Gran Turismo 4 Cheat Codes Discovered Nearly 20 Years After Release

Cheat codes have been found for Gran Turismo 4, which launched almost two decades ago in 2005 for PlayStation 2.

These cheat codes were discovered by Twitter user Nenkaai, but it’s unclear how they found them in the first place. These newly uncovered chat codes provide benefits for players when the corresponding buttons have been input into the game. However, they can only be used once 365 in-game days have passed in Gran Turismo 4:

• Earn 10,000,000 Credits in the GT Mode screen: Select, Left, Right, Right, Down, Up, Up, Left, Down, Up, Right, Left, Down, L1, R1, Select
• Pass any license in the License selection screen: Select, R1, Select, R1, Select, L2, L2, R2, R2, L1, Select, L1, Select
• Earn a Gold rating at any specific license test in the License Test selection screen: Select, Select, R1, R2, L2, L2, Select, L1, R1, Select, R2, L1, Select
• Earn a Gold rating at any event in the Event Course Selection screen: Select, L1, Up, Up, Select, R1, Down, Down, Select, L2, Select, R2, Select

Furthermore, the prizes that come with earning a gold rating in events are also unlocked as well and 24-hour races can be skipped over. The codes apparently even work in the 2006 motorcycle game Tourist Trophy, which uses the same game engine that Gran Turismo 4 does.

This is quite the find for such an old game to have new discoveries, as the franchise is one of the most influential ever in the racing genre. The latest entry, Gran Turismo 7, was released last year for PS4 and PS5, as well as PS VR2 through a free in-game update.

In IGN Gran Turismo 4 review, we said, “GT4 is the greatest ideation of GT3 that’s possible on the PS2. There’s no doubt that this game absolutely kills everything else around in terms of graphics, sound effects, and force feedback. The license tests, circuits, missions, hundreds of cars, and dozens of tracks all add up to what is still one hell of an addictive racing game.”
