what are the teams that it unlocks?

it unlocks 'Special Guests'

and EA teams 1-4


found at the 'rest of the world '

that code unlocks Port Vale also from English 1st division, they are not under England league, they are under Rest of World

I'm playing on PSX and these teams (Guests, EA 1-4, and Port Vale) are all readily accessable without codes.
Does anyone know how to get the other lower division teams on PSX?
Help please.
