@Shadow666 Everything runs slowly and the sound is very choppy with recalbox? Surely it can't be throttling the cpu
What games are you running? Everything runs great bar N64 atm with the 9.2 release on the site. If you have a patreon account you can get the latest beta where n64 runs better. They even have killer instint arcade version at full speed with Mame 2003.
I tested fbneo and they seem to be running a very old core, they are missing a lot of features which are on the official build.
Recalbox support seems to be focused on French which is a pain as it is not a language I am good at.
How can I skip the Button A / East (and other options I don't have)?
You can't. Some buttons are required, since they are used to launch games and/or navigate the EmulationStation front-end. A and B are such buttons and they cannot be skipped.
You can however map your keyboard to navigate EmulationStation as you'd like. Of course, you'll need to configure your gamepad manually in the emulators started, since it's not configured by EmulationStation.
@arcadelover15 There wasn't a whole lot to it. The box itself is designed to be used as a controller if you want, so it was just a matter of hooking up BOTH usb cables to the Pi. (Each cable is one side of the control panel.) I think the setup tweak I used initially might be no longer needed in current versions of RetroPi.
@tmxretro the "h" key is the default retroarch "reset content" hotkey and, without a controller connected, there is no default "enable hotkey" hotkey configured, so all the other ones (like "reset content") will work on their own, with just a single keypress.
You can toggle game focus with the "game focus (toggle)" hotkey (default: scroll_lock, configurable from settings > input > hotkeys > game focus (toggle)). While game focus is enabled, other hotkeys (including "exit emulator") will not function, passing full keyboard control to the loaded core; press scroll_lock again to disable game focus and return hotkey functionality.
@mitu thanks for the response, unfortunately lr-mame2000 doesn't run any of my roms (it's a pretty old set, not sure if that's a problem or not). I've spent far too much time on this so I think I'll just get some USB-powered speakers and use the adapter device. Cheers!
