Double Dragon III: The Sacred Stones Billy And Jimmy For One Player
Select two player mode B (you know the one where you can hit each other.) When you start you have to fend off some badguys. After you kill them start killing jimmy with billy near the guy who is sitting on the mat. Make sure you don't get too close to him so he doesn't start talking,though. When jimmy is dead and flashing move billy toward the guy who is sitting guy. Do it fast, before jimmy fades away. If you do it right, jimmy should stand back up with little life. When the guy dies, more badguys willcome. Make sure you can kill all of them without getting jimmy hurt. If he falls, then he dies and the trick is over. When all the badguys are gone,make jimmy leave the room first. When billy leaves he'll be the only one on the other side of the building. Check your character menu. Jimmy should be there unscathed and you will be able to change between him and billy throughout the game as one player.
