"mmm... are you sure about Magny Cours 2002?"
Quite.
I spent several hours trying,but with no success.
When GP3 tries to load the track, it instead just gives the message "wrong file type" (the same as it does with your GP3 version of the 2003 Magny-Cours), but does not CTD. It just won't load the track. This is with my GP3 Magny-Cours magic data inserted in the track, which works fine for the 1999-2001 tracks.
Now that Magny-Cours 2003 circuits by both abcdefg and Belini have been made, I have finally gotten around to trying out all of the three new 2003 F1 circuits, Hungaroring, Magny-Cours, and Monte Carlo.
Belini's 1999-2001 Magny-Cours tracks all work (and look) great, without the high processor occupancy that I experienced with his Interlagos tracks.
Alas, after many hours of trying, I have been unable to get either of Belini's 2002 or 2003 Magny-Cours to work in GP3, nor have I been able to get the 2003 Hungaroring to work in GP3, either. Does anyone have the 2003 Hungaroring working in GP3? The 2003 Monte Carlo track is the only one of the new 2003 F1 circuits that I have working okay in my GP3.
P.S. I don't know if this is also true of Belini's 2002 and 2003 Magny-Cours circuits, as I have been unable to get them to work in GP3, but has anyone else noticed that, at least in his 1999-2001 Magny-Cours tracks, the timing sectors are obviously competely misplaced? I wouldn't mention this usually as it's usually such an easy thing to correct, but in the case of these tracks with their extraordinarily large number of track sections, the track editor apparently can't cope with the tracks (at least not on my feeble Athlon 900), taking a very long time to load the track in the first place, again taking a very long time to execute any commands at all (such as zooming in on the track view), and then eventually crashing before I can get as far as finding the proper track sections.
