You can generally find the Portuguese and Spanish variants of “Truck Rally” quite easy, but the U.K variant definitely belongs in the top of the most rare titles for the Playstation.
“2 Games: TOCA World Touring Cars/Jonah Lomu Rugby” is probably the most rare “2 Games” compilation of them all. It was released in Australia and New Zealand exclusively.
This version of the “RFU Adaptor” was manufactured to fit the Playstation consoles that came after model “SCPH-1002”.
I have noticed that it is much harder to find a boxed copy of this adaptor today, than it was just a couple of years ago.
