I haven't looked at Tekken Tag in ages (aside from the fact that the game is working, unlike when this topic started 13 years ago), but the demo mode has no music during the fights (as with Tekken 1-3), a cheat may be possible via this route if it's just a flag set. Note that if the music is disabled, other background effects such as the lightning on Hwoarang's stage will still be heard.
In the mean time, here's one for those who want to see the CPU in the demo mode fight to the death without the demo ending abruptly with 37 seconds left (not sure why Namco even put that in the game, but then again the Street Fighter series did the same thing). This cheat will make the demo just like the first 3 games. Yes, sometimes I like just sitting back watching the CPU kill itself over and over.
The cheat applies to the US versions [tektaguc1] TEG3/VER.C1 and [tektagub] TEG3/VER.B (both memory locations are identical; note that I haven't looked at the TEG1 or TEG2 versions yet so I don't have cheats for these right now).
