@Substring i have found something, but it is in German

@Substring Exit a Game is no problem but what is with Reload, Save, Lade Screenshot and so on. I what to have all Shortcut functions on a Keyboard.

Hotkey + Y → Save State
Hotkey + X → Load State
Hotkey + Up → Select Save Slot -1
Hotkey + Down → Select Save Slot +1

Hotkey + Start → End Game and Quit To Main Menu
Hotkey + A → Reset Game
Hotkey + B → Retroarch Menu
Hotkey + L1 → Screenshot

Hotkey + Right → Speedup game
Hotkey + Left → Rewind (if activated in options)

Hotkey + R2 → Next shader preset
Hotkey + L2 → Previous shader preset

I down't know how to script this.

hello everybody,
i have the following Problem.

I want to build a Hotkey Keyboard, to Exit the game with one button.
Also restart, save, load and anything else.

I have made a circuit with Diodes, to prevent that all Buttons are pressed. (So the theory).

The Problem from this circuit is, if you push to many Buttons on the same time, that the hotkey is also pressed.

Now my Question:

Can i use the GPIO Pints from the PI for this?
How do's the GPIO Controller works?
Can i use the CPIO Controller at the same time as the XinMo?

Thank you for your answer
BörgiM

Hi zusammen,

ich hab folgendes Problem.

Und zwar will ich eine Hotkey Tastatur bauen, damit man nur einen Button zum beenden von den Spielen drücken muss und keine Tastenkombination.

Dazu haben ich eine Schaltung mit Dioden gebaut damit nicht immer alle Tasten gedrückt werden (so die Theorie).

Problem bei dieser Lösung an dem XinMo Controller ist, dass wenn man wild am zocken ist dennoch die Hotkey Taste gedrückt wird.

Nun zu meinem Fragen.

Werden die GPIO Pins die für den Controller verwendet werden auch auf Masse kurzgeschlossen so wie bei den XinMo Controller?
Kann ich den XinMo und den GPIO Controller gleichzeitig verwenden ohne das Mapping immer umzustellen?
Kann ich zu not mit zwei XinMo arbeiten?
Oder kann ich die Hotkey Funktionen komplett auf einen GPIO Pin legen sodass meine Schaltung überflüssig wird?

Gruß und danke schon mal.
BörgiM

@Substring Hi,
I have uncommanded the config hdmi_safe=1 but the resolution is still the same.

Moin zusammen,

Das Recalbox Menü ist bei mir immer in der Auflösung 640x480.
Spiele werden aber immer in der richtigen Auflösung gestartet.

Der Monitor unterstützt eine max Auflösung von 1600x1200.
