Hello, I've been trying to capture Smash4 packets with with WireShark, but they fail to appear even though they are being sent. However when I use the Internet Browser the packets show clearly. Is there any way to capture the packets of smash 4?
Well I don't know if there's a good method right now for accomplish that but I think almost all important traffic coming/going from/to Nintendo or game servers is TLS os SSL encrypted so you would need to get the proper certificate or session key to decrypt that traffic,
I don't think you can MITM without more system permissions, you can always try to scan the WiiU RAM and check if the certificates or keys are stored on it.
I once tried to hook into the NSSRead and NSSLWrite function, without any success. Most the Miiverse stuff is using this functions. All other online gameplay are using the normal send/recv with encrypted data. At least you can log it
If you also want to hook into the send/recv function take a simple hbl app with a functions patcher (like hid to vpad) and change the functionshook (*wink*)
