Luma3DS CFW
Custom firmware for the 2DS / 3DS family, including New models. It runs through a persistent exploit such as boot9strap; an archive alone does not install CFW on a stock console.

The six established resources and their pinned releases are preserved.
GodMode9
A full-access file browser for NAND backups, cartridge dumping and system maintenance. Follow its usage guide before making writes to system storage.
Universal-Updater
Find, install and update homebrew from Universal-DB and other Unistores directly on the console. Includes app search, screenshots and a download queue.
Checkpoint
Back up and restore supported game saves and extdata. Use the 3DS CIA on a prepared 2DS / 3DS, and keep an original backup before restoring or editing saves.
ftpd · Nintendo 3DS build
Access SD-card files from an FTP client on your local network. This CIA is the 2DS / 3DS build, separate from the Nintendo DS binary.
TWiLight Menu++ · 3DS
Launch DS-mode homebrew on a CFW-enabled 2DS / 3DS. Follow the 3DS-specific installation steps; its package differs from the DS flashcard and DSi builds.
Choose CIA, 3DSX or FIRM
- Prepare storageUse a genuine SD / microSD with FAT32 and an MBR partition table. The maintained guide recommends 2–128 GB; larger cards can introduce GBA graphics and custom-theme issues. Keep the entire existing Nintendo 3DS folder and your saves backed up.
- CIA apps: install to HOME MenuCopy a CIA to a convenient SD folder such as /cias/, then use FBI on your prepared CFW system to install it. Read the app requirements first. Universal-Updater is another route for supported apps.
- 3DSX apps: launch through Homebrew LauncherPut the executable in /3ds/ or its documented app subfolder. Copy bundled data directories separately to their specified SD paths. A lone 3DSX is not a replacement for required game data.
- FIRM files: boot payloadsFor tools that document it, put the FIRM under /luma/payloads/ and use the Luma chainloader at boot. Luma boot.firm itself belongs at the SD root; do not replace it with an app FIRM.
- DS mode: use the 3DS packageFollow TWiLight Menu++’s 3DS installation page. The DS flashcart and DSi packages use different instructions.
- Keep versions and dependencies togetherEach new download has an expandable file record with its original URL, exact version, byte count and SHA-256. Preserve supplied folders and follow the linked readme for BIOS, ROM or game-data requirements.
