NEO.emu for Android

Overview

NEO.emu is a robust, open-source Neo Geo emulator for Android devices. Derived from the Gngeo project, it focuses on delivering smooth, responsive gameplay through a simple user interface and minimal audio/video lag. The app does not bundle game ROMs — users must obtain those separately.

Compatibility and performance

Designed to run well on a broad range of hardware, NEO.emu works on both modern phones and older handhelds. It emphasizes low latency to make action and fighting games feel immediate.

• Nvidia Shield and similar high-end devices
• Google Pixel series and other current phones
• Legacy hardware such as the Xperia Play

Controls and input options

The emulator offers flexible input methods so you can play the way you prefer, whether that’s touch, a gamepad, or a physical keyboard.

• Support for keyboards and console-style controllers recognized by Android (for example, Xbox and PS4 controllers)
• Bluetooth and USB gamepad compatibility
• Customizable on-screen controls that can be adjusted to taste

System files and ROM support

NEO.emu requires the standard Neo Geo BIOS package to function correctly and can load multiple types of ROM collections.

• Uses the neogeo.zip BIOS file (must be supplied by the user)
• Compatible with MAME-style ROM sets and newer collection formats
• No ROMs are included with the app — users must provide their own copies

Storage access and file management

Opening games is straightforward thanks to Android’s file-handling features.

• Works with Android’s Storage Access Framework for access to internal memory
• Can open files from external media such as SD cards and USB drives

Notes

Because it’s open source and based on Gngeo, NEO.emu is a good choice for users who want a lightweight, configurable Neo Geo experience on Android devices.
