Rosetta AOT Caching on Linux

The docs on https://developer.apple.com/documentation/virtualization/running_intel_binaries_in_linux_vms_with_rosetta#4239539 are sparse and incomplete and don't tell you at all how to set this up. Lets trial and error our way through this.

If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

Find out what codec you're using

1. Play a song on your headphones
2. Option (⌥) click the Bluetooth button at the top of your screen
3. If you're using AAC or aptX, you can stop here—those are the highest quality codecs.

Change your codec to AAC or aptX

This guide assumes you have previous experience with hactool and messing with your NAND. You aren't supposed to blindly copy commands in this, so read before pasting!

Also, the Python sections require Python 2.7 and pycrypto. Make sure your hactool is v1.2 or above.

Nintendo Switch RSA-PKCS#1 Public Key Recovery

This is a short writeup of a fun (but ultimately pretty useless) attack I implemented on the Nintendo Switch a few months ago resulting in the recovery of some otherwise unobtainable RSA public keys. Since public keys aren't private keys, this is pretty useless, apart from letting us validate some signatures on PC. Even so, the attack is a pretty cool one, so I thought I'd write it up.

Every Switch gamecart has a unique certificate (called its "CERT"), storing an RSA signature followed by some kind of unknown but unique encrypted data. I was trying to reverse how these certificates work, and the obvious first step was to try to see how they were validated. However, when I tried looking through the FileSystem (FS) module, which should be responsible for validating these certificates, I found no references to the format at all. The "CERT" magic number was nowhere to be seen, and I couldn't find an RSA modulus that validated the signatures I had. This was in
