need some help with nightmare
 

I am having trouble with the nightmare portion of the TMNT 3 game. It is rather difficult. If anyone has any suggestions, please provide them and they are much appreciated.

You could always use the cheat codes. When fighting The Shredder in Don's Nightmare, the quickest way to destroy him is to go fire off the cannon thingamajig a few times.

let's see I am done with Raph's, halfway done through Mikey's, have not started on Leo's or the final nightmare. As for Don's, I am on the 3rd level.
