Cheat codes

[benvlieg]

Does every title in this collection have cheat codes?
And what are they?
I've tried searching around online but I couldn't find a definitve answer.

Do you mean programmer cheat codes like the Konami code, or cheat codes like a PC trainer?

[benvlieg]

Stuff like the Konami code.

what is the konami cheat code?

[benvlieg]

It's a cheat code that Konami put in most of their early games. Its: up up down down left right left right a b start. In the NES version of Contra, it gives you 30 lives. Or at least it should, but I can't get it to work with this collection.

Some games do and some do not.
Contra (for the NES) code is: Up Up Down Down Left Right Left Right B A B A before the word Contra scrolls to the title screen is finished.
That'll give you 30 lives.
Super C for the NES's code is: Right Left Down Up A B Start. Same as before, finish before the scroll is done for the title screen.
That'll give you 10 lives.
Contra Hard Corps Code is: At the main menu, using controller 2, press C, B, A, RIGHT, LEFT, C, B, A, RIGHT, LEFT, C, B, A, RIGHT, LEFT.
That'll give you 70 lives

Those are the only 3 I have memorized because I've input them so much when I was younger playing these games.
