yes i noticed that some joker commands can execute many different codes, but on different regions of the same game they might not work.
Here is som great info i found also.
This page is mainly about codes & how they work. http://www.kabmotorsports.50megs.com/about.html
BTW, i'm in the prosess of tweaking all GT1 versions (patch 1 lol) to have a better game experience, and release new features to use in Duckstation.
And have more endurance races choises on more tracks, because no rubberband and more tactics with pitststops tyre wears is more fun.
I have found new camera features to use while driving, special with autopilot activated. I have mapped D-pad left to turn on AI autopilot And D-pad right to turn him of, That way up and down D-pad is free to use changing camera to the other cars racing. I have also mapped normal racing view to D-pad left. which i need going back from the new R1 TV race camera aka aurosport. who is activated holding R1 for one second and a added to the normal change view button. I can move camera to all cars and go inside them by pressing normal camera with D-pad left. And i have a dedicated button to turn of or on the HUD on all cameras. (to go back from inside AI car i press/hold R1 to change to TV camera, then you can move it back to your car.
Anytime during race you can svitch between you or the AI driving. And now i don't have to thinking on turning AI off in cheat, because it don't autoload starting an event and then freeze the game. since the Joker D-pad code left is blocking it from autoloading.
Turn on the cheat and try the new 60 lap endurance i mapped by selecting grand valley 300, then you end up on the reverse night R11 track. Endurance - Course Modifier - Grand Valley 300 > All-night ll 60 laps. (if you think 60 laps is too long, then you can pause the game and change realtime midrase the numbers with the Total Laps In Race Modifier u 1.1 cheat (defult is 9 if activated).
By not having mapped features to R3 then ngcon contoller is usable also with less buttons on it.
BTW: I think we start adressing the BIG Elephant/deadzone in the room/Emulator LOL.
For many years ago i played gt1 and 2 a lot with EPSXE and the controller deadzone was similar to orginal ps1
Duckstation has worse at 0% in dualshock setting. I turned on show controller input onscreen in gpu setting and i switched to exsternal TV camera view in GT1 and 2. Then it shows 33% movement on controller before the wheels start turning. And if i select ngcon as my controller and map it to my ps4 or xbox contoller, then i can get the deadzone down to 7% when fully tweaked deadzone in GT1 (so then the steering is great. (but now i have no rumble action)
I don't think my goverment would allow me to drive a slow lorry/truck with this loose deaadson joints slark. and special not a racecar at those speeds,
It's cinda similar to playing a first person shooter with very high lag on the internet connection., and it kill some of the fun.
The game has some deadzone inbult plus filter to calm down twitchiness in the stick.
Anyway , back to the subject. I love my new feature and mappings in gt1 and i think you will too. Try it out, Take backup of you cheat file and duckstation ini, and just try out the beta 1,1 build new autopilot + camera + events tweaks to the game. by using my files, It cant hurt trying the free DLC lol. It's nice to drive without HUD, just you and the road, with clear view.
my plan is to setup the pal and ntsc-u 1.0 versins also and maybe the japanese too. It take days to make the game better. and dig up codes. and i take it easy when i have the time.
The Attach zip file contain 3 files
for the Gran Turismo (USA) (v1.1).bin SCUS-94194
1 is the cheat file , 2 is the memcard with a lot of money and some cars and 3 is the duckstation settings.ini.
On one of the picthures you see the toyota 2000 GT and down left on the photo you see the contoller input showing 33% movement to the right. with zero movement on the wheel.
(maybe i should re-print this post in the GT1 forum hehe)
btw, Before i began modding the GT1 i uploaded a demo race on youtube.
