Retrobat: the Ultimate Guide to Arcade on Windows 2026

Retrobat is the ultimate emulation frontend for Windows. It is a free and open-source solution that automates the setup of EmulationStation (the graphical interface) together with RetroArch and many standalone emulators. In other words: you copy your ROMs, run Retrobat, and within minutes you have a professional arcade system up and running.

Unlike Batocera (which requires a complete operating system), Retrobat runs inside Windows: you don’t need to partition drives or disable Secure Boot. Ideal for recycled PCs, gaming laptops or arcade machines with embedded Windows.

Current version: RetroBat 8.3.1 (16 October 2026). Since version 8, RetroBat is a fully 64-bit program, introduces the Game Control Center (a menu you open during a game with Select + East button on your controller) and the installer only includes RetroArch: the other emulators are downloaded automatically the first time you launch a game that needs them, except for Switch, TeknoParrot and paid emulators.

Step-by-Step Installation

Download from the same page:

Visual C++ Redistributables All-in-One → run install_all.bat

Retrobat will scan your ROMs and download metadata automatically
The first time you open a game from a new system, Retrobat will download its emulator: make sure you are connected to the internet
Ready to play!

Adding Games (ROMs) and BIOS

ROMs

Prepare your ROMs: they must be copies of games you own the originals of
Copy each ROM into the right subfolder inside roms
Run Retrobat → it detects them automatically
Go to Main menu → Scraper to download covers and metadata

BIOS

Some systems need BIOS files:

PS1: scph5500.bin, scph5501.bin, scph5502.bin
PS2: ps2-0230a-20080220.bin (or equivalents)
Sega CD / Mega CD: bios_CD_U.bin, bios_CD_E.bin, bios_CD_J.bin
Neo Geo: neogeo.zip
Dreamcast: dc_boot.bin, dc_flash.bin

Put the BIOS files in the bios folder. Retrobat has a BIOS Checker in the menu to see which files are missing.

Controller Setup

Automatic mapping (most XInput controllers)

Connect your controller via USB or Bluetooth
Retrobat automatically detects Xbox, DualShock 4, DualSense, Switch Pro, 8BitDo controllers…

Manual mapping

In EmulationStation, press Start → Controller Settings → Controller Mapping
Hold down a button on the controller until it is recognised (3 seconds)
Follow the on-screen prompts for each button
For the HotKey, we recommend assigning Select or a dedicated button

Keyboard shortcuts (if you have no controller)

Action	Key
Main menu	Enter
Navigate	Arrow keys ↑↓←→
Select	X
Back	Z
Quit game	Hotkey + Start

Retrobat on an arcade machine

Retrobat is a good choice if your arcade machine has a PC or Mini PC with Windows. What changes compared with playing on a gamepad:

Joysticks and buttons: they connect to the PC via USB with a Zero Delay interface, one per player. Windows recognises it as just another controller, so you set it up with the manual mapping described in this article: hold a button until Retrobat detects it and follow the prompts.
Hotkey: on an arcade control panel it is best to use the Coin or Select button as the Hotkey, so you can quit games and open the Game Control Center without a keyboard.
Real arcade: besides MAME, Retrobat integrates TeknoParrot for modern arcade games and supports light guns such as Sinden, Aimtrak or Gun4IR.

If you are building your machine from scratch, our packs with USB interfaces include the cabinet, the joysticks, the buttons and one Zero Delay interface per player: you only need to add the PC with Retrobat and the monitor. If you are still deciding between PC, Raspberry Pi or Pandora, we help you choose in What system for arcade machine?, and we compare Retrobat with Batocera, Recalbox and co. in the best arcade emulation systems.

Advanced Customisation

Themes

Main menu → UI Settings → Theme
Download new themes directly from Retrobat (Theme Downloader option)
Popular themes: Carbon (default), Epic Noir, Art Book

Shaders (visual effects)

Access them during a game: Hotkey + L1/R1 (depending on your settings)
Recommended options:
- crt-royale: simulates a professional CRT monitor
- zfast-crt: lightweight, ideal for modest PCs
- scanlines: classic scanlines

Bezels (screen frames)

Retrobat automatically adds decorative frames when the game doesn’t fill the whole screen (e.g. 4:3 games on a 16:9 monitor). You can:

Download bezel sets from the menu
Turn them on/off per system in Game Settings

Netplay (online multiplayer)

Make sure the game/core supports netplay
Game menu → Netplay Settings
Set up a relay server or direct connection
Share your room or join an existing one

Common Problems and Solutions

Retrobat won’t start / black screen

Likely cause	Solution
VC++ or DirectX missing	Install the dependencies from the Retrobat website
Incompatible GPU	Check that your graphics card supports OpenGL 4.4+/Vulkan
Wrong resolution	Edit `retrobat.ini` and adjust `WindowWidth` / `WindowHeight`

Games don’t appear in the list

Likely cause	Solution
Wrong extension	Check that the ROM has the right extension (`.zip`, `.iso`, `.chd`)
Wrong folder	Put the ROM in the right subfolder inside `roms`
Not scanned	Go to Game Settings → Update Gamelist

The controller doesn’t respond / wrong mapping

Likely cause	Solution
Non-XInput controller	Use an Xbox-compatible controller or software such as x360ce
Corrupt settings	Open BatGUI → SDL Library → Reset Gamepad Config
Conflict with Steam	Close Steam (it sometimes intercepts the controller)

PS2/GameCube/Wii games run slowly

Likely cause	Solution
Hardware not powerful enough	Lower the internal resolution in Advanced Game Options
Shader too heavy	Turn shaders off or use a light one (zfast-crt)
Wrong graphics backend	Switch between OpenGL/Vulkan/Direct3D in the emulator options

No sound

Check that Windows’ default audio device is the right one
In RetroArch (during a game), press Hotkey + B → Audio → check the volume

“BIOS missing” error

Go to System Settings → Missing BIOS Check
Identify which files are missing for that system
Put them in the bios folder
