WRC 9

[xpander69]

Name of the game: World Rally Championship 9
Steam ID: No Steam
Game Type (native/proton/wine): Wine
Proton/Wine version: 5.18, 5.20, 5.22, 6.0rc1, 6.0rc3, 6.0rc6
Wheel Model: Logitech G920
Distribution: Arch Linux
Kernel version: 5.10.6

Force Feedback present: YES, but only Constant force. No other forces work :(

Game detects Logitech G920 profile, buttons seems to work, no force feedback settings can be adjusted. Game reports that wheel with haptic feedback needed.

tried all combinations of the ffbtools to try to fix it, with no joy.
Log: with features-hack, update fix and throttling
wrcffb.txt-20210113195118.log

i doubt anything can be done with it with ffbtools though. from what i gather on the forums is that people say that G-Hub has to run to detect the wheel properly. G-Hub is some windows software i guess?

I guess you've driven the car in the game to get this log. It just sets an autocenter force. I guess that's what you mean in the description of the FFB you get.

The problem will probably lie in Wine. Maybe it's not correctly detecting the wheel or its capabilities the way the game queries it.

yeah i drove one split on a finland track... yeah i guessed those tools wont help here. I guess you can close this issue then. Just wanted to check in if maybe someone knows how to make it work :(
any idea how i could debug this?
WINEDEBUG=+dinput or what are the wheels using? xinput?

[berarma]

I'll leave it open. This project is aimed at helping solve any FFB related problem since these are usually ignored in most places. No problem on discussing here about debugging and trying to get this issue fixed somewhere else.

any idea how i could debug this?
WINEDEBUG=+dinput or what are the wheels using? xinput?

I think that would be enough but Proton developers usually recommend WINEDEBUG=+dinput,+plugplay,+hid,+tid.

debug.log
this is what i got... i guess i should report this to wine devs or proton?..though this game is not on Steam, previous game is, which i think uses same engine.

edit:

i think this line: 0024:trace:dinput:_dump_DIDEVCAPS dwDevType: 00010214 DI8DEVTYPE_JOYSTICK (HID)

should be DI8DEVTYPE_DRIVING to make it known for this game. according to older game: ValveSoftware/Proton#1183 (comment)

It can be reported to the Wine bug tracker.

You could have found the source of the problem. Which SDL version is using your Wine install?

hmm how do i check which one wine is using?... i have extra/sdl2 2.0.14-1 [installed] and have built my wine versions myself, so i guess it builds with that?

[berarma]

Probably. You can use the ldd command with the wine executable to see which libraries is it linked to.

[xpander69]

uhh doesn't look like they are hooked at all... same with system wine

I was wrong. It's not the main executable that links, it's the libraries dinput.dll.so and dinput8.dll.so.

[xpander69]

those do not show libsdl mentioned either... what i also found is here:
https://www.reddit.com/r/WRCTheGame/comments/il9820/wrc9_possible_issues_and_fixes/

under Your G25/G27/G29/G920 does not have FFB settings?

some weird registry hack to make it detectable, but under wine theres no such location even.
is it possible to fake this kind of thing?

[berarma]

The files should be available in the game's prefix directory.

Maybe your wine install doesn't use SDL. That would explain the issue. Can you try running the game with proton? Proton is just a modified Wine. There must be a guide somewhere to do it.

[xpander69]

with proton (5.0, 5.13 and experimental) it just crashes on startup. or i dont know how to hook it correctly into proton. i just added the game exe as the non-steam application and made sure the paths are correct.

also Snowrunner and LFS have FFB working just fine with those wine versions. I will try some more things.. thanks for the input.

[kodatarule]

I can confirm the issue as well both on my G29 and Formula Force EX. It seems that it recognizes it as a joystick instead of a wheel thus leaving all of the FFB locked.
EDIT: With Proton it just straight up crashes.

[berarma]

OK, I think that's the issue, I've just checked in the code and it seems so. Wine has two backends for dinput, one uses the Linux evdev interface, the other one uses SDL. Evdev has no way to query the joystick type, SDL has. You should look for a way to build Wine using SDL. Proton uses SDL by default, Wine maybe not.

[xpander69]

yeah managed to get it to run with proton-GE 5.21
it now shows nicely its using SDL, the game shows all the options unlocked ingame now also, but vibrations still dont work. so no road bumps or anything are felt.. and it seems way beyond my knowledge to figure it out sadly
