I'm getting flickering black textures on this and a few other 2025 cars, it is something I'm doing wrong?by TomMK - Grand Prix 4
Re: Introducing: GP4 Memory Access (by Carl_gpgames, Öggo and ZaZ) - 8 months ago
Yep my FolderExtender.dll is in my gp4 root folder. I've disabled Windows Defender - I have no other anti-virus running - and added an exception for GP4 Memory Access, and started again with a fresh install of both GP4 and GP4 Memory Access, but always the same result unfortunately, it doesn't trigger the file injection. Such a shame, I thought this would be a game changer for meby TomMK - Grand Prix 4
Re: Introducing: GP4 Memory Access (by Carl_gpgames, Öggo and ZaZ) - 8 months ago
No luck. Even with verbosity high there are no further entries for FolderExtender. Here's my full gpxload.txt:by TomMK - Grand Prix 4

Re: Introducing: GP4 Memory Access (by Carl_gpgames, Öggo and ZaZ) - 8 months ago
No luck I've named the files as car_ferrari_car1_lod_0.gp4 and so on. Placed them in the Cars folder. But the new shape doesn't appear in the game. The log says the dll has been injected correctly: : DLL successfully injected: C:\Users\TomMK\Grand Prix 4\FolderExtender.dll : DLL injection completed successfully. Has anyone else go this DLL working?by TomMK - Grand Prix 4
Re: Introducing: GP4 Memory Access (by Carl_gpgames, Öggo and ZaZ) - 8 months ago
Trying to use FileExtender to add cars but it's not working for me, I just get a Jaguar instead of the car I'm trying to add. Can someone give an example of how to patch a car shape and textures please?by TomMK - Grand Prix 4

GP4 Central to close - 2 years ago
GP4 Central will close soon. Unfortunately I've not had the time to devote to the website in recent times and so have decided to shut it down. I had a lot of fun creating the site, especially the GP4 Central Championship, and want to thank everyone who supported me in whatever way over the years. Download anything you want while you can! Cheers, TomMKby TomMK - Grand Prix 4
Re: Bahrain Tyre Wear - 3 years ago
Your tyre wear values look OK but there are other values that look out-dated - try this: 12 ; desc1= Front wing 12 ; desc2= Rear wing 23 ; desc3= 1st gear 30 ; desc4= 2nd 37 ; desc5= 3rd 44 ; desc6= 4th 51 ; desc7= 5th 58 ; desc8= 6th 14 ; desc9= Front wing 14 ; desc10= Rear wing 21 ; desc11= 1st geaby TomMK - Grand Prix 4
Re: Custom Championships? - 3 years ago
If it's just the series of tracks you want to customise this is very simple. GPxPatch has a tab called GPxTrack where you can set the 17 tracks for your championship.by TomMK - Grand Prix 4

Re: Loading times: it's all random - 3 years ago
No this behaviour has been noticed before. Loading times do get slower after the first time. I don't believe a cause / fix has ever been found.by TomMK - Grand Prix 4

Re: Magic Data Discussion - 3 years ago
The problem with desc46 is it affects the player car differently to the AI so as that value varies between different Magic Data, your performance will vary against the AI for no good reason. So I keep desc46 constant in all my MD, and only vary desc47 to simulate air pressure differences (i.e. cars go faster in a straight line at high altitude, Mexico City being the best example in recent yearby TomMK - Grand Prix 4
Re: Cars going too fast ? - 3 years ago
Seems reasonable - in 2001 the pole laptime was 1:22.2 and if you're doing a quick race then the cars will have low fuel and new tyres so it's reasonable they would be approaching the pole laptime.by TomMK - Grand Prix 4

Re: MiniNord Track V Final - 3 years ago
I get the same issue - game freezes when clicking Drive. I've tried a few things but can't get it working. Pretty sure it's the .dat file that's the problem.by TomMK - Grand Prix 4

Re: Missing weight value in car physics (heavy cars braking fix) - 4 years ago
Nice find! I ended up just leaving car weight at the default in all my mods to avoid this bug, and compensated in the performance file to get accurate laptimes.by TomMK - Grand Prix 4
