I havn't seen anyone post the actual AR code for shiney Pokemon, so I will post a more complicated code that is very riskey to use:
0648a5ec
c9d42bb8
01763a7e
e1b3e957
4c241b5a
f1c39edb
ea8f704a
45ee01d1
022ea6cd
594a7718
d2bf38b5
7e300c38
8343300b
adef57ca
27c35f73
a8e9e879
How the code works: (this code only works 25% of the time) Type in your caode and start game. Run into grass until a wild Sunflora appears. Catch it. Go to PC. Flip through boxes until you find a box with 2 or 3 eggs in it that you didn't originally have (Bad EGGs). Select the first Pokemon in that boxs summary. Continue to click down until you get to a summary of Bad EGG displayed as a backwards (?). Click A or B to exit the summary. Now in your PC, that Pokemon will be invisible. Click and drag the invisible Bad EGG to any part of the box and switch Pokemon. The Bad EGG will then change into a shiney version of the first Pokemon in that box. Glitches may occur.
