## Project history and usage

custom-install is a focused Nintendo 3DS utility for installing CIA files directly to an SD card. Its README describes it as an experimental script that automates a manual title-install process and says it was originally created in late June 2019.

### Project history

The public repository was created in September 2019, shortly after the README's stated June 2019 origin. The tool grew around a practical workflow: provide 3DS-specific files such as boot9.bin and movable.sed, run the installer against CIA files and an SD root, then finish the install on the console with custom-install-finalize.

### Adoption history

The project sits in the homebrew utility niche rather than the general gaming-tool mainstream. Its adoption is driven by users who already understand 3DS SD-card workflows, CIA files, and companion tools such as SeedDB, save3ds, and the finalize release.

### How it is used

Users run the command with explicit paths for boot9, movable.sed, an SD-card root, and one or more CIA files. The README documents platform-specific search paths for boot9.bin and seeddb.bin, but it does not define a persistent application configuration file.

### Why package nerds care

For package maintainers, custom-install is notable because it packages a console-homebrew workflow as a host-side CLI. It has unusual runtime expectations for a normal Unix package, including user-supplied console keys, SD-card access, and a companion finalizer used on the 3DS itself.

### Timeline

- 2019: Originally created in late June, according to the README.
- 2019: Public GitHub repository created in September.
- 2019: 2.0 tag appears in the upstream tag history.
- 2026: Repository still showed upstream activity.

### Related projects

- The README credits pyctr from ninfs, uses save3ds for Title Database interaction, and points users to custom-install-finalize releases.
