Emulating ARM with QEMU on Debian/Ubuntu

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead

Unofficial, manual content installation for OpenRA

Manual (unrecommended) installation of the required content files for OpenRA

⚠️ This method is not recommended and should only be applied if automatic installation fails. Success of manually installing the files can not be guaranteed. ⚠️

⚠️ The automatic installation may fail for non-english content. OpenRA does not support other languages at the current stage of development and no such content should be installed. ⚠️

⚠️ Manually installing files can corrupt your game and lead to crashes. ⚠️

If you have trouble with automatic installation, please contact the developers (via IRC, our forum, the webpage comments or our issue tracker) before attempting a manual install.

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
