noclip.website VS CyberChef

I know this is definitely not what you’re talking about because it’s a website and not a book but it’s a link always worth sharing https://noclip.website/

As far as I know, yes.. Besides simple differences like register allocation, it's difficult to prove that your code behaves the same as the target if its nonmatching. It's also just really satisfying when you get a match.

When doing standard reverse engineering, you might use something like Ghidra or Hex-Rays. This is what the developer of noclip.website [1] did to reimplement a lot of Mario Galaxy code, such as enemy AI.

I don't know where to get what they used in that video, but the closest thing I could suggest is a site called "noclip" ?

I also know https://www.halospawns.com/app used to have quake maps (dm6 at least), but can't find it now.

This isn't Ross's "Dream Software", but I find it somewhat related - at least its output. Check out noclip's website here.

There are a few other instances of things that are supposed to be spawning conditionally which aren't handled yet, like extra lapras in the beach.

I'll leave an article from Pikipedia with a demonstration gif, plus a picture of the whole title screen from The Models Resource and a small comparison I made myself, using noclip.website.

Then we take the encrypted text and use CyberChef to decrypt it.

Let's go to CyberChef and insert our pieces of evidence.

A parameter was changed from '2AMBCgIQBg' to 'CgIIAdgDAQ%3D%3D' which is just the correct base64 encoding they should have been using the entire time.

I don't think this was a hostile action by Google, I think someone just added better input validation for security reasons and it accidently broke the bad requests they were sending.

❗This is indeed the flag, but the text is encrypted with Base64. Usually, the presence of padding character "=" indicates that's Base64 type of encoding (but that's only one of the hints). To decrypt it, we can use CyberChef. Copy-paste the text and we either:

It uses a combination of magic bytes (like the `file` command), entropy analysis and character frequency detection to determine whether an output is likely to be of interest to the user.

The file type mechanism is written here[0]. There's a list of all signatures we detect here[1].

I think this can be deciphered using CyberChef...
