60 FPS

Last update: September 6, 2021

Cheat originally made by asasega. I ported it to more game versions and expanded it with more features.

An improved 60 FPS cheat. I expanded it to re-enable tire smoke effects and the rear view mirror, originally disabled for performance reasons when running the game in Hi-Fi mode (that mode is not present in GT2, but it’s a leftover from GT1).

WARNING: When this cheat is in use, existing replays and AI ghost in Rally events will break. Consider switching back to 30 FPS for those events.

Combined Disc

Last update: March 8, 2022
Arcade and Simulation Modes on one disc.

Gran Turismo 2, other than being one of the more fondly remembered installments of the franchise, has one unique aspect not seen in any other Gran Turismo to date – it’s split between two discs. This modification combines both discs for an ultimate and complete version of Gran Turismo 2.

Due to the nature of this mod, the setup process is slightly more involved than the usual:

  1. Download the setup script. Do note that GTVolTool used by this script is Windows only.
  2. Install Python 3.8.0 or newer. If you don’t have it installed yet, Python can be downloaded from here:
  3. Run setup.py by double-clicking it like any other executable file. If due to your local setup the script does not run, launch it with python setup.py or python3 setup.py in the Command Prompt.
  4. Follow the on-screen instructions. The script will bring up a system file picker to select files by default, but this may be changed by starting the script with a -t parameter. Remember that you may easily “type” the full path to the file by dragging it to the command line window - it’s useful for easily putting full paths to the Arcade and Simulation discs.
  5. Wait for the setup to complete. Please be patient - it takes a while, as it needs to repack discs and the game assets.

Version compatibility

The modification is compatible with all game versions, except for NTSC-J v1.0.

Hardware compatibility

  • PSP/PS Vita can use the full version of the mod in PBP format.
  • On PS1, the full version is compatible with XStation. You should opt for the lightweight version (without FMVs) only if burning the image on a physical CD.

Combined Disc is also compatible with RetroAchievements! Those using it for their GT2 playthroughs may safely move to using the Combined Disc and achievements will continue to work as expected.

Metric units code

Last update: September 6, 2021

A code changing measurement units in the NTSC-U version of the game from imperial to metric.

Currently converted units:

  • Speed (mph -> km/h)
  • Weight (lb -> kg)
  • Distance (ft -> m)
  • Torque (lb/ft -> kg/m)

To do:

  • Spring rate (lb/in -> kg/mm)

PAL version of the cheat fixes a “Launch speed at X mph” text, which was wrongly labeled as showing miles per hour, but showed kilometers per hour.

Full detail AI cars

Last update: September 6, 2021

By default, Gran Turismo and Gran Turismo 2 both use very aggressive LODs for AI cars. The highest LOD level is reserved for the player, with lower LOD levels used by the AI depending on distance from the camera. When playing the game on the native resolution it’s nearly impossible to notice, but of course with upscaling LODs become much more obvious and jarring.

To counter this, I created a cheat forcing all cars on the track to use the highest LOD level, previously reserved for the player. As a result, the game looks far better than originally.

Slightly higher draw distance

Last update: September 6, 2021

Fair warning – this cheat doesn’t do wonders. The game’s draw distance is determined by the track data itself, and so it’s impossible to increase it arbitrarily. However, Gran Turismo 2 has a slightly higher draw distance in replays than it does in races. With this cheat, I enabled the replay draw distance in races.

HUD & rear view mirror toggle

Last update: September 6, 2021

By default, it is impossible to completely hide the UI in GT2 during races or replays. Additionally, the rear view mirror only shows in the bumper camera and it cannot be down in chase cameras. This cheat allows to toggle the rear view mirror by tapping L3 (cycling between “always on”, “default” and “always off”) and toggle the entire HUD by holding L3.

Replay cameras in race

Last update: September 6, 2021

By default, Gran Turismo 2 has 3 camera modes in race, but 9 modes in replays, with the cinematic camera being a separate, 10th mode. This cheat makes all replay cameras accessible in race, and allows to switch the cinematic camera by holding R1.

True Endurance

Last update: October 9, 2021

Gran Turismo 2 has a single timed Endurance race – Millenium In Rome 2 Hours Endurance. However, while limited to 2 hours, this race can also end after 99 laps, whichever comes first. With this cheat, this race becomes a true timed Endurance race: like in PS2 Gran Turismos, the lap counter now only shows finished laps and the race ends after 2 hours, regardless of how many laps were finished.

This cheats improves randomly generated events (One-Make races and Event Generator races) by fixing the course generation:

  • Autumn Ring Mini and Autumn Ring Mini Reverse, previously unused in Simulation Mode, have been added to the pool of available courses.
