About:
custom-install is a command-line utility that facilitates the direct installation of encrypted Nintendo 3DS CIA files to a 3DS SD card via a PC. It bypasses the need for wireless transfer tools like FBI by writing title data and cryptographic seeds directly to the SD filesystem. This streamlines the modding process, significantly reducing installation time for large titles or on systems with slow wireless connections.

Key Features:

Direct SD card writing for faster installations
Supports encrypted CIA files and seed injection
Python-based CLI for cross-platform usage
Bypasses wireless network limitations

Use Cases:

Installing large games or updates on modded 3DS systems without Wi-Fi bottlenecks
Restoring game backups from a PC to an SD card
Batch installing multiple titles efficiently

Alternatives:

FBI – FBI installs over WiFi or from SD but can be slow; custom-install is faster for direct SD transfers.
GodMode9 – GodMode9 is a general file manager; custom-install is specialized for CIA installation workflows.
