DevMenu – 3DS Homebrew: The CIA Manager That Lives on Your HOME Screen

DevMenu is a developer menu and CIA manager built for homebrew-enabled Nintendo 3DS consoles. In plain terms, it is the tool that lets you install CIA-packaged content — games, eShop titles, DLC, themes and emulators — directly from your SD card. The package you download here contains both a .3ds ROM and a .cia file, and the workflow is designed so that you only need the ROM once. Load BigBlueBox as a 3DS ROM, install the .cia version, and DevMenu (Title Manager) becomes a permanent icon on your HOME screen. From that point on, every .cia file you drop onto the root of your SD card can be installed without touching a Gateway ROM list again.

That two-step structure is what makes this release practical. Instead of booting an emuNAND and hunting for a ROM every time you want to add something, you install the manager once and keep it. The download is small — just 2MB — and it is distributed as free software by developer Berry.

What DevMenu Actually Does

DevMenu is best understood as a title manager. Once it is installed on your HOME screen, you use it to read .cia files placed at the root of your 3DS SD card and install them as system-recognized titles. The source material for this release lists the supported content types clearly: games, eShop games, DLCs and themes. Because emulators are also distributed as .cia packages in the 3DS homebrew scene, you can install those the same way.

The install flow described by the developer is straightforward and worth repeating exactly, because the order matters:

1. Extract the .3ds file and copy it to your Gateway's MicroSD card like a normal ROM.
2. Copy the .cia file to the root of your 3DS SD card.
3. Boot the emuNAND as usual and load DevMenu (Title Manager) from the ROM list.
4. Choose the second tab, select DevMenu.cia, and press A to install.
5. After installation, delete the .3ds and .cia files if you want — DevMenu stays on your HOME screen.

From then on, whenever you want to install something new, you place the .cia file at the root of your SD card and install it through DevMenu. That is the entire loop.

Key Features

• CIA installation from SD card — install packaged apps, games, eShop titles, DLCs and themes directly from .cia files placed at the root of your SD card.
• Persistent HOME screen entry — the .cia version installs as a title, so DevMenu (Title Manager) remains accessible without reloading a ROM each session.
• Dual-format package — the download includes both a .3ds ROM for the initial Gateway boot and a .cia file for permanent installation.
• Tab-based title manager interface — the second tab is where you select and install the .cia file, with the A button confirming the install.
• Emulator-friendly — CIA-packaged emulators install through the same flow as games and apps.
• Small footprint — the whole package is 2MB, so it takes almost no space on your MicroSD or SD card.

Who This Is For

DevMenu targets a specific audience: people who already run a homebrew-enabled 3DS with a Gateway card and an emuNAND setup. If you are comfortable copying files to a MicroSD, booting emuNAND and picking a title from a ROM list, this tool fits your existing workflow. If you have never set up homebrew on a 3DS, DevMenu is not a starting point — it assumes the surrounding environment already exists.

The Gateway requirement is explicit in the source: keep your Gateway updated to version 2.6 or higher. That is the one hard dependency stated by the developer, and it is worth checking before you begin.

Pros & Cons

Pros

• One-time installation — after the .cia is installed, the .3ds and .cia files can be deleted, freeing your card.
• Handles multiple content types from a single interface: games, eShop titles, DLC, themes and emulators.
• Very small download at 2MB, with no impact on SD card capacity.
• The install path is documented step by step, including the exact tab and button used.
• Described by its publisher as the most up-to-date version of the tool.

Cons

• Requires a Gateway card at version 2.6 or higher — it will not work on an unmodified console or a non-Gateway setup.
• Depends on an emuNAND workflow, which adds setup overhead for newcomers.
• No version number or changelog is published in the source listing, so you cannot verify build freshness from the page alone.
• No official support channel or update history is documented in the provided material.
• The interface is a developer menu, not a polished consumer storefront — expect a functional, utilitarian layout.

Version Freshness and Publisher Details

The source listing does not publish a version number or a changelog for this release, so this article does not invent one. What the listing does state is that this is the most up-to-date version of DevMenu available at the time of publication, and that it requires Gateway firmware 2.6 or newer. The publisher is credited as Berry, and the software is offered free of charge.

Because no version string is provided, treat the build as current-but-unverified. Before installing, confirm that your Gateway is on 2.6 or higher and that your emuNAND boots normally. If either check fails, resolve that first — the DevMenu install step assumes both are already working.

Practical Installation Guidance

The critical detail most people miss is file placement. The .3ds file goes on the Gateway's MicroSD card, exactly like any other ROM. The .cia file goes at the root of the 3DS SD card — not in a subfolder. DevMenu reads from the root, and a .cia buried in a directory will not appear where you expect it.

When you load DevMenu from the ROM list, switch to the second tab before selecting the file. Press A to install, and wait for the process to finish before powering down. Once it completes, the title manager is a permanent HOME screen icon, and the two source files are no longer needed.

If you also follow the wider homebrew scene, you may want to look at other community-made releases such as Grand Theft Auto V Switch NSP [Homebrew Port], which shows how far fan-driven ports have come on Nintendo hardware. Fans of oddball indie experiments might also enjoy Buddy Simulator 1984 Switch, and narrative-driven players can explore We Are Eva Switch for free. These are separate downloads from DevMenu, but they sit in the same homebrew-friendly corner of the Nintendo ecosystem.

Download Links

The publisher provides two separate files. Grab the one you need — or both, if you are doing the full ROM-then-CIA install:

Dev Menu.3DS — download the ROM file
Dev Menu.CIA — download the CIA file

For extracting RAR files, use WinRAR or 7Zip.

Final Thoughts on DevMenu

DevMenu solves one problem well: it gives your 3DS a permanent, always-available title manager so you stop repeating the ROM-boot ritual every time you want to install a .cia. The 2MB download, the dual .3ds/.cia packaging and the clear two-tab install flow make it a sensible utility for anyone already running Gateway 2.6+ with emuNAND. The tradeoff is that it is tightly coupled to that environment — there is no version number to check and no support documentation beyond the steps above. If your setup matches the requirements, DevMenu is a small, free, and direct way to manage CIA content from your HOME screen.
