The main thing here is that there are new controller settings that allow for more freedom. Unfortunately though, Nintendo Switch is missing out on much of what other platforms are getting. Konami implemented various settings for other platforms including resolution and upscaling. However, these options are not available on Nintendo Switch.
Below are the patch notes for the Nintendo Switch version:
Metal Gear Solid: Master Collection Vol. 1 update version 2.0.0 patch notes
- Added Controller Settings
- The option "Controller Settings" has been added under Additional Settings.
- You can assign controls for your controller under "Controller Settings"
- Fixed some other minor issues
