[Feature Request] Allow customized game launch path

[KrisCris]

This would make it possible to directly launch custom launchers like the one for elden ring seamless coop mod. https://www.nexusmods.com/eldenring/mods/510?tab=description

ModEngine needs to be in control of creating the game process for injection to work, so making this work is tricky. However, Seamless Coop only requires an external DLL to be loaded. You can do that by editing your modengine configuration like this:

[modengine]
external_dll_discovery = true
external_dlls = ["elden_ring_seamless_coop.dll"]

Leaving this open as a tracker for UX of using external launchers.

Nice! So where should I put the dll to, do I need to specify a path to it?

Update: I got the dll loaded by putting it in the root folder of modengine.

Btw, this might be off topic but... is there a way to tell if a mod is successfully loaded?

Kind of, but not in a supported way. The "external DLL discovery" option is mainly for modengine extensions but will happily load other mod DLLs. When a DLL is loaded that isn't an extension you'll see a message in modengine.log like this:

Unable to load extension my_dll.dll at base address 0xF.............

That means the DLL was loaded, but it wasn't a "valid" extension. I'll update this to log more about what's actually happening.

Yeah man I need to get the mod launcher to kick off ER but with it's filename being "eurotrucker2.exe" +1 to this feature request, sounds like a good addition and could be useful to multiple users. Or just 1
