Important

❤️ Many thanks to all emulator developers. Without you and your awesome work this wouldn't be possible.

Pre Configured

All Systems are pre configured. This means the following:

Gamepad Mapping

All connected gamepads will be configured for the specific Emulator and should just work without further tinkering.

Keyboard Mapping

If there are no gamepads connected, the keyboard will be configured instead.

Keyboard Mapping

Button	Key
dpadUp	T
dpadDown	G
dpadLeft	F
dpadRight	H
a	J
b	K
x	U
y	I
back	BACKSPACE
start	RETURN
leftStick	X
rightStick	RSHIFT

Hotkeys

The following Hotkeys are set:

• Open Emulator Menu (if supported from emulator): F2
• Save State: F1
• Load State: F3
• Fullscreen: F11

Close a Game

You can close a game via

• Xbox: back + a
• PlayStation: select + x
• Nintendo: select + a

Steam Deck sorted last

If you have gamepads connected with your Steam Deck the Steam Deck Controls will be configured as the last gamepad. This is done to use the Steam Deck on a TV. If you have other PC Handhelds where this feature would come in handy, please let me know.

Bundled

All emulators are provided with emuze in a specific version.

Config files of bundled emulators are stored in ~/.local/share/emuze/emulators/ on linux and AppData\Local\emuze\Data\emulators\ on windows.

BIOS needed

Some emulators need a BIOS or firmware to run. If so you have to set the folder to your BIOS files in the settings. emuze will detect the appropriate file and configures the emulator accordingly.

For some emulators a open source BIOS implementation is bundled with emuze:

System	Open Source BIOS implementation
SNK Neo Geo	neogeo-bios
Nintendo Game Boy Advance	gba-bios
Sony PlayStation	PCSX Redux Openbios

❤️ Many thanks to the creators. Your work is a big step forward simplifing emulation.

Note

Capitalization, special characters and white spaces do not matter in a System Name. E.g. TurboGrafx-16 will be detected as well as turbo grafx 16.

Note

emuze can create the System Folders in the selected Roms Folder. Use the "Create System Folders" Button under Settings General.

🚀 Getting started

🪟 Windows

1. Download the latest Version of emuze and install it

2. Choose the folder where your Roms are located

🐧 Linux

1. Download the latest Version of emuze

2. Mark the AppImage as executable and start emuze

3. Choose the folder where your Roms are located

🎮️ Steam Deck in Game mode

1. Switch to Desktop

2. Download the latest Version of emuze

3. Mark the AppImage as executable

4. Add it via Add a Non-Steam Game to Steam and rename it to emuze

5. Switch to Game Mode and start emuze

6. Choose the folder where your Roms are located

Steam Input Profile

There is a Steam Input Profile with the name emuze, which has some Hotkeys pre configured on the back pedals of the Steam Deck.

• L4: Save State
• L5: Load State
• R4: Open Emulator Menu (if supported from emulator) or Fullscreen
• R5: Left Mouse Click
• Left Trackpad: Scroll Wheel
• Right Trackpad: Mouse

SteamGridDB

There are several assets for emuze on SteamGridDB which you can use via the SteamGridDB Plugin in Decky Loader.

On an external Monitor / TV

If you use your Steam Deck on an external Monitor or TV I recommend switching to the native resolution via Properties -> Shortcut -> Game Resolution to Native.

Roms Folder

The Roms need to be grouped by their System. E.g. Final Fantasy VII.chd needs to be stored in a folder PlayStation.

roms
|-> PlayStation
|---> Tekken 2.chd
|---> Crash Bandicoot.chd
|---> Final Fantasy VII.chd
|---> ...
|-> Super Nintendo
|---> Super Metroid.sfc
|---> Terranigma.sfc
|---> ...

Note

emuze can create the System Folders in the selected Roms Folder. Use the "Create System Folders" Button under Settings General.

🔫 Lightgun Support

emuze provides basic Lightgun support. Only the Retro Shooter Reaper was tested but others should work too.

You can navigate emuze with the pointer and confirm with the Trigger or use the stick and the Buttons on the side:

• Button 1 (Keyboard 1): confirm
• Button 2 (Keyboard 5): go back

The connected Lightgun will be configured automatically for the following systems:

PlayStation

emuze configures the connected Lightgun as a GunCon.

PlayStation 3

emuze configures the connected Lightgun as a PS Move Controller.

PS Move Controller Mapping

PS Move Button	Lightgun Button
T	Trigger (Mouse Button 1)
Start	Reload Button (Mouse Button 3)
Select	Button 2 (Keyboard 5)
Move	Alternate Reload Button (Mouse Button 2)
Combo	Button 1 (Keyboard 1)
Triangle	Button 1 + Button 2
Circle	Button 1 + Alternate Reload Button
Cross	Button 1 + Trigger
Square	Button 1 + Reload Button

Important

The Lightgun only works in window mode. Therefore emuze deactivates fullscreen mode for PlayStation 3 games if the Lightgun is connected.

Steam Deck

The Lightgun can be used with a Steam Deck too, but you have to switch to Desktop Mode and start emuze there.

📃 External Data

emuze relies on the following external data:

Data	Usecase
IGDB	is used to provide Metadata for your games
MAME xml list (mame -listxml)	is used to map MAME IDs to game names
ScummVM games list (scummvm --list-games)	is used to map ScummVM IDs to game names
nus-info	is used to map WiiU Title IDs to game names
SerialStation	is used to map PlayStation 3 Title IDs to game names
SDL_GameControllerDB	is used to add missing sdl controller mappings
Annie Use Your Telescope Font	is used for the emuze logo
Quicksand Font	is used for all the text
React Icons	is used for several System Icons
Xbox Series Button Icons and Controls	is used for the Button Icons
