HOWTO: Making empty password in j2l :] !Works!

[SzymekRak]

Found it there:http://pl.youtube.com/watch?v=z8gjyjt3E-4&feature=related
Who don't want to watch the video:
0.Make backup of level
1.Open that level in hex editor.
2.There should be "LEVL" string somewhere in up of the file.
3.Modify the four bytes after "LEVL" to 00
4.Save
5.Open level in jcs
6.Password leave empty.
Have fun :]

Easy peasy, you don't even need a hex editor to do this. Just leave the password in JCS itself empty.

[blurredd]

There's also removing the password entirely. Though in general, most people just use a version of JCS that ignores passwords.

What I mean to say is if someone is going to circumvent a password, that's the method they are most likely to use. I highly doubt most people hex-edit passworded levels or even considered it, but I could be wrong.

I would probably have done this if I ever needed to "crack" a level

[Cpp]

I use the passwordless JCS's all the time.

this doesn't work for me, when i hit save, it says:

error writing:
ML_qob.j2l
Error 5: File access denied

any help?

1.File may have read-only attribute
2.Close jcs
3.Close jazz
4.May work

[Thedboy]

thanks for your help, but the same thing is still happening. it is not a read only file.

I had no problems doing it, make sure you dont change the Levl numbers, but the 4 after those

LOL this second level is the weirdest hotel I've ever seen :rolleyes:

Anyway, nice find.

thanks again, but it still doesn't work. it works fine for some levels, but not others. i think it is probably something to do with the file itself, as opposed to the program

Hmm, if you send a private message to me with your email i'll send ML_qob to you

Try to make copy of the level for example ml_qob123. If it doesn't work, I send to you via PM my ml_qob.j2l with empty password.

uhm... i did already :-)

yeah i've already got one with an empty password, but thanks for the offer :-)

3.Modify the four bytes after "LEVL" to 00For the record, it's three bytes, not four. The fourth byte tells jj2 whether or not to appear in the home cooked level list. You can find out more about the J2L file structure in this thread (http://www.jazz2online.com/jcf/showthread.php?t=15059).

[Jerrythabest]

What is the actual difference in the file between an empty password and no password set?

[cooba]

The same as between "0" and "NULL".

[Cpp]

Now he's gonna ask for the difference between those two. ;)

Technically an empty password still returns a hash value (0), which makes JCS believe that the level is still passworded. JCS uses a special hash constant that is equal to NULL. Whatever password results in this hash will be considered empty and the password box will no longer appear. Neobeo managed to list a few such passwords here (http://www.jazz2online.com/jcf/showpost.php?p=376663&postcount=92).

[Jerrythabest]

But then, what's the hash (in the file) of a depassworded level? If 00 00 00 is still considered a hash of a password (an empty password), then what's in these three bytes if you depassword the level.

Or just put really clear: what's the hash of 'oesmonk' and all these other funny things?

[IJskonIJn]

When a level has no password (and no password box) the code is 00 BA BE.
But don't i have any idea why oesmonk works

[Cpp]

When a level has no password (and no password box) the code is 00 BA BE.That's the correct hash.

But don't i have any idea why oesmonk worksBecause CRC32("oesmonk") == AD 00 BA BE. The first byte is discarded.

[Jerrythabest]

yay now I can make my own password removal password finder to get my own password removal password with my name in it :D:D:D

Still, it's funny that it's not just 00 00 00.

[Slaz]

lol I still remember the pretty 'over excited' news message on Jazz2City that Epic was going to release JJ2 1.23 with password functionality for your levels.. Thinking about that under reading this topic makes me gonna laugh.. :p

[IJskonIJn]

why should you even password your levels?

[Nonomu198]

so no one could find the SECRET ULRTA hotel events you use.
