After beating the Elite 4 in LeafGreen and catch 60 Pokemon, you can go to talk to the Team Rocket members just before Mt. Ember. So inside there there are some things (I first thought it was just like the displays they have in museum), who say something. Every one contains one or more 3x3 matrices, where some cells are bolded (I will use * for them).
I will write every one from top left to bottom right:
*+ *+ ** | ** *+ ** | ++
++ *+ ++ | +* +* *+ | **
++ ++ ++ | ++ ++ ++ | +*
--------------------------------------
** *+ +* | +* *+ *+ | ++
** ** *+ | ** ++ *+ | *+
++ ++ ++ | ++ *+ *+ | ++
--------------------------------------
** ** *+ | ** ** *+ +* |
++ +* +* | *+ ** ** *+ |
*+ *+ *+ | *+ *+ *+ *+ |
--------------------------------------
+* *+ *+ | +* ** ** *+ |
** ++ *+ | ** ++ +* +* |
*+ ** ** | +* ** ** ** |
--------------------------------------
and then in the top room we have 8 messages:
1)
2)
3)
4)
5)
6)
7)
8)
After searching the Internet both with Yahoo! and Google search, I found the meaning, but not the methodology. I don't have an Alakazam in my party, that's why I am asking you experts, how to crack that code?
PS - If this is something really trivial in newer generations, excuse me, but I am a guy of the 251 Pokemon.
