Formula 1 Simulator with GP1

[Eduardo Fernandes]

Good morning,
Today I'm starting a brand new project on my internship: Build a 1991 based car simulator using GP1

But I need some help setting things up, so I might as well talk with the experts on the field. I don't have a huge amount of experience with Grand Prix 1, but I've been thinkering with it and I love the possibilities it gives.

I'll be posting pictures of the progress I do with this project. The car I'll build will use recicled materials at first, saving money wherever possible. I'm doing this as my curricular internship project and it has been aproved by my superiors.

Here's what I need:
- Help setting up my Logitech Force EX with Grand Prix 1, as I never used a wheel on the game. I tend to run GP1 on DosBox but I can also run it on Windows XP as a batch with cmd. I'm confortable with cmd but I have no idea how to setup the wheel on it.

If you have any tips on it, I'll be thankful. As soon as I make the game compatible with the wheel, I'll just have to build the simulator around it.

Hey Eduardo,

That sounds like a cool project.

I think it will be much easier to set up the wheel through DOSBox.

You can use the information listed in this post as the starting point for setting up the wheel in DOSBox and inside F1GP

If you really wanted to use the wheel under Windows XP, first you would need to have the wheel drivers that work on Windows XP. After that, I think you would need a joystick emulator like vJoy to map the wheel to a virtual joystick, that the game would recognize.

Cheers,

Hrvoje

Great, thanks!

I totally prefer working inside DOSBox as the sound seems to not work properly when I use Windows XP itself for some reason. And it kinda looks cool showing the mounting commands and accessing the game trough the DOSBox Command line. I managed to impress my supervisor showing him how to open this 1992 game (4 years older than myself) :P

Because I'm currently hurt and in pain, I'll be at home testing the wheel today. I'm also taking measurments to build a wooden cockpit of a fantasy car for being displayed. It will be based on the game model for simplicity.

[Eduardo Fernandes]

Ok, here I am with an update. I've been working on the 3D model on a legacy piece of software, this is what I've done so far.

I'm expecting to also do a force feedback test today as well as a DosBox wheel test

Hey Eduardo,

It looks like you're making good progress.

Btw, you can find a 3D car model inspired by F1GP in this thread:

[Eduardo Fernandes]

Wow that model looks pretty cool, but I'm unsure how can I use it.
The main reasons why I'm making the model I am are:
- to impress my supervisors

- so I can have accurate measures for the wooden structure

I probably won't need the 3D movel for anything else so far, but maybe in the future I'll find more uses for it.

Hey, 

It's a very interesting idea and project :) It'll be fascinating to see how it all works in the end :) 

Regards, 

Barrie

Thanks Barrie, I hope I can get started on building the physical model soon.

I've completed the Airbox, Sidepods and I'm working on the rear wing of the 3D model now.

So, my progress today was all about testing the wheel and software, but I've encountered a few issues I may need help with.

The wheel (Logitech Force EX) gets detected wheel and it's easy to do the mapping, but I've found something that Ted Meat may have encountered as well. I've been doing plenty of laps and thinkering with settings but I wasn't able to find a perfect solution yet.

- If I use linear steering, I get better feeling then driving but the car is very hard to control at high speeds and in the straights, so I crash when I try to take fast corners.

- If I use non-linear steering, I need to ajust the steering lock so I can take the slowest hairpins, but then I get into this weird situation where the car is stable on the straight, but it's very hard to turn into corners, because the steering goes from not turning at all to turning a lot in a very precise angle. To adapt to this I have to try to hacksaw on the wheel, to be able to go fast into corners without losing stability, like Nascar drivers do, but it requires a lot of effort and I probably lose time. It's better than to crash on the straights, but it's not good enough.

I wanted to ask if anyone knows any solutions to this. I tryed to use linear steering but I don't have any deadzone settings on my wheel profiler, and the game doesn't have any as well.

Hey Eduardo,

I recommend you try using a different version of DOSBox, in particular DOSBox ECE:

https://dosboxece.yesterplay.net/

DOSBox ECE has a joystick deadzone patch, so you can adjust the wheel deadzone through DOSBox.

Ted also mentioned that using a different version of DOSBox (not sure if ECE or Daum) helped him with playing GP2, as it provides better steering resolution.

I'm not sure if this would also help in F1GP, but you can try.

Cheers,

Hrvoje

[Eduardo Fernandes]

Yes, Ted recommended using SVM-Daum, but for some reason I have issues that I don't have with DosBOX, and he recommended Daum for GP2 to deal with the game running too fast, and surprisingly I don't have that issue on DosBox (I've had that issue before with The Elder Scrolls, so I'm keeping SVM-Daum to test that).
The main issue I had with SVM-Daum was when calibrating the wheel, it wouldn't detect it properly, and it would always be randomly calibrated. Surprisingly, DOSBox doesn't have that issue. Hopefully I'll recreate and record that issue soon.

I'll give a try to that version, DOSBox ECE, I'll be testing it this afternoon.

Hi Eduardo.

Ted Meat switched to DOSBox ECE earlier this year.

I have had a lot of problems with getting GP1 and GP2 to run properly.
But recently I myself switched to DOSBox ECE and now both games run very well.

For GP1 I only change two settings in dosbox.conf :
cycles = 20000

deadzone = 0

In the game I use the Control settings which you can see attached:

Linear steering

Max Lock = 12° (game standard value)

My wheel is a Thrustmaster T150 Pro.

I have set the Rotation angle to 360° and the pedals to combined.

With this setup the car is stable to drive at high speeds AND easy to manoeuvre through Monaco hairpin.

From searching Google I see your wheel has a Rotation angle of 200°.

In this case I would consider setting Max Lock to a lower value to get better stability at high speed.

But still have Max Lock high enough to get through Monaco hairpin.

Perhaps Max Lock = 10° will be a good compromise.

I hope this information will help you with your project.

Best wishes from Demark :)

[Eduardo Fernandes]

Danish Racer, that's amazing :D What a great present for my 24th birthday :D I'm gonna give it a try this afternoon. I haven't even drove in Monaco but I struggled with the Magny-Cours's Adelaide Hairpin with 12 degrees of lock.

I managed to have good slow speed performance with 15 or 18 degrees max lock, but high speed stability struggled. Nevertheless, I'll test this out and I'll provide feedback. Currently my wheel and DOS Machine are on separate buildings, but I'll see if I can setup everything on a fresh machine as well.
Looking forward to try this :D it has been great fun.

[Eduardo Fernandes]

I wanted to ask, Danish Racer why deadzone = 0?

[Michael Gott]

Apologies for the hijack of this thread. But I have GP1 & GP2 both on Dosbox reloaded. Not yet hooked up my Logitech G27 to play them. I would love to use ECE Dosbox but I simply can't and don't understand the mounting process. I've followed numerous instruction threads and YT videos, but I just can't get the games to mount. I just get countless error after error. I've followed the tutorials word for word but still no joy. There's something I'm just not doing or understanding and I'm confused and just don't understand.

Wish I could use and do it with ECE or similiar, rather than D-Fend as I've heard ECE is good.

Thanks 😬😠☹️😭

I'm also wanting to test if this wheel setup will work on Papyrus's Indianapolis 500: The Simulation. It would be lovely to have a joystick configuration working for both sims.

[Eduardo Fernandes]

Michael Gott, it's great to hear from you. Are you trying to mount from what format? ISO?
I haven't tried ECE yet but I have a lot of experience with mounting images, so I'll test and see if I can help you out as well.

[Michael Gott]

Hi Eduardo

I have both the original discs and Iso versions. I find D-fend easy because it mounts it for you, but normal Dosbox, ECE or whatever, just leaves me banging my head against the wall. It's so frustrating that I can't do it as I'm usually pretty well technically versed. So I can't understand what I'm doing wrong?

Any help would be appreciated. Thank you 👍

Michael,

There are a few ways to mount discs and ISO images in DOSBox. 

This works both in the original DOSBox and in DOSBox ECE.

1) Mount disc from the CD ROM drive E:\ on the computer, to drive D: in DOSBox:

MOUNT D E:\ -t cdrom

2) Mount ISO image located at C:\IsoImage.iso to drive D: in DOSBox:

IMGMOUNT D C:\IsoImage.iso -t iso

3) Extract the contents of the ISO image to the hard drive at C:\IsoImageFolder, and mount it to drive D: in DOSBox:

MOUNT D C:\IsoImageFolder

Here you can find the full mounting instructions:

Cheers,

Hrvoje

Hi Eduardo.

First of all, happy 24th birthday :)

I use deadzone = 0 because Ted Meat does so in this blog post:
https://tedmeat.com/2020/07/NASCAR-Racing-by-Papyrus-1993-Play-with-a-modern-racing-wheel

I tried GP1 with deadzone = 10 (Standard value for DOSBox ECE) but the car was difficult to control at high speeds.

So I tried deadzone = 0 and the steering felt much better.

I learn a lot from Ted. He was my inspiration to buy my wheel and play GP1 and GP2 with it.

[Michael Gott]

Thanks all for the info on mounting GP1 & 2 on Dosbox. Much appreciated!

I will give it a go and another try again.

Thank you all 👍

Danish Racer, thanks and I'll give that a try. Using deadzone = 0 kinda feels not very intuitive for me, but I'll give it a try.
Also, I was gonna recommend the IMGMOUNT command as well, I've found it to be very useful.
