Super Contra (NES)

Does anyone remember the cheat code for Super C that gave you 100 men? I know I used to use it when I was a kid but I cant remember the exact combination of buttons. I've searched the web and there are codes for 10  men and for 30 men, but I swear that there was a code for 100. I think it was something like: up up down down left right left right a b a b start. I've tried a few different combinations but cant get it to work. Please help me

hmm i'm not sure which one of these it is. I think it is one of these though:

1.At Start Menu hit Right, Left, Down, Up,A,B,Start
2.At the title screen press RIGHT, LEFT, DOWN, UP, A, B.
3.a,b,a,b,a,b,b,a,b,LEFT,RIGHT,Start

I used to know like every cheat there was for this game lol
So ya it should be one of those.
