Make a new thread and post your logs (in spoiler tags) there.

1. That's not the complete log. 2. Use spoiler tags next time!

Your launcher doesn't support Forge. Use an other one or the original from Mojang. Mod edit: If you're using mineshafter, then freaking buy the game.

Update your java.

Seems like you missed some files from Forge during installing it. Get a new minecraft.jar, download the latest universal Forge again and install it correctly!

No logs, no help. Post the content of the ForgeModLoader-client-0.log here in spoiler tags!

Forge 7.7.0 is for Minecraft 1.5, NOT for 1.4.7. Look here for a 1.4.7 version: http://files.minecraftforge.net/

That's not the complete log. Also use spoiler tags next time!

Which revision of Forge do you have? (7.7.0.xxx) Anyway, did you delete the MOJANG files within the META_INF before attempting to install Forge? How do you install Forge? Sorry, but since you have no logs, I need every detail.

Which Forge version? Which Minecraft version? There should be a log. The ForgeModLoader-client-0.log in your .minecraft folder. Did you delete the MOJANG files within the META_INF before you installed Forge?

Where's your proxy? Also AddRenderer doesn't get called. You have to register your stuff through RenderingRegistry. And for that you'll need to use a proxy, since you cannot use the RenderingRegistry on a server. Look here on how to use the Proxy system: http://www.minecraftforge.net/wiki/Basic_Modding Then look at the RenderingRegistry class or look in the wiki on how to register your renderer.

If you use eclipse, then you can simply make a search/replace.

.setUnlocalizedName for both, Blocks and Items, is what you're looking for. Also remove par2 from the constructor and the line with the blockIndexInTexture.

update NEI and CodeChickenCore.

You're sure you use the latest version? If yes, then report this to the NEI thread. I may suggest that you change the file extension to .zip and see if that works.

Yup

Is there any meaning to this? I don't quite understand... The problem is that Rei's minimap if it starts, it is. Zip, but the NEI no, that is. Jar .... HELPP! So? Put the NEI JAR in the coremods folder, since it's a coremod. Be sure you have CodeChickenCore installed, too or it won't work!

Well, the only thing you could do is to make your mod as a core mod. But don't ask me how, since I never made such a mod before.

cpw.mods.fml.common.LoaderException: java.lang.ClassNotFoundException: colossali.SHIM.common.ironmanmod Mod issue, nothing to do with Forge. Go to the mod's thread and report it there.

Where do you test it? in Eclipse, or in your mod zip/jar?

Do you want to let your entity push / block the Player like in the old versions of Minecraft? If yes, you would have to edit the EntityPlayer class. You can do that directly and risk incompatibilities with many other mods (which is bad), or you make your mod as a coremod.

Clean your lib folder inside your .minecraft directory and try again.

Forge wont work with tale of kingdoms, miniblocks, or any other mod I have tried. I have the updated 1.5 TMI. The old TMI worked fine with my old Forge with the 1.4.7 Minecraft. I am getting really frustrated. I don't know code, I am just a user. I don't know what runtime-deobf means. I said stop using TMI, since it can't handle that new feature. Runtime-Deobf is a feature of Forge which allows mods to keep working even if Minecraft updates. It "changes" the names of classes and fields / methods, so for example the Block class isn't named like aou, but Block. Use NEI instead, it has the same and some more functionality and it doesn't go into the minecraft.jar, which is good.
