Wonderboy in Monsterland cheats and cheat codes for PC

Useful hints:
This game has hidden coins that appear when you jump in certain spots. 

The demo screen shows a couple of these. Some of them will give you 60 
gold or more every time. 

On the screen after you kill the vampire and get the broad sword, there are 
some platforms that contain a shoe shop and a cure shop. There are stairs 
leading down to the cure shop, and there's a little mushroom-type guy. 
Wait for him to go down the stairs, and then stand so that you're almost 
off the topmost stair. He'll come back up and hit you, making you fall off 
the stairs. Hold the joystick to the left so that when you land you walk 
into the bottom step. This will drop a 60+ coin. 

On the stage just after you kill the red knight, you'll see some little 
jellyfish-type things on platforms over the water. At the first jellyfish 
you come to, wait for him to drop into the water, and then stand at the 
very edge of the platform (halfway off) and let him hit you. You'll take 
a small amount of damage, but you'll get a large amount of cash. 

Jump for coins all over the place - you never know what you'll find!
