Beyond the 20 games pre-installed on the Neo Geo Arcade Stick Pro, there are additional titles you can access. Some are added through official SNK USB upgrade files; others have been discovered or unlocked by the community. This page summarizes what is widely known about hidden and extra games so you can decide whether to stick with the base set or expand your library.
Official USB Upgrades
SNK has released official upgrade files that you load onto a USB drive and plug into the Arcade Stick Pro. These updates add more games to the system. For example, Metal Slug 1 and Metal Slug 2 have been added via such USB upgrades. The process is supported by SNK and does not require modding. Check SNK's official site or support channels for the latest upgrade files and instructions. Applying an upgrade typically involves downloading the correct file, placing it on a FAT32 USB drive, and following SNK's steps (e.g., inserting the USB and booting or using a specific menu option).
Community-Unlocked / Discovered Titles
Fans have reported or documented additional Neo Geo titles that can appear or be unlocked on the Arcade Stick Pro. The exact method and full list can vary; some titles were added by official updates, others through unofficial means. A commonly cited set of extra or hidden games includes:
- Fatal Fury (first game)
- Fatal Fury 2
- Real Bout Fatal Fury Special
- Savage Reign
- Art of Fighting 3
- The Last Blade (first game)
- Samurai Shodown (first game)
- Metal Slug series (1–5, X, etc.)
- Ninja Combat
- The Super Spy
- Shock Troopers (including 2nd Squad)
- League Bowling
- Soccer Brawl
- Super Sidekicks
Not all of these are available on every unit or through official upgrades alone. Some are only known from community discoveries or mods. If you want to explore beyond the official 20 plus SNK USB updates, the hack page covers community firmware and loading ROMs from USB, which can significantly expand the library but is unofficial and may void your warranty.
Why Hidden Games Matter
The base 20 games already cover many of SNK's best-known fighters. Adding Metal Slug via official upgrade is a big plus for run-and-gun fans. Other titles (e.g., earlier Fatal Fury or Samurai Shodown entries, Shock Troopers, League Bowling) give you more variety without buying another device. If you prefer to stay fully official, stick to SNK's USB upgrades. If you're comfortable with modding, community hacks can unlock or load many more Neo Geo titles; just be aware of the risks.
How to Get Official Upgrades
Visit SNK's official Neo Geo Arcade Stick Pro support or product page. Download the upgrade file(s) they provide and follow their instructions exactly. Usually you will need a USB drive formatted as FAT32, the correct file name and folder structure, and a specific procedure (e.g., power off, insert USB, power on, or use an in-system update option). Do not use upgrade files from untrusted sources, as they could damage the device or violate terms of use.
Summary
The Arcade Stick Pro can play more than the default 20 games. Official SNK USB upgrades add titles like Metal Slug 1 and 2. The community has also identified or unlocked other Neo Geo games (e.g., more Fatal Fury, Samurai Shodown, Metal Slug, Shock Troopers). For official support, use only SNK upgrades. For maximum expansion, see the hack page and understand the risks of modding.
