Only tyres Pit stop and change time of pit stop for GP2

Post by Michael82 »

Hi all!

I found a patch on grandprixgames.org for GP3.. and I applied this in GP2 with an hex editor.
http://www.grandprixgames.org/read.php?50,950791

All cc have full fuel in starting race in GP2 with one planned pit stop (for change tyres) like before 1994 and since 2010. (Doesn't work with 2 pit stop). Also, it's possible to reduce time of pit stop. (3 sec. like today, 5 sec. in 1992 or 15 sec. in 1984)
If you want the files contact me.
Best regards

Michael

Thanks for making this patch available. I'd like to try it out ASAP. Is the maximum time for pitstops 15 seconds or can this value be hex edited for longer pit stops?

What's ASAP? yes you can changed until 255 in decimal (FF im hexadecimal) but i don't know about the time of pit stop with this value.. You can changed the number line 0xA25F0 : 58 1B (default value) must to be changed by 01 00. 1B is the default value (8 sec.) and 00 is 2-3 sec. approximately... I don't know for the other values changed. Say me if you see another things..

As Soon As Possible...
Wow, I guess people really don't use that expression much in these modern times. And I didn't even notice there was already a link to the download. I feel so old now... :lol:

Thanks for the info. I'll play around with it and let ya' know if I find anything new.

Sounds like a great feature. I've always preferred the tires only rule, like it was back in the 80's and early 90's. This might be a newbie question, but once you have the hex editor program, what file in gp2 do you edit to change the races to pit stop only?

Hey Michael!

Sorry for replying much later than I promised.

If is just changing a value, setting up a patch should be no problem. Except that some of my tools are not working anymore since I updated my system to Windows 10 lol. Once I get this solved, I will add this feature to my editor. But I also want to make a standalone patcher so you don't need the full editor for this to work.

I haven't been able test the values yet, but can you clarify something? You say you changed the value from 58 1B to 01 00 and as I understand you said that the 1B to 00 is what matters. This is not unlikely in GP2 values since the whole thing is probably a single number and the 1B is what accounts for most of it. Does changing only the 58 part produce any changes? Can you make tests with 00 01, 00 02 and 00 03 and them 00 10, 00 20 and 00 30 and post the results? That way we can make more sense of it to decide the better way to produce a patch.

Hi Roberto!

Late answer too... sorry
It seems to me that change 58 number isn't very important. I didn't see any change during the game with your proposed values. However the number 1B match to time of pitstop and i changed this with 01 values (3 seconds approximately) and max value "FF" (More one minutes).Others values are for the fuel. I hope i was clear with my bad english..

Hi Michael,

great find.
Changing "xa25fa" and "xa25fb" from "58 and 1B" to "01 and 00" is easy
with an editor like "frhed".
Works great in the game.

Now I want to change the other data from the "GP3 2010 fuel/pit stop" patch
in my Gp2.exe.
Unfortunately I can't find every offset.

Please send me your files.

Maybe we should explain how to change this!?
- open track in TrackEditor
- click Pitlane
- click Pit Stop Strategy
- doing 1 Stop : 100% (2 Stop and 3Stop to 0%)

Hi Andreas!

Sorry for the bad explanations.. On this picture, you can see the offsets and the values that you must change (in red) and i surrounded in red the value of time of pitstop. Do you want that I send a modified version of gp2?

Thanks again for making this info available. It's just what I need for more realistic pitstops when using WSC carsets. I've also found out that the pitstops can be set to last much longer than one minute. Just change the values for 0xA25FB in conjunction with 0xA25FC. Right now I'm using 1F 01 for 1m14s pitstops more or less and I've kept them on a normal pitstop strategy as opposed to a one stop. I had it previously set for 2m12s but it caused problems with the cc cars. It seems that the cc cars on the same team have the same fuel laps loaded so they sometimes tend to send a car in for fuel while the pits are occupied. When one car parks behind the other car still being serviced this can sometimes block the cars of other teams trying to get into or out of the pits. If the fuel laps between cars on the same team could vary by 4 to 6 laps that could be enough to keep one car out on the track long enough for the other car to finish the pitstop. Is there any way to separately edit that data for each car on the same team?

After some headache, I was able to completely remove refuel from the game, so now it works with any number of pits in the race.

I also created a patcher so you don't need to use the hex editor. The problem is, I didn't notice one of the numbers Michael was changing, so it is just changing 2 of the 3 values (the missing one is the one he was changing to 00 28).

You can download the patcher here
