shiny codes for gameshark, need some help please.

In my game, I've found codes that make only shinys appear, or make only specific pokemon appear, I once also made it so only shiny raquaza appears, is it possible to make it so sa.. only shiny vulpixs appear? I know I and use my code to make all wilds shiny, but I've never seen a wild vulpix in the game, so that's not possible, if you have codes for gameshark sp to make any specific pokemon shiny, please post, it will help. if it's not possible, please tell me, cause I keep searching.

Well i dont know the shiny code but i know how to encounter whatever pokemon you want.

First you need the encounter master code, then the encounter pokemon code, and finally the code for vulpix. Should look like this

000014D1 000A -mastercode
1003dae6 0007
17543C48 E65E0B97 -encounter pokemon code
276AF592 A3A635CC -vulpix code

I dont know the shiny code but it would go between the master code and the encounter pokemon code, so on the 3rd line.
