yeah that's right, ive read the wiki site, lol

anyways ive known the code in contra even the internet technology was poor at that time, (early 90's guess), cause my cousin tell me that you can gain 30 lives with that code

and suprisingly, gradius first made that code (cause gradius 1 is the first hard to beat shumps, so the programmer put the code there and forgot to disable that code, lol)

anyways i have not tried it in salamander and life force (but i assume that also works there cause that's a replica of gradius, lol)

anyways digg also have konami code, lol
