GBA SP gameshark codes not working

Ok I just recently ordered a Gameshark for GBA SP and for some reason the codes for Pokemon Ruby and others end with like 16 or 32 not an even 12 or 36 since each line only lets you have 12 blocks and not 16. If I do type in a 16 block code I have to use another line with 8 zero's after it and the code wont work.

For instance:

Pokemone Ruby Master Code:

9E6AC862 823AB7A8
46B7D9E4 A709E9E1

but you can only have 12 on each line and on the third line it will have 8 zero's and when I try to play the game it says wrong Master Code.

***? How do I enter this games codes which don't come out evenly or are these just bad codes?

I think you found codes for some other cheating device like Action Replay or something.
