Can't inject on Proton (7.0-4) any more

[Dregu]

Worked fine when Proton 7 was released, worked fine even with Proton 6.3. Now it doesn't work on any Proton version when running from Steam with launch options --launch_game .., and this feature was specifically added for Proton support and well tested to work back then... I don't know what happened.

Wine-7.14 + DXVK + GoldBerg Emulator still works fine.

Prepending PROTON_LOG=1 to the Launch Options for both Overlunky and Spelunky 2, the log for Overlunky shows that 4433.564:012c:0130:err:module:import_dll Library MSVCP140_CODECVT_IDS.dll (which is needed by L"Z:\\home\\sean\\.local\\share\\Steam\\steamapps\\common\\Spelunky 2\\Overlunky\\injected.dll") not found. (This is with Overlunky in a subfolder of Spelunky 2, like you have.)

Moving the contents of Overlunky/ up directly into the Spelunky 2 directory and changing the Steam shortcut and launch options to PROTON_LOG=1 %command% --launch_game ., Overlunky.exe now launches Spelunky 2 and seems to inject the dll. A small text displaying Overlunky 0072402 shows at the bottom of the game window, but I don't see the overlay, and none of the shortcut keys (function keys, etc.) from the readme seem to do anything. I don't have an overlunky.ini file though, and I'm not sure whether Overlunky has defaults.

Edit: I launched with wine, saved the Overlunky settings, and it created an overlunky.ini file. Launching from Steam with Proton still doesn't show the Overlunky menu. It's not disabling game saving either; I did a quick run, and when I re-opened Spelunky by itself, it had been saved to the Player Profile.

I've disabled the Steam in-game overlay globally, but still [debug] Steam detected, hooking Steam Overlay..., whereas launching it with wine, [debug] No Steam Overlay detected, hooking D3D... (Note that I'm not using GoldBerg Emulator in any tests.)

The injection method was changed in #283 when using the --launch_game parameter, mainly to fix a lot of linux and proton problems. Also symlinking the missing DLLs to the Overlunky directory may help. I fixed my own issues with these, but Linux is a jungle.
