Hex code for 2-on-2

[noobi]

I did a lot of searching on this forum, but I couldn't find the hex code to change make the game 2-on-2. My reason for wanting to do this is the hopes that I can convert the hex code to game genie code for the Genesis. This is something I've already done with the ice color (this works out nicely) and I would like to try and code a 2-on-2. I was wondering if anyone knows the code to do this.

And to go off-topic for a moment, the hyper speed code for game genie works really well, although it speeds up the music too.
