Got myself [a tiny 8BitDo controller](https://a.co/d/2eNjym2) for use with the excellent [OpenEmu for macOS](https://openemu.org/) (can't believe it's free).

Many ROM sites appear to be broken but [Vimm's Lair](https://vimm.net/) appears to be active and offer quite a few. There's also the Reddit [/r/ROMS community](https://old.reddit.com/r/Roms/).

### Karabiner Remappings

Strictly optional.

The controller registers itself as a keyboard. I use the excellent Karabiner to remap the buttons so I don't have to remember which letter, for example, the "Up Arrow" on the controller is (it's `c`). Here's my config. It goes into a list under `profiles` -> `devices`.

I also used the `-` and `+` buttons at the top for `Select` and `Start` respectively.
