It's been 20 years since I created this code ... and after all this time I decided to tell you how. Unfortunately the video is in Portuguese but you will be able to understand how to do the trick. Works with: Granturismo 1 Psx the PS2 slim Used: GT1-JAP and GT1-US With this trick you can control the trophy as if it were a car or even the licenses as if they were cars on the track. Observe the exact moments to make the exchange, and then must return to normal to not play the game. Hope you like it. There are many possibilities of combinations. It all depends on: color of the car (or tunning) track (day or night?) and also of the media used. Watch the video closely.
