yay! people are actually using my unpacker! 

*sigh*...if you would've read the readme, you would've known that you can use it via command line arguments....

Woah, how helpful. Try not to be so rude next time.

"Attention! Please read the README, because the command line arguments used to pack/unpack have changed!"
this is written a few lines under the download link on my blog. it's highlighted.

"For usage, please check the README in the archive."
same. directly above the download link.

yeah.

Uhhh, the unpacker closes itself right after I open it...

*sigh*...if you would've read the readme, you would've known that you can use it via command line arguments....

So... Could this be used to rip the character sprites from the game, edit them, and then put the modified sprites back into the game?

As of now, no, you can't. I need to document the palette files better, before I write the code. I can unpack palettes containing a single sprite, but I've yet to successfully unpack one with multiple sprites inside.

I wonder if you could find the story mode levels to open in devmode to remix the levels and stuff.

sure. they're 1-1, 1-2, 1-3...and so on....

But I guess there's always a moral dilemma when releasing a tool that may enable people to cheat...thing is, it's all about the players. cause if people want to cheat, they'll cheat regardless. I hope this won't ruin the game, but it's kinda funny to watch the intro cinema for "teh internets" :)

With this you could play bosses with other characters, change the kids warp zone levels to the first three, and cheat at chapters you are stuck on... this could also be used to cheat on leader boards (make a really simple level in devmode and make it open that) "With great power comes great responsibility"

Yes, I agree. Cheating isn't cool. The whole point of the game is to get through the levels presented to you. So please, don't cheat on the leader boards, cause that just makes you lame and sad.
And also ruins a really awesome game for everyone.

I just hope you realize, I wasn't planning to cheat, I just wanted to point out that if this gets into the wrong hands...
On a brighter note you could use this to make a "super meat boy 2" and make your own chapters with dark world levels... but then again that would interfere with the leader boards.

Yes, I know :) I wasn't suggesting you were going to cheat :) Just like I'm not going to cheat with this. When I hacked the Forest, I turned off Steam, just to be sure I don't break something :) but other people might think about it. It was sort of a message to them :)

And I'm not quite sure about interfering with the leader boards. When I did the SOD hack, the levels showed up as not completed in the Forest. I think the leader boards might be locked to certain levels with a range of id's...not sure though...

'Till I have some time for that, here are the basic steps. Remember, back up your files before you do this!

there are some .chapter files in the "levels" folder. there's "Forest.chapter" and "SewersOfDross.chapter".

these are basically .txt files with .chapter extensions.

each contain a list of all the levels in the respective chapter.

you can open both with notepad and replace the "1-1", "1-2" and so in Forest.chapter on with "g1", "g2" and so on, just like in SewersOfDross.chapter.

also, at the beginning of .chapter files, there are some basic chapter properties. If you compare them, you'll notice SewersOfDross has an extra line that locks the character to gish (headcrab or gooball in PC versions). you can basically copy paste that line in Forest.chapter.

Now, the character will be locked to the sticky character. I'm sure you can look up  goo balls' ID on the forums/interwebs :)

Save Forest.chapter and pack the datafiles, and it should work.

When I did this, switching to the dark world crashed my game, so I don't recommend you do that   

Man I would love to be able to play sewers of dross on PC with Goo in the fashion u described but sadly I fail with such things as "hacking". Either way nice job with the unpacker. Well done sir.

I'll make a tutorial as soon as I log onto windows. currently have some stuff to finish on mac :)

One strange problem.
Some of the sound files crash my PC. Might be me, might be them

hmm...strange...I went through and played all the sounds as part of my original testing of the unpacker and nothing went wrong...

also, I'd like to point out that all the levels in the xbla "teh internets" are present in gamedata.dat. I hacked my gamedata a bit and switched the levels in the Forest with the one from The Sewers of Dross.

Can you play it with goo ball?

sure. there's a character lock line in the chapter definition files. you can set the character id to the goo ball:)

well, you can't change the characters for xbox ones, because the behaviour is hardcoded. but you can change their appearance

Ah thanks, i see, i needed to create a batch with the arguments. 

I, for one, made a batch for each argument, so I don't have to open a console window and write the same thing over and over again....   

yeah, how the shit do i use this. Ive got gameaudio.dat and the exe file in the same folder. How do i do dis

command line arguments are listed in the readme

yeah but how do i change them and what do i do them in.
I dont usually work with this kind of stuff

well, for example, you could create a batch file. open notepad, write "smb_unpck.exe unpackSnd gameaudio.dat", without quotes, save it with the extension .bat next to the exe and double click on it. a console window should show up.
