Hello @opal1974, err:module:import_dll Library api-ms-win-shcore-stream-winrt-l1-1-0.dll (which is needed by L"Z:\\home\\user\\.local\\share\\Steam\\steamapps\\common\\Cotton Reboot\\cotton_reboot.exe") not found in your log points towards needing at least https://source.winehq.org/git/wine.git/commit/7f7fdd6c8657ebe4079c9f959bbfba508a2d1680, which is in wine 6.6 and newer.

After that is err:module:import_dll Library vccorlib140.DLL (which is needed by L"Z:\\home\\user\\.local\\share\\Steam\\steamapps\\common\\Cotton Reboot\\cotton_reboot.exe") not found which will need more developer attention.

I used Winetricks to add the missing vccorlib140.DLL via installing the VCRUN2019 package, and I now can see the title screen. The game then crashes with the error given in the log (perhaps a stub is needed from Wine?):

seems to be something to do with the error: Unhandled exception: unimplemented function api-ms-win-shcore-stream-winrt-l1-1-0.dllCreateRandomAccessStreamOnFile called in 64-bit code (0x0000000170032048).

Has anyone had any luck with this? When I try with SteamTinkerLaunch to run with VCrun2017 I get a splash screen about how naughty it is download things illegally and then it crashes to desktop. Is Proton triggering some kind of false flag anti-piracy thing?

[jesus-ramos]

The crash is due to a stub for CreateRandomAccessStreamOnFile. Creating a stub that just returns nothing useful just hangs on a black screen at another stub for MFCreateMFByteStreamOnStreamEx.

It's kind of a shame that they didn't use SHCreateStreamOnFileEx() and MFCreateMFByteStreamOnStream() to get the MFByteStream since the RandomAccessStream wasn't used for anything else and those functions were actually implemented.

I did get the game working (other than the publisher intro video) by loading my own code in and overwriting the stubbed functions to basically call those functions. Not useful for implementing Proton functionality but it's here if you want to play with it.
