In the Badlands, near the Hecht Ranch you should see a herd of buffalo. Near the buffalo is a dilapidated house. Behind the house are two mesa like land features. In one of them there is an opening into a mine on one of the cliffs. Go into the mine. When you walk into the mine, the path will split. Go right. Pick up a dynamite barrel behind the mine carts. Take the barrel back to the house. Go to the back of the house and set the barrel down next to the chimney. Back up and shoot the barrel. Near the chimney a hole should have been blown into the ground. If you jump into the hole, you will collect every ammo type you need.

When on a horse, hold the dash button while repedately jumping. If you time it right, you should go at about double the speed of the normal horse.

During the battle with Hoodoo in his casino, you will notice that he is on the balcony upstairs. By making your way up to the second level, you will find a second set of stairs that should have red wallpaper on the walls leading up to the third floor. Climb these stairs to the very top where Hoodoo's office is. This should skip the battle and immediately let you finish him off.
