BrewMate

Automated 3DS homebrew installation tool. Point it at your 3DS SD card, select your console type and firmware, and BrewMate handles the exploit chain, payload fetching, and on-console instructions.

• Automatic console/firmware detection from SD card ID0
• MSET9 exploit automation for 3DS/New3DS on firmware 11.0-11.4
• Payload fetching from GitHub releases with caching
• SD card structure validation and backup before modifications
• Post-install verification with NAND backup enforcement
• Cross-platform — Windows, macOS, Linux

BrewMate ships zero Nintendo code. It fetches open-source payloads (Luma3DS, boot9strap, SafeB9SInstaller, GodMode9, FBI) from their official repositories. Running homebrew on your own console is legal. This tool is for educational and personal use only.

python brewmate.py

# Or specify mode:
python brewmate.py setup      # Setup stock console (MSET9)
python brewmate.py finalize   # Finalize CFW installation

• Python 3.11+
• 3DS with stock firmware (11.0-11.4) or pre-hacked with CFW
• SD card (FAT32, recommended 8GB or larger)
• Internet connection (for payload downloads)

1. Insert 3DS SD card into computer
2. Run BrewMate → select console type + firmware
3. BrewMate prepares the SD card with MSET9 exploit
4. Reinsert SD card, follow on-console instructions
5. Continue to Finalization step

1. Reinsert SD card into computer
2. Run BrewMate → Finalize mode
3. Verifies CFW installation, installs essential homebrew
4. Prompts for NAND backup (critical!)
5. Done — enjoy CFW
