Unification menu between Windows and Linux versions (need help)

[TotalCaesar659]

I've tried to fix #10484. Some menu points are not implemented (cause I don't know how), some may be bugged, so I push it for checking.

Sorry for the lack of reply here. I think it'd be better to break this up and start with just the items you know what do and are implemented. That'll make it easier to review and easier to explain the ones that are still missing.

Do you want me to close this PR and start it partially over again?

I'm generally a fan of updating existing pull requests, but either way is fine. I think we should split up the commits to make it easier.

Some of these options I think are actually Windows specific or may require non-trivial work to implement for Qt. But there are other menu items we could update and get in real soon. I think splitting it up is the first step.

Some examples:

• bVSync - this is actually forced on for Linux / Qt / etc. right now. It may be possible to disable but it's going to be more work than just the menus.
• Open directory is intended to open a folder/directory which is an extracted ISO. It's usually used for rom hacking.

In general it looks like most of the menu items you added are working and look good, so it's hard for me to even tell which ones you're most concerned about.

OK, I think I'll better to make fresh PR with split commits and only those options that I'm sure, thanks.
