# custom-install
|
|
Experimental script to automate the process of a manual title install for Nintendo 3DS. Originally created late June 2019.
|
|
|
|
## Summary
|
|
|
|
### Windows standalone
|
|
|
|
1. [Dump boot9.bin and movable.sed](https://ihaveamac.github.io/dump.html) from a 3DS system.
|
|
2. Download the [latest releases](https://github.com/ihaveamac/custom-install/releases).
|
|
3. Extract and run ci-gui. Read `windows-quickstart.txt`.
|
|
|
|
### With installed Python
|
|
Note for Windows users: Enabling "Add Python 3.X to PATH" is **NOT** required! Python is installed with the `py` launcher by default.
|
|
|
|
1. [Dump boot9.bin and movable.sed](https://ihaveamac.github.io/dump.html) from a 3DS system.
|
|
2. Download the repo ([zip link](https://github.com/ihaveamac/custom-install/archive/module-newer-gui.zip) or `git clone`)
|
|
3. Install the packages:
|
|
* Windows: Double-click `windows-install-dependencies.py`
|
|
* Alternate manual method: `py -3 -m pip install --user -r requirements-win32.txt`
|
|
* macOS/Linux: `python3 -m pip install --user -r requirements.txt`
|
|
4. Run `custominstall.py` with boot9.bin, movable.sed, path to the SD root, and CIA files to install (see Usage section).
|
|
5. Download and use [custom-install-finalize](https://github.com/ihaveamac/custom-install/releases) on the 3DS system to finish the install.
|
|
|
|
## Setup
|
|
Linux users must build [wwylele/save3ds](https://github.com/wwylele/save3ds) and place `save3ds_fuse` in `bin/linux`. Install [rust using rustup](https://www.rust-lang.org/tools/install), then compile with: `cargo build`. The compiled binary is located in `target/debug/save3ds_fuse`, copy it to `bin/linux`.
|
|
|
|
movable.sed is required and can be provided with `-m` or `--movable`.
|
|
|
|
boot9 is needed:
|
|
* `-b` or `--boot9` argument (if set)
|
|
* `BOOT9_PATH` environment variable (if set)
|
|
* `%APPDATA%\3ds\boot9.bin` (Windows-specific)
|
|
* `~/Library/Application Support/3ds/boot9.bin` (macOS-specific)
|
|
* `~/.3ds/boot9.bin`
|
|
* `~/3ds/boot9.bin`
|
|
|
|
A [SeedDB](https://github.com/ihaveamac/3DS-rom-tools/wiki/SeedDB-list) is needed for newer games (2015+) that use seeds.
|
|
SeedDB is checked in order of:
|
|
* `-s` or `--seeddb` argument (if set)
|
|
* `SEEDDB_PATH` environment variable (if set)
|
|
* `%APPDATA%\3ds\seeddb.bin` (Windows-specific)
|
|
* `~/Library/Application Support/3ds/seeddb.bin` (macOS-specific)
|
|
* `~/.3ds/seeddb.bin`
|
|
* `~/3ds/seeddb.bin`
|
|
|
|
## custom-install-finalize
|
|
custom-install-finalize installs a ticket, plus a seed if required. This is required for the title to appear and function.
|
|
|
|
This can be built as most 3DS homebrew projects [with devkitARM](https://www.3dbrew.org/wiki/Setting_up_Development_Environment).
|
|
|
|
## Usage
|
|
Use `-h` to view arguments.
|
|
|
|
Examples:
|
|
```
|
|
py -3 custominstall.py -b boot9.bin -m movable.sed --sd E:\ file.cia file2.cia
|
|
python3 custominstall.py -b boot9.bin -m movable.sed --sd /Volumes/GM9SD file.cia file2.cia
|
|
python3 custominstall.py -b boot9.bin -m movable.sed --sd /media/GM9SD file.cia file2.cia
|
|
```
|
|
|
|
## GUI
|
|
A GUI is provided to make the process easier.
|
|
|
|
### GUI Setup
|
|
Linux users may need to install a Tk package:
|
|
- Ubuntu/Debian: `sudo apt install python3-tk`
|
|
- Manjaro/Arch: `sudo pacman -S tk`
|
|
|
|
Install the requirements listed in "Summary", then run `ci-gui.py`.
|
|
|
|
## Development
|
|
|
|
### Building Windows standalone
|
|
|
|
Using a 32-bit version of Python is recommended to build a version to be distributed.
|
|
|
|
A [virtual environment](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment) is recommended to isolate the packages from system directories. The build script `make-standalone.bat` assumes that the dependencies are in PATH.
|
|
|
|
Install the dependencies, plus cx-Freeze. In a virtual environment, the specific Python version doesn't need to be requested.
|
|
```batch
|
|
pip install cx-freeze -r requirements-win32.txt
|
|
```
|
|
|
|
Copy `custom-install-finalize.3dsx` to the project root, this will be copied to the build directory and included in the final archive.
|
|
|
|
Run `make-standalone.bat`. This will run cxfreeze and make a standalone version at `dist\custom-install-standalone.zip`
|
|

Thanks to @nek0bit for redesigning `custominstall.py` to work as a module, and for implementing an earlier GUI.
|
|
|
|
Thanks to @LyfeOnEdge from the [brewtools Discord](https://brewtools.dev) for designing the second version of the GUI. Special thanks to CrafterPika and archbox for testing.
