I only got my hands on two discs, one Codes Rousseau (number 7) and one Ecol-Auto (number 3). The seller was auctioning off about a dozen and I only 1 euro on each and left it. I though noone else would find them so I was outbid on all except 2. Here are some screenshots





Notice the picture of a custom-made CD-i controller with a digital display and buttons - Confirm, Cancel, A, B, C and D. This would of been used by the student to select the answer to the questions. The test requires the student to answer around 40 questions about driving rules in real situations illustrated with in-car photographs. Some of the photos have animation for example an indicator blinking therefore they can keep the questions short as they don't have to explain where the car is indicating.
At the end it tallies up the participants score and tells them what questions they got right and wrong in each category. Since there are 7 different tests on differents discs and it takes a while to finish one, I assume the student would sit through one theory test before having a driving lesson.
