This time guys I'm sure at 101% that isn't a repost 
I'm fooling around in a website that have some codes for PS1 games, when I found that particular one, I've tested immediately. This code works ONLY for the PAL release and is about to change the language (who have the PAL version will understand me) and you can select also the US language, apparently is the UK language but force the game to load the NTSC-U into the PAL!!! Then you can have Acura cars, Honda with changed nameplates and Dodge version of Vipers and Concept Car. This is an interesting fact... I dunno if is possible to load the NTSC-J into the PAL.
The code is: US: 3004DDA4 0000
UK: 0001
FR: 0002
GE: 0003
IT: 0004
ES: 0005
EDIT: I've tested this code deeper. The conclusion about Acura/Honda is this: when you buy a car with this code active, in the garage is still displayed the PAL name of the car, but when you buy it in the dealership, shows the USA name. Ah, you can't load the NTSC-J into the PAL
