Gran Turismo v1.1 Changes & Cheat Code Compatibility Explained
Gran Turismo v1.1 Overview
Gran Turismo v1.1 was not a major content update but rather a maintenance release focused on stability and bug fixes. If you’re upgrading from the original v1.0 release, don’t expect significant new cars or gameplay additions. The update was primarily concerned with smoothing out issues that players encountered in the initial release.
Key Changes Between v1.0 and v1.1
The most visible change for most players was the renaming of a few prize cars. The CR-X EF-8 Si-R and Civic Type-R (which had different names in v1.0) were standardized to match their real-world naming conventions more accurately.
Beyond car names, Polyphony Digital made subtle adjustments throughout the game:
- Car performance statistics were fine-tuned for better balance
- Suspension settings were adjusted on several vehicles
- Seven tracks received modifications, likely to fix collision issues or improve lap consistency
- Menu screens had two pages reworked, possibly for clarity or bug fixes
- The del Sol LM Edition logo had its CR-X branding removed
The car garage file structure also changed slightly between versions, with garage slot data shifted by 240 decimal positions in the save file.
Do Cheat Codes Still Work?
Yes, cheat codes do function with Gran Turismo v1.1, but how you access them depends on your setup. For original PlayStation hardware, you’ll need a physical cheat device like CodeBreaker or GameShark. These devices read memory addresses in real-time and modify them according to cheat codes.
If you’re emulating the game, cheat codes are often easier to apply. Most PS1 emulators support cheat code databases, and v1.1 specifically has documented CodeBreaker codes available through various gaming databases. The important detail is that cheat codes are version-specific. A code written for v1.0 may use different memory addresses than v1.1, so always verify that your codes are labeled for the exact version you’re playing.
For those seeking specific codes, gaming archives and retro databases maintain separate listings for v1.0 and v1.1, reflecting these address changes.
Should You Upgrade?
If you own v1.0, the v1.1 update is worth installing primarily for stability. The tweaks to car balance and suspension can make races slightly different, though this is rarely noticeable to casual players. The main benefit is bug fixes and better reliability on the hardware. If you’re starting fresh, v1.1 is the version to play.
