Howto have SimHub and Fanatec leds working in ACC

[mferraci]

Hi all,
After several hours of research, I finally made SimHub working with ACC, with leds and screen on my fanatec formula v2.5.

**0. Backup your ACC prefix
Save a copy of your prefix in case something go wrong

1. Pre-requisites

• Build gotzl fanatec driver from latest master (https://github.com/gotzl/hid-fanatecff/tree/master) and install following instructions
• Build Proton from sources with multi TLC patch (https://gist.github.com/gotzl/6e90dd6852bbc48cd85e006250586b16) or get a compiled version (check the link in the readme)
• Install Steam tinker launch https://github.com/sonic2kk/steamtinkerlaunch

2. Prepare the prefix
SimHub needs dotnet48 to work. This somehow breaks dependencies required by FanatecSDK and while ACC still works correctly, leds of Fanatec wheels shutdown. You need to install

• In steam, force compatibility and select your Proton version compiled with multi TLC patch
• Run at least once ACC to create proton prefix
• Run wineprefix on your ACC prefix
• Run WINEPREFIX=[path.to.your.steam.library]/steamapps/compatdata/805550/pfx winetricks
• Select Default wineprefix and then Install a Windows DLL or component
• Select dotnet45 and dotnet48. You will have several warnings

3. Install Simhub in your prefix

• Download last SimHub release (https://www.simhubdash.com/download-2/) & Unzip
• Run WINEPREFIX=[path.to.your.steam.library]/steamapps/compatdata/805550/pfx winetricks
• Select default wineprefix then Run an arbitrary executable and select SimHub install exe file
• During install, unselect install .net and C++ redist and usb display drivers, then proceed with install

4. Start ACC & SimHub with steamTinkerLaunch

• Go in steam and select SteamTinkerLaunch in force compatibility
• Start the game and click on "Main Menu" on the SteamTinkerLaunch pop-up (you need to be fast)
• Click on Game Menu
• Select "Use custom command", "fork custom command" and "inject custom command"
• In field "Custom command" select SimHubWPF.exe from your ACC prefix ([path.to.your.steam.library]/steamapps/compatdata/805550/pfx/drive_c/Program Files (x86)/SimHub/)
• In proton options/proton version, select the proton compiled with multi TLC patch
• Save and play

Now everything works perfectly. Sceen and leds are working perfectly on fanatec wheel. I can use Simhub app on my phone to get a very nice dashboard (I use Lovely SimHub Dashboard).
