Bob Simpson's GPL Trouble Shooting and Problems FAQ

Note: Anyone has full permission to reproduce this FAQ in any form or language in whole or part.


Check out WiHerr's OpenGL patch which might fix some graphics problems.
The 2004 demo doesn't have this WiHerr update, so if you run in OpenGL, it's recommended to get this patch.

You'll need to patch GPL to run on Windows XP. You can either use the "All-In-One V2" patch or to do it with the individual patches, found at
Blackhole Motorsports downloads
The order should be:
GPL v.1.2 patch
Direct3D patch
OpenGL patch by WiHerr. See above
GPL CPU speed fix
Bandwidth patch at Bart Westra's GPL Garage (not the one at BHMS) if you're going to race online

**NOTE** For questions not covered here, start another thread at SRMZ or RSC. I'll add to this as I hear of any more FAQ.
Thanks to Bazzer for helping out on this.

Newcomers to GPL...


For advice on how to install or start updating GPL, see the following sites:
Stefan Roess' site Guides for setting up GPL.
Fred Faster's site for advice on graphic upgrades to the original tracks and cars.
Average Driver's Club's Steps to install GPL 67, the 65 mod, Gem+ and Igor

General Advice


If you have GPL running well, make a backup copy. If you suddenly have problems, replace your GPL with the backup copy.
If that doesn't solve it, there is something else (hardware, virus, drivers, other program running. etc.) causing the problem.
The GPL 2004 demo is missing the gpl\exports folder. If you want to export times or if you want to use the GEM utility with the demo,
you need to create this folder in Windows Explorer (file > new > folder).

Graphics and Framerate

Can't get GPL to run in the native resolution of your display device? See Guru's Resolution Hacker

FSAA doesn't work with ATI cards
It has been reported that to make FSAA work:
1- In core.ini under [ Direct3D7 ]: DirectMirrorRendering = 0
2- In the ATI 3D tab, set FSAA to 4X, AF to 8X, Anisotropic to "performance" and Disable Truform.
(someone reports "when using Anisotropic set to quality FSAA doesn't seem to work")

With ATI cards, GPL runs as only a small square in the top corner of the screen
1- Set the line in the core.ini: [D3D7] DirectMirrorRendering = x equal to 0

When using OpenGL, there are lines in the sky 1- This problem is usually only with OpenGL and it's fixed by adjusting the graphics card
settings in Control Panel > Display > Settings > Advanced > Disable conformant texture clamp.

There's a maximum of 36 frames per second. Is that correct? 1- The maximum is 36 FPS and has to do with being made in 1998 and
a tie-in to the physics being updated at that frequency. When you run at less than 36 FPS, the cars are harder to handle so lowering the graphics
to get that max frame rate is important.
Usually at the start of a race, even the highest end system will be as low as 20 - 25 fps but it'll only last for 5 seconds until the cars spread out.

There are black bars at the top and bottom of the screen when I'm driving.
1- This is the normal view in GPL, called "letterbox". Those areas are used for other information. If those bars were filled with image, it would just show
more of the sky and legs of the driver anyway.

Mirrors pointed up, upside down or to one side of the track
1- This happens in OpenGL (not in D3D) with the latest nVidia drivers (after about 52.16) which work fine but the buffer flipping mode needs to be
set to block transfer. This is no longer the default in the 52.16 drivers.
Control Panel > Display > Settings > Advanced > your card tab > OpenGL > Buffer Flipping Mode > use block transfer.

Can't load track message
1- If it's one track, there is a file corrupted in the track folder.
Either go to the backed up pre-updated folder (you do a backup before EVERY upgrade right?) or re-download and install the track.
2- Most of the time, it's all tracks and you have the same corruption problem with a file in one of the 7 car folders. Go back to the original
cars (just the .dat file in the folder) and add back the upgraded cars one at a time making sure that GPL runs after each change.

GPL freezes while in an in-game menu.
1- This is sometimes due to a read-only file. There's a utility called CROA which will remove all read-only attributes in a folder.
2- Otherwise, it may be due to a CPU issue. You may solve it by disabling Hyper-Threading in your BIOS. However, bear in mind
that this will cause performance degradation on some applications, mainly if you are running Windows XP. - Thanks to runrun

Can't get past the first screen in GPL.
1- Usually you have applied the carsound patch but don't have 7 different car sounds in the sounds folder, in addition to the sound.dat file.

The fonts in menus go all fuzzy.
1- This is a common problem that everyone using D3D and 16 bit car skins has - but not in OpenGL. Switch to full screen instant replay mode,
switch to the Pitlane or TV2 camera, then go back to the menus. Everything should be readable again.

The track menu and replay buttons seem to degrade or melt.
1- This is a problem when using a high FSAA setting with nVidia graphics cards. The in-car, on the track image is not affected. Try lower FSAA or don't worry about it.

The anti-aliasing button in the GPL graphics menu is greyed out.
1- That button is only for the original, now obsolete, graphics card that GPL was coded for. You will need to right click on the desktop > properties > settings > advanced to enable FSAA.

Changes to the core.ini have no effect.
1- your core.ini.sample file must be renamed to core.ini. Your Explorer > view settings might not allow you to see the full file extensions. UN-CHECK hide file extensions.

Cars on the grid of a race disappear then come into view shortly after the race starts.
1- Reduce the Detail Bias in the GPL graphics menu. This usually happens at 100%. 99% is better and 74% is the next level where there is more of an improvement.
See graph below You can also change the core.ini line DisableZBuffer = x to 1, but the readme
says that you will get lower framerates. This usually only happens when a lot of cars are in view so if you can live with a few seconds of
disappearing graphics the rest of a race should be OK.

Can't view a replay or a red arrow appears.
Cannot initialize the replay system, canceling weekend message
1- In the core.ini add the following lines anywhere to increase the default of 2000 (2 MB)
[ Replay ]
ReplayMemoryOverride = 128000
Where 128000 gives about 128 MB to reserve in RAM for replay memory. The following list is a guideline made up by Pmik. Time will vary
depending on the number of drivers on-track and graphics [ Replay ]
ReplayMemoryOverride = 16384 ; (16MB - approx. 19 min.)
ReplayMemoryOverride = 65536 ; (64MB - approx. 77 min.)
ReplayMemoryOverride = 131072 ; (128MB - approx. 153 min.)
ReplayMemoryOverride = 196908 ; (192MB - approx. 228 min.)
ReplayMemoryOverride = 262144 ; (256MB - approx. 305 min.)

Running GPL in a window, the colours are weird and the buttons are hard to find.
1- To run in a window, you must have the desktop set to 16 bit colour. It seems that in Windows XP, there will be no sound when GPL is open in a window.

What graphics settings do I use for the core.ini? 1-See Here

In the GPL "View Replays" menu, some track names are missing.
GPL can have a maximum of 64 tracks (with the excrption of the 66 mod)listed in the 67season.ini file, but the number in the folder
is unlimited. But having more than 128 track folders causes some track names to not be listed. The replays are listed but the track name is blank.
If a track isn't in the tracks folder, replays for that track won't appear in that menu.
Frame rate or stuttering problems.
1- This can be due to many things, but the sound card has often been blamed. Make sure you have the latest sound device drivers. If you have a SoundBlaster Live sound card and Windows XP, you should think about changing the sound card.
2- Kill all programs running in the background PARTICULARLY MS MESSENGER
3- Reduce the Detail Slider in the GPL graphics menu. See graph
4- If you're using upgraded graphics for the cars, change to 2D wheels.

GPL runs incredibly fast, or at variable speeds.
This is becoming a very frequent problem as more computers, expecially laptops, use imbedded power saving features.
1- do0g has created a "Power Monger" utility that will solve this easily. Find it at this location
2- You need the fast CPU fix from Papyrus (this is for CPUs over about 1.3 GHz, but can be used as a no-CD patch on any speed machine).
3- Laptops have a feature that changes the clock rate of the CPU to match what it thinks you are doing. Intel's "SpeedStep" or AMD's "Cool n Quiet"
needs to be set to maximum performance. The newest GEM+ has a button in the "Configure" window (Disable Intel SpeedStep) which will keep that
feature from coming on.
4- Some desktop CPUs now have power saving features that need to be switched off, like Intel's "SpeedStep" or AMD's "Cool N Quiet". Find
power options under control panel > power options. See the picture below for settings.
Or use the SpeedswitchXP utility.
5- It's been reported that sometimes patching GPL with the "Fast CPU fix" can cause the slowdown or speedup. However if you don't use that patch,
you won't be able to run the 65 mod and possibly future mods.
6- Go to Control Panel > Power Options and change the Power Scheme to Home/Office
7- An easy solution is to use GEM+ which is a utility to set up parameters of GPL before actually running it and there's an option for
disabling SpeedStep. See here.

Crash to desktop (CTD):


General problems. This can happen immediately, after most cars are drawn or after minutes of driving.
1- Disable the screen saver or power saving settings.
2- Overheating will happen if you are running maximum graphical upgrades with a lower powered computer or not getting enough air flow. Dust off
components and/or reduce the graphic settings in the GPL graphics menu or the screen resolution or the FSAA to none.
3- If you are using Windows XP or an NTFS file system, make sure that under the Sierra folder > properties > general > advanced, allow indexing
service is enabled and "Compress" is disabled. 4- Click on Start > Run > dxdiag to check for video and sound problems.
5- Run GPL without car graphic upgrades, then upgrade one car at a time.
6- Make sure that GPL has been patched properly. If you are running XP, patch to v.1.2.0.1 at least. If you have the Sold-Out Software CD,
use the patches on the CD in the Patches folder. Apply the patches in the order: 1) patch to v.1.2.0.1, 2), D3D patch, 3) fast CPU fix (v.1.2.0.2).
8- There is another program running which interrupts GPL - virus checker, e-mail etc. Use EndItAll (EndItAll2 does work with Windows XP)
or ctrl-alt-del to close all other programs.
9- GPL is sensitive to IRQ sharing problems. Look in system > properties > hardware > device manager > view > resources by connection > IRQ list to
see if your graphics, sound or network cards share an IRQ number with any other hardware.
10- Upgrade your video card drivers.
11- Upgrade to the latest DirectX version.
12- Changing to Windows XP or upgrading your computer helps.
13- One GPLEA Lotus version needs to have all textures in the mirrors on.
14- It might be a problem with the refresh rate when the resolution changes going to the menus (always at 640x480). HZtool might help.

Controller issues


Solution for using a gameport controller for GPL under Windows XP
(thanks to M Needforspeed for this "For me it was a survival kit, as even with 250 MHz
potentiometers (see a thread on that subject) my wheel didn t run with USB/gameport adaptor)
1- Go to control panel > Game controllers.
2- Click on add > custom.
3- Select wheel or race car controller > 3 axis > Rudder/Pedals > # buttons on your wheel (4 max). Don t check Z axis, it doesn't run.
4- Name your game controller.
5- Click on OK to validate your choice.
6- In the next window, verify controller is connected.
7- Click on properties > parameters > settings.
8- Axis X: steering wheel setting > axis Y: throttle settings > Rudder: brakes settings.
9- Go to test. The rudder bar must be full red.
NOTE: on some wheels, the Z axis may work, as this setting is for my SPEEDWAY wheel. In this case check it on step #7 and uncheck Rudder/Pedals.
Go inside GPL, you should now have the three axis parameters in black, ready for setting.

Calibration - Controller axis missing?
First - Delete the control.cfg file in your player folder
Second - When you start GPL, another control.cfg will be created.
Third - In the Calibration window run the axes through their ranges.
Fourth - Only now can you assign the axes in the GPL game controllers window.

Controller pedals won't go to split axis and three axes actually appear for the throttle and brake
See this thread > Post #6. Download DXTweak2 and use it to "fudge" the combined axis of the
pedals, by setting both max and min values to 0. Looking at the input screen then shows the Direct Input from the combined axis sitting all the
way to the right, whereas the separate axes work as normal. Thanks to Tim Nightingale. You might need to use lower values than 0.

Multiplayer, VROC, iGOR and the Bandwidth patch.


GPL crashes when trying to join a race
1- Files have gone missing from the layout folder relating to multiplayer screens. Copy all the original layout files from the GPL CD into this folder.

Starting VROC, a message about riched20.dll comes up.
1- Simply delete riched20.dll from the winvroc folder.

All red flagged tracks in VROC. 1- Reset the path to GPL. Even if it looks right, direct it to a different folder, then back to sierra\gpl. This is a bug in VROC.

Can I race on VROC with a dial-up connection?
1-Yes. Speed is less important than a stable or consistent connection. Faster connections are better, though. Satellite and wireless
connections are not good due to variability of the signal.

Can't see a racelist in iGOR or VROC
1- Make sure that you have the right IP address listed. As of Dec 2005 (it may change from time to time - ask in the #gpl chat at iGOR or VROC)
you should have the following:
In the iGOR.ini it's IP = gplrank.info
In the VROC.ini it's Address=213.84.59.34
2- Use Bernd Nowak's utility, a bug fix for people that are not seeing a racelist, here

Bandwidth mismatch error or can't join a race 1- Get the BWpatch here
2- Run bwpatch.exe from inside of the gpl folder and a DOS box comes up
3- Type 1 > enter x > enter so that you have "more cars patch : applied"
4- Put the following values in the core.ini [ communications ] section:
net_mdm_client_send_every = 3
net_mdm_client_send_size = 84
net_mdm_server_send_every = 3
net_mdm_server_send_size = 384

**The iGOR or VROC #gpl chat room is a great source of information. Just ask any question there.**

Sound - Sound card:

General tips
1- A thing that has helped is, in control panel > Sounds and Audio Devices > Audio tab > Advanced > change the playback device settings to
speakers or headphones or mono or stereo and see if that helps. You might also play around with the sample rate conversion quality slider.
2-In the same window try reducing the "Hardware Acceleration" a notch or two.
3-If you're having sound troubles, sometimes newer or older drivers can help.
4-Try using a different in-game screen resolution. Strangely, this fixed sound corruption for me.
5-Older Realtek (onboard sound chip) drivers, including the A3.29 drivers that GPLers seem to favour, can be found at here
6-Thanks to ducwolf - this seems to be the fix for SB Live/XP problems but possibly at the cost of reducing multitasking ability.
Just remember your original settings and give it a try. For "Noisy sound playback on PCs using a VIA chipset and nVidia graphic card" for Windows
NT, 2000 and XP, see here.
7-Check out this thread for a simple BIOS setting fix Thread
8-According to Toni Mau it seems that the A3.52 drivers for the AC97 sound chips work best (March 2006).
9-According to PTRACER, the 3.29 drivers work well, found here
10-According to Mr. Hitman there are drivers for the ALC850 chipset (nForce mobo's only) which solve sound issues.
11-According to Rodolfo there's an article about crackling sound with Creative X-FI cards.
12-Here's an article on changing the PCI Latency for better sound.
13-Here you'll find a PCI Latency or Disable Turbo Mode patch for SB sound cards.
14-Stefan Roess reports HERE that there's a very interesting utility for all audio devices which might help some sound issues.

Sound goes funny after a collision.
1- Upgrade to the latest drivers for your sound card.
2- From Albher: "The older SB drivers version 3509.2 are known to help a great bit. I use them by myself without problems on WinXP and before that
in Win2K. Do a web search for "SBLiveXPDrvUpdate.exe". Take care that all sounds are sampled to 22050Hz, using Goldwave
(found here) or else you'll get distortion.
With that driver, you can again select full acceleration in DirectX (run dxdiag.exe)."
3- see here
4- see here
5- You can do a Shift+R with the engine at a certain rpm (you'll have to experiment) to clear it up.
6- jumi2 reports "GOOD drivers (for AC97 onboard AND gpl) :ver: A3.29 and called : 5.10.0.3990 and released: 06.09.2002 and any other drivers
not good in GPL"
7- According to Toni Mau it seems that the A3.52 drivers for the AC97 sound chips work best (March 2006).

Sound problems with Windows XP and SoundBlaster Live sound cards.
1- SB Live cards and XP are a problem, unless new drivers can cure it. Usually a new (different) card is needed. It has been reported that the
newest drivers help.
2- See Sound Blaster driver d/l
3- Go to the Audio Properties > Audio > advanced > performance'. You should see a Hardware Acceleration slider. Bring it down a few notches until it
says 'Basic Acceleration Only'.
4- see # 2, 3 and 4 just above. One of these should help, hopefully.
5- scirocco790 reports that drivers for the SB Live found at here helped the sound problems with XP and the SB Live card. See the thread here

Sound problems with SoundBlaster Audigy sound cards.
1- There's a thread HERE where it's pointed out that you might need to disable "Turbo Mode" with the Audigy card and how to do it.
That mode can cause sound problems.

Installation - Patches


Computer asks for the CD or says that it's an invalid CD when trying to install or run GPL even though it is in the CD drive.
1- If the problem is after installing, make sure that the v.1.2.0.1, D3D and fast CPU fix patches are applied properly.
2- If you have more than one CD or DVD/CD drive, try all of them.
3- You get the invalid CD error sometimes when having more than one CD-ROM drive. It's important that you install GPL from your first CD-ROM and the
drive letter follows immediately after your last hard disk partition.
Example: You have two hard disks, C: and D:. Then GPL should be installed from CD-ROM (or CD-RW?) E:
4- If you have 2 DVD/CD units try disconnecting or disabling one of them while you install gpl.

Copying GPL directly off the CD (without running the installer)
1- Copy all folders from the CD to the hard drive under a folder called Sierra\gpl
2- Copy all files not in folders on the CD into the main gpl folder. Many of these aren't necessary if you can figure out which they are,
but to be on the safe side, copy them all over.
3- You must create new (empty) folders gpl\exports and gpl\players

GPL original demo will not run.
1- Make sure that you have applied the patches from the Papyrus downloads site, v.1.2.0.1, D3D, fast CPU, although some have reported that the demo
can't be patched. Buy the game through Sold-Out Software or elsewhere over the web it is a true bargain.

2- The 2004 GPL Demo here is fully patched and the cars are graphically upgraded, although it only comes with one track, Watkins Glen.
It doesn't need any further patches to run.

Error messages while installing.
1- Activemovie and wininet.dll are not required to be installed, just ignore or pass it by.
2- If you use anything other than a VooDoo card (3dfx rasterizer) for graphics, choose software at first, then apply the D3D and/or OpenGL
patch after installation. Otherwise you will be told "glide2x.dll and redline.dll is missing"
3- Message: "C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications.
Choose Close to terminate the application."
4-You might have one of the following files corrupted or missing due to a Windows upgrade.
Autoexec.nt - Config.nt - Command.com
See autoexec.nt
Also see Microsoft's bulletin

Other - Miscellaneous:


Trouble accessing players in the player selection menu
1- Try to not use any punctuation or spaces, although usually an underscore __ is OK.
2- Make sure that all player names use recognizable characters. It might be that another unrecognizable player name is causing a properly named
player to be inaccessible.
The player name is corrupted or inaccessible
The simplest solution:
1) Copy that player folder to another location
2) Go into GPL and delete that player
3) Re-create the player with the same name.
4) Copy in the important files from the backup like the setups, PB times from the player.ini (this is probably the file with the errors however)
and control.cfg (or just re calibrate the controls in-game).
Runar Bjornstad reports that there's some kind of bug cropping up sometimes:
QUOTE=Runar BjornstadJust had a similar problem and there is a bug that messes up your player.
Delete all folder in Players except the one with the right name.
In app.ini set the name there: (example for RB)
[ Player ]
lastPlayer = B__R
Then make sure it's correct in player.ini:
[ Personal Information ]
firstName = R ; first name of the player
lastName = B ; last name of the player
And the same for plac65.ini:
[ Personal Information ]
firstName = R ; first name of the player
lastName = B ; last name of the player
And another solution by Henrik Brodin:quote
1. I removed everything
2. reinstalled, all-in-one-patch (still didn't work)
3. Turned on indexing and ran CROA again, which now reported about 100 read-only files.
4. Voila, the driver was saved, everything worked, and I could drop my old player back in the folder and he was then available again.

In GPL menus, the mouse is hard to control.
1- This seems to be due to improperly installed graphics card drivers. Uninstall and reinstall according to the instructions from the card manufacturer.
Numbers are missing from cars at the start of a race against the AI.
1- You must wait until the red button appears before going to the grid at the start of a race or all the car graphics won't get loaded.
2- The driver.ini file must match the carset since some carsets assign graphics to drivers of that particualr year.

Looking for information on How-to, new tracks, utilities for GPL?
1- GPL the Addons has most utilities and how-to info about things like changing the colours of the gauge needles, driving views, AI speed adjusting and
many other things. A list of all track graphic updates, tracks in progress and more is there, too. 2- The [URL=http://trackdb.d2g.com/?]GPL Track Database[/URL] has all tracks that have been made for GPL.

Error message 'Cannot find Glide.dll and redline.dll'
1- In your GPL Folder there are two dlls which can be deleted: rast3dfx.dll and renddll.dll. Then GPL won't ask any more for the other dlls.

Error message regarding 'ddhelp'
1- Upgrade your Directx software form Microsoft.
2- Upgrade to the latest drivers for your video card.
3- Use EndItAll or ctrl-alt-del to close all other programs.
4- Excell has reported that this might be related to a faulty stick of RAM or the socket that it's in. Try moving it or swapping in another stick.
see here

Can I race GPL with a laptop?
1- Probably on newer ones, but video card and Directx compatibility issues might cause problems, especially with older laptops.
2- In the BIOS, disable the speedstep feature.
3- In the BIOS, fully disable all power managment
4- Someone devised this solution: The final solution was to write a simple C program containing an endless loop, run that program, set the priority
to 'Low' and then run GPL. (and don't forget to close the program after you ended GPL) The endless loop makes the CPU run fulltime, but the low
priority means that it does not interfere with GPL. 5-See also above in post 2 stuttering problems and variable speeds.

Where can I buy GPL?
1- Try either E-bay, Amazon or Sold-Out Software. There are many other places to buy over the web, just do a search for Grand Prix Legends
and price or Soldout. You are not likely to find it in a store.
2- Check out the Where to buy GPL thread.

Problem's with Vista


User Account Control (UAC) Vista requires you run in standard user privileges mode instead of as administrator with full administrative
rights which keeps you from doing some operations like adding GEM and other utilities.
So disable UAC in Vista to run GPL. See http://www.mydigitallife.info/2006/12/19/t...-windows-vista/

From mikevar:
QUOTE
go to "control panel" > "user account", select your User account.
Now disable "User account control"
Now you can install GEM.

Vista tells you that isn't good for pc protection... but with this enabled
you can't install or dis-install some applications..

Menu screens not visible
There have been a couple of reports that the pbf files that make up the background images
of the menus can't be seen when starting up GPL. It appears that this only happens when
anti aliasing is enabled, so try running GPL with AA off. A solution for this
hasn't been found yet, but it sounds like a graphics driver issue.

Sound recorder in vista will not allow you to adjust sound levels.
Thanks to Stefan S
To get the old recorder to work on Vista, do the following: 1. Copy the %SystemRoot%\System32\sndrec32.exe file from a Windows XP
or Windows 2003 computer that is the same edition as your
computer (i.e. 32-bit or 64-bit) to your Vista machine.
2. Right-Click the file and choose Run as Administrator. (This is required so that it can write one-time registry entries).
3. Enjoy — from now on you can just double-click that icon and the old app will work!

Problem showing ping and accessibility flags in VistaAccording to zempaolin:
"after the installation of Windows Vista Service Pack 1, VROC is able to ping servers on racelist and I get green flags again."
