Slot-1 per-game settings menu

[Barawer]

Is your feature request related to a problem? Please describe.

No

Describe the solution you'd like

Ability to select slot 1 settings, just as the per game settings allows. I mainly wanted to make sure I was running the game in TWL speed.

Describe alternatives you've considered

Either in the settings page or like the per settings menu.

Additional context

In general games running from slot 1 are a bit cumbersome to run. I can always dump them but that just adds additional steps in playing my carts..
