User:Maxoufox/TMESWC

Just writing my thoughts about TMESWC. Don't expect anything useful from this (else it would not be under my user). This is purposely written in non-wiki style, as I'm just writing as I'm going. Formatting will be done later. Everything here is done via educated guesses (disassembling the game is a pain due to StarForce).

Running the game

To run ESWC, I had to set up a Windows XP virtual machine. Then just install the game as normal.

Auth stuff

ESWC's auth isn't like TMF one. Requests and responses don't use XML, but instead uses HTTP GET parameters and CSV-like responses. User-Agent is still set to GameBox.

The game connects to two servers : https://game.trackmanianations.com/ and http://ladder.trackmanianations.com/. The SSL certificates for these domains aren't valid anymore. To make the game connect to them (the servers are still alive), you have to use an HTTP(S) proxy like Fiddler (and allow it to accept bad certificates).

Requests stuff (game)
