[Feature Request] Screen rotation and monitor index

[chrism69]

Overview

All the pinball games on the Switch have the option to rotate the screen to play in portrait mode, and other games like Arkanoid vs Space Invaders only display in portrait. If you can physically rotate your monitor then it works, but for users who already have a vertical monitor beside a normal horizontal monitor it's not so useful.

It would be nice if Ryubing had options to rotate the image in 90 degree increments, and to launch games on different monitors, so they could be added to custom configs per game.

Smaller details

Several other emulators have this feature including MAME and Retroarch.

Why would this feature be useful?

"Launching the game on a different monitor" is unlikely to be done, and if it's done by someone else it's unlikely to be added.
I can't see a way to add that which isn't disgusting, sprawling code. It's not like we have exclusive fullscreen capabilities (nor want them), so it'd involve manually moving the window, factoring in the new window's resolution, then restoring to a size equivalent to before. It sounds simple but it's not, when there's 3 different platforms we support; not to mention that an application moving itself is horrible UX.

If you're reading this and you think you can prove me wrong, please, do! This feature would be cool to have; I just don't think we could realistically make it in a way that I am happy with, and that works cross-platform.

Screen rotation won't be done by us (we have no games that do this), but I'd gladly accept that addition. Having to rotate the monitor, while true to the Switch experience, is an awful experience just to be able to play the games correctly.

Just to clarify about launching games on a different monitor, I can do it manually either by dragging the window or using Shift+Win+Arrows and then F11, it would just be nice to have that done automatically. For other emulators it's just settings like "screen \.\DISPLAY2" and "video_monitor_index = 2" in the config files.

Of course then I just have a small letterboxed window in a huge vertical screen, so that's when the rotation would be needed.

...I know what you mean by launching games on different monitors. I just explained why that won't be worked on
