Thanks to the great work done by 15432, we can finally decrypt the MIG flashcart firmware code. Here's what we've learned so far (1/9). github.com/15432/mig_researc…

7) Decrypting the "update.s2" file is a matter of stripping away a first layer of TEA encryption, parsing metadata, decrypting the actual firmware code with the right AES key and, finally, deobfuscating the resulting plaintext through their custom XOR-based algorithm. (8/9)

8) This last XOR-based algorithm is an absolute abomination of mixing random values and multiple seed sources just to make it as hard as possible to reverse engineer (even Ghidra wasn't able to produce an accurate decompilation of it, despite having support for Xtensa). (9/9)

This is a major update, so Atmosphere will be broken until updated. Thank you all for your patience!
