If you can trade Pokemon from crystal version to gold version my guess is yes
EDIT: I'm not sure either. i tried to trade from crystal to leaf green, and it didn't recognize that i was trying to trade. im not completely sure i think you have to have two-hundred Pokemon on fire red then you can trade from Pokemon crystal.im not sure you can do that with crystal
There is no NPC who you can trade a Haunter to for a Gengar in Pokemon Crystal. To get Gengar you will need to trade with another player or a copy of Pokemon Gold, Silver or Crystal.
Trade it from yellow/red/green.
Can u trade pokemon between gold version and leaf green
