River City Ransom
Merlin's Mystery Shop
Stand under the fourth light from the left side in the Armstrong Thru-Way Tunnel. Press Up to find Merlin's Mystery Shop, which sells several powerful, but expensive items.
Keep money after losing
Start a two player game. When either player is very low on energy, move both players to the edge of the screen. Intentionally kill the player that is almost dead, then immediately jump into the next screen. The dead player will be present with all money intact, but one less life.
