NEO.emu review
A paid, open-source emulator with broad Neo Geo support and flexible controls.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NEO.emu is an open-source emulator for Neo Geo MVS and AES software, aimed at players who want configurable controls and support across Android, iOS and Linux. It is based on a modified version of GnGeo and supports MAME 0.144 or newer ROM sets. The app covers both arcade-style MVS software and home-console AES software, while configurable on-screen controls accommodate touchscreen play. Bluetooth and USB HID gamepads and keyboards provide alternatives for users who prefer physical input.
Its strongest feature set is focused on compatibility and system configuration. Universe BIOS support includes region and mode editing, giving users control over how supported software is configured. Game caching uses .gno files, and autosave plus manual save states support interrupted sessions. These features make NEO.emu more flexible than a narrowly focused emulator, particularly for users moving between different Neo Geo modes or control setups. ROM files are not included, so users need to provide compatible files separately.
NEO.emu is distributed as a paid app rather than a free-plan product. That makes it a clearer fit for users who specifically want Neo Geo MVS/AES emulation, save states, BIOS options and external controller support in one package. It is less suited to anyone seeking a free starting point or an emulator with included game content. Players who already have compatible ROM sets and want cross-device options should find the feature scope relevant; those who want an all-in-one library or no-cost access should consider a different option.
