Gran Turismo: changing the time of the day of the track

    After 21 years I have found an interesting thing: you can change the time of the day in any track. Of course this is possible only with a Cheat Device. Before to start, you must know some things:

    - Works ONLY Simulation Mode and ONLY on races, then NOT on Time Attack or Hi-Fi Mode, but you can make ONLY free runs, because if you start the qualify or the race, the code lose the effect, but still have the lights of the car turned on if you have chose a night track or off if you have chose a non-night time track

    - As said above, you must have a Cheat Device. The only code that you have need is the Track Modifier. The value for the PAL version is "300B620C". The other four digits must are from "0000" (Grand Valley SpeedWay I) to 003E (END, one of the hidden tracks. The other is rogo-test, 003D)

    - This work also with both hidden tracks

    - When the time change happen, the sky will glitched, showing things of the original track

    - This work with every track and then every time, because every track have different times, for example High Speed Ring is a day time track and Deep Forest a sunset track. Then you can have a night time Autumn Ring Mini (using Route courses) or a cloudy Grand Valley SpeedWay - East Section (using Trial Mountain)

    Now, finally, I will say how to make this. There are steps:

    1) Activate the Track Modifier BEFORE to enter the race. For example activate the Special Stage Route 11 code and enter to the Grand Valley Endurance Race
    2) Once loaded, you will notice that the track isn't Grand Valley SpeedWay, but Special Stage Route 11
    3) Then enter to the qualify. You will race in the original track, then don't worry. If the lights of the car are on or off means that is correct
    4) Press start and press on "skip qualify"
    5) Once loaded the pre-race screen, enter to the free run and voilà! You have a day time Special Stage Route 11!

    Now some trivia about this:
    - You can race also in licence test tracks. Are named with the own name, or rather, L_X-Y. The X stands for the type of licence (B or A. There aren't IA tests) and the Y stands for the test. From 1 to 7 for the B Licence and 1 to 8 for the A licence. The last B test is missed because it is a full track test, like the IA licence
    - You can race in alternate versions of some tracks, with open pit and where this isn't possible is only a clone with closed pit
    - You can race in 2 players tracks. Before the track name there is a "2P", then the track name
    - You can race in Hi-Fi tracks and there is a "HiFi" before the track name
    - There is also the Max Speed Test, but it is a Test Course clone with a different lap finish: the 1000m. The start is always the same. The course minimap is also less detailed
    - If you use the value 003F+ the game will crash
    - The rogo-test track is Autumn Ring Mini with a super shiny car
    - The Grand Valley SpeedWay is the only track that have different names. Is called Grand Valley SpeedWay I when the pit is open and only Grand Valley SpeedWay when the pit is closed
    - The Special Stage Route 11 is the only track that have both open and closed pit for the reverse track
    - The END track seems somewhere in Trial Mountain
    - There aren't the arcade versions of the tracks

    New images!

    END new day times. Originally is a sunset track

    Two more "new" night tracks

    Sunset Clubman Stage Route 5

    More images!!!

    Another day, other images

    Finally I've remembered to write the codes for choose the track. I will write the track so: #TRACK NAME and below the basecode "300B620C" and next to the value (from 0000 to 3E). Then an example is:
    #Grand Valley Speedway I
    300B620C 0000

    If the name of a track have the "Clone" word means that is a totally copy of the original track and the "Closed" word means that have the pit closed. Then the codes

    The ingenuity of the modding community never ceases to amaze me, even after all this years. Now try to find a way to mod rain :D :lol:

    Seems like only the sky is changing. I guess the ambient lighting is baked into the textures.

    I'm sorry, but maybe is impossible... I've used a Cheat Device for changing the time... Isn't a MOD :D :lol:
    Maybe Xenn can help us...

    Yes, you're right. Only the sky change, but the illumination is always present also you race in a day time Route course. Maybe with MODs is possible to edit this and make a completely "new" track, maybe also selecting the time before the race

    Maybe not rain. But a wet track? I don't know if you can reduce the grip of the track surface (IIRC simulation mode tracks have less grip than arcade - if this is a simple multiplier maybe we can reduce it further to simulate rain) and add more reflections to the road surface.

    Maybe you're right... But GT1 is an obscure game in fact of modding... But if it is possible will be the wet Special Stage Route 5 from GT3
