This is what Minecraft does when I launch it:

1) Displays log in screen. I can log in.

2) Proceeds through the 'setting up Minecraft Forge' form, and appears to complete all steps without a problem.

3) Displays a black screen.

4) Displays the Mojang logo.

5) Displays another black screen, which appears to last indefinitely.

 

These are the steps I am using to install (using the recommended version and the 7Zip utility to extract files):

1) Downloaded the file from here: http://www.minecraftforge.net/forum/index.php/topic,5.0.html Direct Universal Recommended.

2) Opened both that file and the minecraft.jar in 7Zip.

3) Dragged all the files across from that file into Minecraft.jar and confirmed I Wish to copy them.

4) Deleted META-INF.

5) Closed the Minecraft.jar and ran Minecraft.

 

The game does not go to any crash screen, however here is Command Prompt output. First, I have the output for launching the game without Minecraft Forge (and exiting normally), followed by the output with Minecraft Forge enabled.

Edit#1: I have not modified the Minecraft /bin/ in any way except installing Minecraft Forge as I stated above. I have attempted this installation 3 times following the instructions above. I have tried installing without removing META-INF as well. Operating system information:

 

http://i54.photobucket.com/albums/g81/azoundria/osversion_zpsb2aabdfa.gif[/img]

(Do not know why Windows doesn't let me copy this as text.)

 

Edit#2: Figured it out. I had left some files in the /mods/ folder, from before, which worked with modloader fine and were causing an issue with Minecraft Forge. Upon renaming the /mods/ folder it appears to launch successfully. It would be cool if Minecraft Forge was smart enough to discard outdated mods, or display a relevant error.

It looked like TechBrew with it's JourneyMap was trying to hook a keyboard resource incorrectly.

 

The problem with detecting 'outdated' mods is that it's hard to do. You would have to force the mod maker to tag the mod against the Forge version somehow. There's no real Java way to tell what version of Forge it was compiled against, which is good because it doesn't force unneccessary version compliance. On top of that, some mods still work even while outdated, so some players would like to load them if they still work.

 

The easiest way to tell if a mod is incompatible is to wait for it to do something bad, then crash out with a log dump. Which is already exactly what happens.
