Hello all, In the past there have been a few Threads about unknown Brawl files, but most of them are long forgotten and died out before things could really be finished. Alot of information was discovered in those threads, but sadly there isn't one central point to keep this information, or to continue research. So, that's where this thread comes in. While most of brawl's files have been parsed and are now editable, i feel there is still potential in the files that remain mostly un-touched.One of the mostly untouched areas in Brawl modding is SSE. Some files have been partially decoded as of now, but with full knowledge over the files, we may be able to write a completely new SSE. From that, someone would be able to write a tool to edit the files. That's just one possibility of uncovering the unknown files, just think of the other files that are still unknown.

This thread is going to serve as a place for people to help with parsing Brawl files and figuring out exactly what they do. I'll post some of the information from the previous threads here as well to try and keep everything centralized. Hence why this post will borrow almost copy paste from previous threads. Thank you to all who helped uncover these files and wrote these out.

Intro to Hexing

For those completely new to hexing, let's do a quick little exercise. Open Brawlbox, select File --> New --> BRRES. Right-Click the BRRES and select New --> Character Animation. Finally, Right-Click the animation and create a new bone animation. You should end up with this:

Now you should have a basic animation file, 1 frame without any animation data. Right-Click and export the NEWCHR animation (CHR0) so it can be hexed. Open up the animation CHR0 in your hex editor, any hex editor will work, I'll be using Notepad++ but the results will be the same. Assuming you didn't rename the CHR0, it should look more or less like this, depending on your view settings:

So you might be thinking "i could never read what these random numbers mean!" but let's get into that right now. Since there aren't any animations in this file, it's pretty much empty. Open the animation in Brawlbox and change the Translation X keyframe value to 1, export the CHR0 and open it in hex again.

You can see some changes here and there, but how do we find out what they mean? Thanks to Brawlbox, we know that this animation file has a single keyframe with a value of 1. That number (keyframe value, not amount of keyframes) was translated into a 8-digit value called a Float value, which can be translated with this webpage. Tools like these are a hexer's best friend.

Using that webpage, you can see that 1.0 in hexidecimal is 3F 80 00 00. You should be able to find that number in your hex editor: if not, then It's highlighted in the previous image. Any single number, even 99999 or 3.14, will be displayed as an 8-digit float value. If you change the keyframe value in Brawlbox, then the only difference will be that float value: everything else remains the same.

Now let's do something cool with your hex editor: Click on the beginning of the float value and type 44 a7 20 00, save and open in Brawlbox. You just hexed the keyframe value from 1 to 1337. Pretty neat, right?

This is what Brawl hackers do to change simple number values that aren't editable in Brawlbox, as well as hacking computer files in general. Try using your new knowledge of float values and hexing to change numbers in other Brawl files, or add more keyframes with numbers and see where each number ends up.

In the meantime, I'll set up the next tutorial about identifying file structures.
