ICR2 FFB - Force Feedback App!

[jxeboy]

So, no amount of fudging the keymapper/dosbox/dosbox staging/HIDhide will get me to the point where I can use my pedals and wheel in ICR2 without vJoy/Joystick Gremlin And when I use that combo, I get no FFB. Still nothing useful in the log files either, just the same output in the console that I posted earlier.

There's always one  

I did some quick reading about vjoy and it seems it might not accept normal direct input commands.

What joystick type are you using in your dosbox.conf file? If you have two controllers you must use the '2axis' option. Maybe you already have that set but its worth a try

I got it working thanks to Menkaura. He suggested (via PM - his account hasn't been activated yet) that I do all the HIDhide/vJoy/Joystick Gremlin stuff as before, but remove the wheelbase axis from the Joystick Gremlin remapping profile.

Thank you so much for your assistance Jake. And thank you so much for the FFB patch; it's unreal that guys like you are still making truly incredible improvements to a 30 year old game.

PS: A friend of mine has forked it and wants to have a look at creating a proper UI for it to remove the need for editing .ini files. I can put you in touch if you want.

Glad you were able to get it working! Interesting to hear someone might work on a UI, i was thinking about doing that at some point.


I've released a new version today with some updated math thanks to Niels Heusinkveld. The method he proposed makes the calculation overall much more simple and it feels even better now without the need to do a lot of extra calculations for smoothing. 

v0.8.8 Beta: https://github.com/gplaps/ICR2FFB/releas...Beta-0.8.8

We've also located some longitudinal force values that might be able to be incorporated to add some forces related to braking or acceleration. Perhaps ill get into that next week!

As I've already commented your video on youtube: Thank you so much! I can't believe how you and the other guys have lifted this 30 year old sim to new heights in the last months. It's still my favourite sim I always come back to (I guess it's part nostalgia, part accessibility). And now we have Rendition graphics and FFB - unbelievable!

In general, I'm not that great fan of FFB. Some games didn't get it right, others aren't that compatible with older FFB wheels like mine, the effects are often fuzzy and not really helpful. 

But your FFB really helps the driving! I can save the car now from spinning... A totally new experience in this game! (The higher frame rate of the rendition version also helps a lot, it gives you more time)

I had to turn up the force strength setting in the ini file to 75% for my Logitech Momo Racing Black. The wheel itself is on 100% (standard) in the Logitech Profiler.

Some minor things only (I tested yesterday with app version 0.8):
- grass/dirt effect very weak
- no wall bounce/crash effect (not that I'd need that  )

And one major thing:
- still some snap oversteering without warning at some points. I guess it's the game itself or some track settings (very low grip?), and not your app's fault. But you or others maybe could test it.

My nightmare track in this regard was and still is Laguna Seca - original or "New" (Rendition version): e.g. at the corkscrew and at the last corner. I never can finish any races there because of that snap oversteering which comes out of nowhere, after some laps in, with warmed up tires and full tank, standard "ace" setup.

Hi Jake, great work, very impressive. I have FFB working with the dos version of the game but not with the rendition version. I’am using a Thrustmaster T150. Any clue?

In the config file:
Version" - this can either be "REND32A" for rendition or "DOS4G" for regular dos (sorry no windy yet)

and you need the DOS32A bound version of ICR2. It can be found here:

https://nirvtek.com/downloads/ICR2.DOS32...0Buffer.7z

I can't remember the MD5 checksum of the archive. It has both Cart.exe and indycar.exe which are the same game just with different branding.

FlyingEagle (gpl?), the default ace.stg setup is not that good. Having a great setup makes a huge difference to driving consistency and lap times. I'm no good at making setups but there's good options out there. The old Achim setups are great. The best one I've found for Laguna is the Tarcisio Laguna setup from the world records page. See tab up the top. Also, look out for Samsepi's setups, also great.

I think this can happen even in real life, not an issue with the game or FFB. Let me explain it. Through the steering wheel you only feel forces / torque from the front wheels, nothing directly from the rear. So if your rear tires happen to lose grip why your fronts still stick, there is no warning through the steering wheel.

I think Alonso said sometimes about steering wheel feedback, that when he turns in, he expects either the front or rear wheels eventually starting to lose grip. If he feels the steering wheel easing (while still turning), it is the front, and the car understeers. If he does not feel, it will be the rear losing grip, so he prepares to catch the first minor oversteering. Of course, in a real car you feel oversteering not just through vision, but also through our body, which makes it easier to act in time.

And Corkscrew is a notorious place for oversteering, because when the car goes downhill, weight shifts to the front, giving less rear grip. And I think this effect is modeled in ICR2. So if you set your car for being nice there, it will badly understeer in other parts of the track. Try to finsih all braking (including trail braking) before the track goes downhill. Or change your ARB settings in the straight leading to Corkscrew, and change back after it (more front or less rear ARB moves the balance towards understeer).

What you are describing is much more pronounced in gp2. It's probably the thing I like the least about gp2. I feel it is too over exaggerated.

I use a logitech driving force gt wheel/pedal set (I actually have about 5 of them since I collect spares). I have not used this ffb yet but maybe I will if it's something we can use in both gp2 and icr2 (these are the only games I play)

I tried the exe you recommend Sharangad , but still no FFB. Thanks for the suggestion.
