Press W to Shoryuken, D to Hadouken, and S to do a Tatsumaki-Senpukyaku. The Hadouken animation is the Ultra-Combo form, so it takes longer than the others. I woudn't recomend pressing 2 buttons at once, it can get glitchy.
Props to Psych833, and all I did was make it so the other Ryus are hidden :)
