Hello guys,
I wanted to ask information on how people used to manage league racing on GP1 and GP2. We had some leagues that did championships by comparing qualifying laps, here in Brazil there was a league that started running one of these championships, it went from 1950 to I guess mid 90's with a championship that worked on the qualy mode setup. Is there a way to run a championship on GP1 by the simulation of 10 laps ? Like a person would manage to start, do the 10 laps, save it and send to the manager of the league that would do the compare with the other players.. Is there also I way to have the confirmation that the person doing the laps is running the same carset as others? Thanks!

Hello,

The F1GP hotlap competitions used the tool called GPLAP.

The logging program is called GPLAPTIM, and there are programs to view the logs produced by it - GPLAP (console) and GPLAPW (GUI).

GPLAP disables the BHP randomization for the human player, and fixes the Grip level for the human driver to 1.
It logs all the information about the game settings (car setup, human BHP, grip level, driving aids, etc.). It also detects when a car goes off track.
If a lap is valid (not going off track), it produces an authentication log each time a personal best lap time is set.

There is a separate tool that was originally available only to the competition administrators, that could verify if the authentication logs were valid.

You can find the results of old hotlap competitions here (use the website menu to navigate to each circuit): 
SimRacingWorld - Games : Microprose F1GP : Spa Records


There is an additional tool called GPPERF that can log the car position on the track, the throttle, brake and steering controls. It produces a full telemetry tracking of a lap.
You can view the GPPERF logs using the GP Race Analyser.

There is also a number of other tools to analyze the lap performance based on GPLAP and GPPERF logs, that you can find here:
F1GP-WC Related Utilities

Please note that to run the Windows (GUI) tools, you usually need an older OS, typically anything from Windows 3.1 to Windows XP.


If you want to do a competition nowadays, I'd recommend using both GPLAP and GPPERF, as well as doing a video recording of the laps. 
For the video recording, depending on the number of laps and compression used, email might not be enough, and a file sharing service might be necessary to use.
Both tools can log all the laps you want, so even a full race if needed.


There was another type of competition, that was done in multiplayer mode. In that mode, multiple drivers are selected (one for each player).
Each player would drive his turn. After that he would save the game, email the gamesave file, and the additional log files to the next player, etc.
Full races can be done in this way. The active player drives his own car, while the other players' cars are driven by the AI.
To get the optimal performance in such competitions, you also want to use GPLAP (latest version), and potentially also GPPERF and CCPIT.

Thirdly, with modern internet connection speeds, real-time online network games between two players are also possible.


For GP2, I believe GP2LAP was used, that produces similar logging and telemetry data for GP2.


Hope this helps



Cheers
