Grand Prix 2: Wet races

Hi,

I'm trying to mod the game in order to have wet weather races. I've downloaded GP2Wet, but encountered some issues I haven't been able to go round:
- The tool apparently could replace some Jam files, because I get darker visuals, but I'm not sure all are replaced, some tracks seem to keep quite a bright tarmac.
- The tool fails to load some executables apparently thought for sound, which are 16 bits and cannot run on modern hardware. I'm wondering what they do and if I could replace sounds manually ? If so, could anybody help me on this ?
- There's an issue with tyre grip, the CC cars cannot find any ! Launching a quick race on Imola , the CC cars don't reach 150kph in the first straight. (I haven't check the player's car grip yet). There's a window to choose the tyre grip in the tool, but I can't find any action to update the game.
So I'm thinking of editing the tyre grip through another tool, but I'm a bit lost when I check GP2Edit. Is there a global tyre grip factor, or should I edit all the different values tweaking the grip, for both player and CC cars ?

Thank in advance, I appreciate any help / hints I can get.

(or better, if someone has already created a GP2 install with wet weather, i'll gladly test it !)

Thank you, sorry for not answering sooner, I've kept off the forum for quite a while.

I've downloaded the archive, i've launched two races to check the AI behavior, it seems to be working quite well. Do you know if there's a single texture to edit to change the tarmac ? I'd like to have less bright patches around.

You mean the tarmac like this

Hi,

nope, I was willing to reduce de contrast on the intermediate texture.

I did some checks with your install, it kinda work, but I was looking for a full wet version. So I tried to run GPWet again in your install, but it didn't work: the intermediate setup was kept, with laptimes 2 to 3 seconds slower than dry tarmac.
So I started from scratch again, doing things manually in dosbox (not using the windows version).

It did work (visually it's ok, apart from monza's tamarc being to bright), but I'm struggling to understand how I'm supposed to tweak the grip ? First time I used the default 196 value, and AI lap times we almost as if the track was dry. I change the value to 256, and got more logical lap times, the AI is now around 5 second slower than on dry.
Is it how it's supposed to work ? Default value is dry, and I choose the value I want ?
