[Kman6664230]

I was wondering if u ever are gonna add controller support and the option to change the opacity on the screen buttons' cuz RN I can only use my arrow keys : 3

Controller support would be great, but unfortunately I don't have a controller.

Customizing the transparency of on-screen buttons is something I want to have myself, however in latest release I made the buttons 25% opaque when released

tried playing this on my Retroid Mini V2. Moving between menu items on the main menu worked, actually pressing anything didnt.
Using touch controls on a tiny android handheld is horrible
