Pokemon Crystal Pokemon on Pokemon Diamond????

you cant trade between the old Pokemon games like crystal with diamond but you can catch Pokemon on ruby sapphire emerald fire red and leaf green that you can on silver gold and crystal even the legendary dogs you can get even get lugia and ho-oh with a Nintendo event but only on the gba games you can trade gba w/ games with diamond and pearl

Pokemon Crystal was locked out ever since the Game Boy Advance came out, this means there is no way of communicating between the Nintendo DS and the Game Boy Color cartriges. Not only are they different formats but the slot for the GBA games on the Nintendo DS does not support Game Boy Color cartriges, in other words, they do not fit. This is quite a bummer because I had level 80+ in Pokemon Gold.

You can't. The first and second generation Pokemon games like Crystal are incompatible with the later main Pokemon games

You cant you can only migrate Pokemon versions FR LG R S E

sorrry to burst your bubble but crystal is to old of a version. the oldest game you can transfer is ruby/saphire

you can't trade gameboy color pokemon to pokemon pearl or diamond.

Unfortunately,trading between pokemon for gameboy color and pokemon for ds is impossible.(u also cant trade from gameboy color to gameboy advance)sorry!!!!

You can't becuz thats a Game boy color game and you can only migrate using Game boy advance games.Sorry but you can't do this.

u can not do that you can only transfer from ruby/saphire/emerald/firered/leafgreen

you cant. :-(
