Request a mod

Tastyiguana · Oct 8, 2024

Hi guys, how are you?
Unfortunately I don't know how to make mods, so I came here to make a request for one. In this case, it would be more of a modification of the original GTR 2 files, which would make each car mod installed “mix” with the vehicles in the game, making them all selectable in the same category. But with one more thing, as obviously LMP cars will be together with Touring cars and one is stronger than the other, there won't be fair competition, so let there be separation by performance, for example: between 100HP and 200HP, 200HP and 300HP and so on.
I know it's a pain to make a mod, it's almost like making an entire game, programming codes and scripts, so only accept this idea and request if you want to and can do it, ok?
Sorry if my English is wrong here.

It's actually not that hard, it would only be tedious and take a lot of time.

There are three files that are needed to get a mod to show in the game: a GDB file, a TXT file and an Icon.

If you look in your GameData folder you will see that each mod or category has these three files.

It is the GDB file that defines your mod. You would need to give each category that you want, a specific name: for instance MyMod_100HP = Porsche 911 , which goes in the GDB, then you put that reference: MyMod_100HP in the CLASSES line of a Porsche 911 that you want in its .CAR file. And so forth for all the cars, ans all the categories.

The txt file just describes your mod, and the icon.tga is the picture that is shown when you choose your category in the menu.

Just study the GDB file and a TXT file of a mod, and then create your own.

Just copy existing files, and edit them to what you want. Start with a couple of cars and then when you get a feel for it, add to it.

This is the GDB that I created for a 1966 CanAm mod that I put together for myself:

One thing to watch for when naming classes - any three consecutive characters in multiple class names will be lumped together by the game. For example, FER360 and FER475 would appear in the same class, but F360 and F475 would be different classes. It can take some creative naming to get everything working.

A bit of heresy to the purists, but I tired of deciding what mod to use for a race, especially since most used basically the same cars, so I merged all my GT series into one big "International GT" series. I based my GT1, GT2, and GT3 classes solely on performance (lap times at a couple of test tracks), regardless of engine type, aspiration, stock based or purpose built. (Once sorted I found it interesting that all the GT3s are between 400hp-500hp, all the GT2s between 500hp-600hp, and all the GT1s over 600hp.) Also combined a half dozen Porsche Cup mods into one (none of my tracks support it but I could field a Porsche Cup race of 80 cars). Menus are now merely GT1, GT2, GT3, Porsche Cup, Club (cars noticeably slower than GT3), SuperGT (cars noticeably faster than GT1), and spec series for any cars of which there are at least 20.

Hello sunalp2 and jgf!
Thank you very much for answering me and especially for the tips. I'm very grateful, because there were cars that I would really like to see racing together and thanks to what you said, this will be possible.
Thank you very much guys!
