You want to access to server. Yay! You don't have the mods. Boo. Well, here are the up-to-date instructions on installed said mods. 1. Have 7zip or WinRar or WinZip or an unzipping software. 2. Navigate to C:\Users\YourWindowsProfileName\AppData\Roaming\.minecraft\bin 3. Make a clean install of your minecraft.jar. To do this delete the /bin folder, rerun minecraft, and it'll redownload it for you. 4. Make a backup of your new clean minecraft.jar. Copy it and rename it to something like minecraft_old100.jar or something. 5. Delete OLD CONFIG FILES. These are in your /.minecraft folder and have names like 'buildcraft', 'redpower', and 'config'. If you start your client BEFORE installing all the mods, your configs may conflict. Don't. IMPORTANT: To add files to the minecraft.jar, unzip the .jar with your unzipping software and add the files there. DELETE THE META-INF FOLDER. DELETING YOUR BIN FOLDER GIVES YOU A CLEAN .JAR. THIS IS IMPORTANT. -Step 1: Start with a *completely* fresh Minecraft. Delete, rename or move your existing .minecraft directory, then run the Minecraft launcher to get a new one. -Step 2: Using your favourite archive program, extract .minecraft/bin/minecraft.jar to an empty directory and delete the META-INF directory from the extracted files. Make a copy of the original minecraft.jar, in case something goes wrong. -Step 3: Download Modloader 1.2.5 (http://dl.dropbox.com/u/20629262/Latest/ModLoader.zip), Minecraft Forge 22.214.171.124 (http://www.mediafire.com/download.php?az7gz3couya357i) and CodeChickenCore 0.5.2 (http://www.chickenbones.craftsaddle.org/Files/CodeChicken/CodeChickenCore-Client 0.5.2.zip). Open the Modloader zip file and copy everything from there into the directory where you extracted Minecraft to, overwriting everything as necessary. Next, unzip Minecraft Forge and copy it into the extracted minecraft.jar directory, also overwriting everything. Finally, unzip CodeChickenCore and copy it across to the extracted minecraft.jar directory. It shouldn't need to overwrite anything. -Step 4: Again using your favourite archive program, compress all the files and folders in the extracted directory as a .zip file. Rename the resulting .zip file "minecraft.jar" and copy it into your .minecraft/bin/ directory, overwriting the existing one. -Step 5: Test it. Run Minecraft and see if anything dies horribly. If it works, continue. -Step 6: Download these: Iron Chests, version 126.96.36.199 http://www.mediafire.com/file/jd7do4esgd0ykg4/mod_ironchests-client-188.8.131.52.zip Compact Solars, version 184.108.40.206 http://www.mediafire.com/file/bzsf5i3hd68eyty/mod_compactsolars-client-220.127.116.11.zip Buildcraft, version 2.2.14 http://dl.dropbox.com/u/44760587/buildcraft/2.2.14/buildcraft-client-A-core-2.2.14.zip http://dl.dropbox.com/u/44760587/buildcraft/2.2.14/buildcraft-client-B-builders-2.2.14.zip http://dl.dropbox.com/u/44760587/buildcraft/2.2.14/buildcraft-client-B-energy-2.2.14.zip http://dl.dropbox.com/u/44760587/buildcraft/2.2.14/buildcraft-client-B-factory-2.2.14.zip http://dl.dropbox.com/u/44760587/buildcraft/2.2.14/buildcraft-client-B-transport-2.2.14.zip Wireless Redstone CBE, version 1.2.1 http://www.chickenbones.craftsaddle.org/Files/Wireless Redstone CBE/WR-CBE Core-Client 1.2.1.zip http://www.chickenbones.craftsaddle.org/Files/Wireless Redstone CBE/WR-CBE Addons-Client 1.2.1.zip http://www.chickenbones.craftsaddle.org/Files/Wireless Redstone CBE/WR-CBE RedPower-Client 18.104.22.168.zip Railcraft, version 5.2.4 http://dl.dropbox.com/u/38558957/Minecraft/Railcraft_Client_5.2.4.zip IndustrialCraft v1.95b CLIENT http://forum.industrial-craft.net/index.php?page=Thread&threadID=5896 IndustrialCraft-Buildcraft Crossover v1.28 CLIENT http://forum.industrial-craft.net/index.php?page=Thread&threadID=2444 Redpower 2 pr5b2 CLIENT (all of the client files) http://www.eloraam.com/?page_id=130 Copy all of these files to the .minecraft/mods/ directory. If you look at the log files, Iron Chests might complain about having an incorrect Forge minor version. This can safely be ignored. -Step 6: Download Advanced Machines v4.0 from http://forum.industrial-craft.net/index.php?page=Thread&threadID=4907 Open or extract the .zip file, then go into the client/mods/ directory inside it. Copy the AdvancedMachines_4.0_client.zip file into your .minecraft/mods/ directory along with all the other files above. Step 7: Download the block ID config files: http://www.bitupload.com/6lbo70qnp0qd (note: link might expire - tell me if it does). Unzip it directly into your .minecraft directory, overwriting anything in the config, buildcraft and redpower directories. You should now be ready to run SB Modded Minecraft. (old "guide" follows) OK, here's a guide to installing the mods which we'll (hopefully) be using on the SB server with Magic Launcher. Due to various bits of legal crap, I can't make a one-click installer, nor can I put all the mods in one file for download - this is also why some of the files are direct links and others have to go through someone else's website (again, sorry about that). You'll have to download everything manually, but the installation process is a lot simpler than it used to be. You don't need to use this procedure. If you're happy with installing mods the traditional way, scroll down to the bottom of the post to see the list of what's in use here. EDIT (2012-05-26, 1112 GMT): -changed Railcraft download to version 5.2.4) -If you have already followed this guide, delete the existing "Railcraft_Client_xxx.zip" from your Mods directory and then download the new version (the link is updated in the tutorial, we're using version 5.2.4 now). Load up Magic Launcher, click "Setup" and then click "Manage" in the bottom-right of the Setup window. Delete the existing "Railcraft_Client_xxx.zip" file from the window that pops up, then copy into there the "Railcraft_Client_5.2.4.zip" file which you just downloaded.
