PiPifier VS OpenEmu

Works like a charm, also open source on GitHub. Thanks!

Pipifier (free) - Safari extension that enables you use the native macOS picture in picture function on pretty much every site (like Netflix) Available for the Mac App Store

Tangentially related: if anybody is looking for a good way to organize a library of retro emulators and games on their MacOS laptops/desktop computers then I recommend OpenEmu. It is designed from the ground up to look and feel like a Mac app.

Just follow the link i posted. Btw you can build OpenEmu in a couple of minutes yourself. Some controllers (PS5 for example) are natively supported, more shader options, and other small stuff..

Download Openemu 2.0.9.1 https://github.com/OpenEmu/OpenEmu/releases/tag/v2.0.9.1

As far as I know, devs have no plans to allow multiple bindings to the same inputs. It is apparently too complicated for them to implement. See: https://github.com/OpenEmu/OpenEmu/issues/4600

The Pocket is a great device, highly recommended, get the Dock if you want to buy one. While waiting, I recommend using https://openemu.org/ on your Mac to run "roms", which are files that represent old games. To get the ROMs, google for "tubrografx roms archive.org". Then for a controller on a Mac, you can use a PS4/PS5 or Xbox (One/Series), if you have one lying around. That said, I recommend buying an SN30 Pro.

Download and Install OpenEmu

Huh? Try http://openemu.org/ and download the experimental version (with arcade support)

Yeah should be pretty easy if you have the ISO or a disc copy, OpenEmu should do it without issue - https://openemu.org

Otherwise you can try OpenEmu: it's a very Mac friendly emulator of a lot of old systems that works by dragging/dropping the roms in it. The "Experimental" (direct link) build includes support of Mame, which means support of Neo Geo roms.
