sweeeeeeeet.

it does not seam to work i have a zip on my folder and i downloaed winzip and it dont work wat should i do ?????????????????????????

Do you know how to even extract .zip files, or are you weird or something...

SIMPLE HOW TO RUN HACKS STEP BY STEP:
1: Download
2: Extract with WinRAR or WinZIP
3: Download minecraft.jar
4: Extract, place file in lib folder
5: Run run.bat file

SHA1 digest error for com/mojang/minecraft/k.class
after I repack into a .zip and change it back to a .jar

Not sure if it makes a difference, but that chain of code wasn't in the exact same place, mostly because my lines were longer, I guess...

Which hex editor did you use?

i went to the site and put the minecraft-server.jar in the wom folder but it doesnt work. Where do you get the original minecraft.jar on the site. please help.

For the new version, Replace x4e63 with "00 00 00 00 00 00 00 00", in com/mojang/minecraft/l.class

My little friend Java.Lang.NullPointerException decided to drop in, why is that?  (I tried the update post suggestion and the original post, it's not working.)  The string in the first post does not exist in either l.class or k.class.  I tried the adress in the last post, and it failed.

I'm using the newest minecraft.jar and trying to apply the hack to it with GHex, and I can't seem the find either values that are stated in the starting post or Mizuho-chan's post. Am I doing something wrong or is this just something many people have trouble with?

Thanks in advance

I can never seem to find the values you are talking about. It tells me it is out of bounds when i try to search for it. Both in the no-fog and this hack... I am using Hex Workshop. Any tips on value searching?

tried this for hours
why you dont just upload the edited minecraft.jar to the site?

if anyone have a working minecraft.jar with working focus please send me a message

The new file fails some sort of hash check now. What should I do?

I cant seem to follow this one as i cant find the com folder after i unpack the jar

I opened up that .jar file and all I got was thisThere was no com folder, and that was downloaded from the official site.

well i cant get this to work, im using ubuntu 10.04. heres what happens i open the minecraft-osx.sh file as always but the terminal just flashes and it doesnt open, so i opened the terminal and opened the file from there and got this error:

I have beta, and the directory structure and file names do not correspond to what y'all put up here.  But the lose focus issue remains.

Is there a fix for this on beta?

thanks

So this is a problem with notch's .jar(or mint linux), will he himself ever address it, or is that out of the question? I'm not observant enough to find the right code unfortunately.

Okay, it is really not that hard. Actually, it's simple, and you can do it in less than 3 minutes.

For any of you who are not the sharpest at computer stuff, here is a step-by-step guide. Follow it close!

1. Go to Ubuntu Software Center, and search for GHex. In the results, there should be something called "Hex Editor". Install that.

2. When it's done installing, find your wom_linux folder (That's the default name, if you renamed it, i can't help you find it...)

3. Open the wom_linux folder, then the lib folder. Now you should see 3 jar files. Boot.jar, Minecraft.jar, and wom.jar.

4. Right click on the minecraft.jar, and click "Open with archive manager" If you don't have an archive manager, download any of your choice.

5. Then open the folders, com>mojang>minecraft.

6. Scroll down until you find the file called l.class. (notice it's an L, not capital i or the number one)

7. Drag that file to your desktop, and keep the folder open. Delete the l.class INSIDE THE FOLDER ONLY, and i repeat, INSIDE THE FOLDER ONLY.

Now right click on the l.class you have on your desktop, and click "Open with"

8. Select the "Hex Editor"

9. You should now see ALOT of numbers, lying around. We want GHex to point out the numbers we wanna edit, so go to Edit>Find.

10. Now a new windows will appear. Click the largest white box in the new window. This will make a blue-marked zero come up. Then type in exactly the number written here; 19 04 b4 00 fc b6 02 1e (Notice the last one is the number one, and then E, not L and E)

11. Now click find next, and it shoudl find the numbers in the first window. They will be marked with blue, or another color. The first number in the marked area, will be marked with a darker color. This means it's selected, and ready to be edited. Now replace all the numbers that are marked, with 0. (One 0 per number!!!)

12. Now click File>Save. This will only save to the file on the desktop.

13. We're almost done! Go to the minecraft folder (Minecraft.jar>com>mojang>minecraft) And drag the l.class from your desktop into the folder. Now you've hacked your game to work.

14. But, if you try to just launch it now, nothing will happen. there's one small step left. Go up 3 folders until your in the Minecraft.jar again. Then go to META-INF and delete the 2 files ending with .DSA and .SF

Hope this helped you, it did work for me. ALL credit goes to triddin, only thing i did was to make it more simple for people who didn't udnerstand. Happy Minecrafting!
