Hey guys

Wondered if you could help me with a query I'm having! Me and some friends are going on a 36 hour coach drive so we're gonna break out some old school pokemon red/blue etc etc. Wondered if it's possible to link an advance playing the game to an original/colour gameboy? If so anyone know where to get a cable in the UK? We're gonna try and get 150 by the time we arrive! And wanna trade etc.

Any help would be appreciated!
