Bomb Defusing sort of game
 

I tried searching for it on my shareware discs but I can't even find it...
This game (that I don't remember the name) is a sort of a bomb defusing game, where you must hit a pattern to pass to the other level, in this game I don't remember if the object was a bomb or a chest or mechanism of sorts, but you need to beat a sequence of 4 colors to pass to another level.
Another interesting point is that a part of the gameplay is in 3D (there's a character that keeps talking while you make your guesses, that's the most remarkable part that I remember), and for some time I thought the name of the game was "Enigma"(because of the puzzles) just to find out it was a breakout clone that was on another disc I played on the same time as this one.
Probably we're looking for something between 1996-2001...
Oh, and by what I remember it's for Windows.
Sorry if my description is vague but I don't remember what could come in the registered version.

I have no idea what game you mean... but I also noticed that your description is somewhat too vague.

What exact code do you mean? Is it memory game with sequence of colors, puzzle with deciphering items by "right/wrong" guesses or maybe you need to assemble code part by part?

(I remembered Geekwad by the way, but while it have color-coded bomb, it's quite different from your description).

The description reminds of the many mastermind clones that I have seen. By the way, were the comments voiced or text on the screen? I think I remember that one of those clones had a virtual opponent with text balloons.

Yup, Geekwad is very far from what I'm looking for.
Looked around and it's a Mastermind clone in some part. About the game, you have a number of guesses and 4 spaces in each guess (Along with some colors for the guesses); The 3D character (it's voiced) says things like "There's a color in the wrong place". Strange is that is not on the list of Mastermind clones lit on Mobygames... Maybe this part is only a portion of a full game (considering I played a shareware/demo version)
