I checked out the hack that is mentioned
here but I'm reasonably certain it's not meant to stop Sims from autonomously playing SSX on the console (the one that sits in front of the TV) and if it was, it doesn't work in Seasons.
The reason I ask is that while I was testing the new EP out, I noticed that every time a visitor's Fun dropped just a tiny bit he would wander over, pick up a game controller, play for about five seconds, and then stop. And then repeat. So, I'm thinking that either there should be a motive check before playing and/or that visitors should only play when invited to, or when there's a party going on.
