Add sources for Windows

[ingobeans]

Is your feature request related to a problem? Please describe.
Windows seems to lack almost all sources except from Steam, Heroic and Itch.
Describe the solution you'd like
I would really like the missing sources added, at least retroarch.

Describe alternatives you've considered
Another game launcher?

The difficulty with this is how Windows handles executables, given these sources can't open games via URIs. Notably, they don't really have a viable alternative to $PATH, meaning the way executables are searched for is different. The whole system will have to be reworked for this to be possible, so it's not a small task.

So it's just an issue of accessing/finding the executable? If I understand correctly, couldn't the user be allowed to enter a path to the exe? (Alternatively forcing the user to add game launchers to path)
Thanks for the response!

That would be bad UX. There is a way for the software to get the executable path automatically, so it should. The user shouldn't need to hunt that down. I'd rather have a proper implementation in than a half-assed feature that requires the user to browse through system files.

Okay. But if the alternative is not having the sources (as of now), I think it's something worth considering. I also believe anyone going through the hassle of using RetroArch is fine with entering the path to the exe

I'm not adding incomplete features to the app, sorry. If it can be done good, I will not do it bad before fixing it, instead I'll just add if it it's good.
