Manhattan Project codes

[Tinuvielsdreams]

First of all I apologize if there is already a thread on this somewhere...

Does anybody remember the old start menu cheat codes for Manhattan Project. I remember I used to be able to get right to the final Shredder battle.
I have Manhattan and Ultra still working but Ultra may have been too early for cheat codes because I only remember getting it to work for Manhattan project.
