the great mod! It really helped me make mine.

Despite multiple attempts, I cannot update Minecraft 1.1 with ModLoader. I tried applying the ModLoaderMP along with it and it still freezes on Mojang title then quits to desktop. What gives? Is the OP link broken?

Whoops, so sorry, didn't see that link. Thanks a lot!

Hi...so i've been lurking this section after my last post 2 weeks ago about this error:

I also saw some of the posts which have the same problem as mine.. and all we can get was DELETE META-INF Folder or CLEAR MODS FOLDER.


I did all of the other suggestions as well..
Still can't get it to work.

Here are some of what I tried to do:

1) When I install ModLoader using MCPatcher. It doesnt work(take note I used a fresh 1.1 jar and no MODS Folder yet). I tested the game first in MCPatcher and got the error ABOVE ^ .
I tried running the game and I get a black screen before the Mojang Logo but after the loading of files.

2)When I install ModLoader manually. same situation as above,black screen.Fresh .jar.

3)When I install ModLoaderMP both manually and using MCPatcher(different instances and no mods installed yet). The game starts well. No errors.

4)When I add ModLoader to the ModLoaderMP installed Jar....i get the same thing as number 1.


I want to use ModLoader for Better Than Buildcraft mod. Please help me. :sad.gif:

does the spawner gui work for multiplayer
