I chose not to list the GB movies or the other systems.

Hints that it's fake:
ESRB logo isn't in the bottom corner
Nintendo seal of quality is on the front cover not the back
Refusal to show the back of the box
No "Only for GBC" logo on a GBC game
If they claim you can play a GB / GBC game on a Nintendo DS
If the cartridge says "Game Color" insted of game boy color or only "Game"
Multi-game cartriges, for example Pokemon Crystal and Diamond in 1 cartridge
If it's in English and says "Pocket Monsters" on it
If the cartridge is a weird color. (Ex. Green insted of blue)
If the cartridge isnt colored at all
If it's for the wrong system. (Ex. Pokemon Sapphire on GBC) [There is an exeption to this.. Pokemon Yellow is for GB and GBC I believe. I dont think there's any others]
Pokemon for original Nintendo / Famicom
If the box doesn't say "Gotta Catch 'Em All" and it's in English
If they say it's brand new but the box is flattened

All info theoretically correct as of 12/13/06
