dspatch.py

This is an application written in Python made to replicate the functionality of dspatch by Gericom. It accepts the same arguments as dspatch and outputs ROMs with the same functionality—namely modified DS Download Station ROMs that can send unsigned homebrew ROMs to other Nintendo DS, Nintendo DSi, and Nintendo 3DS systems over DS Download Play. Like the original dspatch, this supports including multiple ROMs in the output. In addition, this application also supports compressing ROMs to decrease transfer times using the -c option (requires Python-LZO to be installed).

How to use

Windows

Download and install Python from https://www.python.org/downloads/windows/. If you want to use compression, install Python-LZO as well.

If running Python 3.13 (from the command prompt):

>python.exe -m pip install bin\python-lzo\python_lzo-1.16-cp313-cp313-win_amd64.whl

If running Python 3.7 - 3.11:

>python.exe -m pip install python-lzo

Alternatively, build and install Python-LZO from source by following the instructions here.

Run dspatch.py to produce the ROM. You can use -i or -I multiple times to specify multiple ROM files or folders, respectively.

>python.exe dspatch.py -s download_station.nds -o [out_filename] -i [in_rom] -I [in_folder] [-c]

Linux

If it's not already installed, install Python using your distribution's package manager. Optionally, install Python-LZO as well to use compression.

Ubuntu/Debian:

# apt-get install python3
# apt-get install python3-lzo

Fedora (python-lzo requires building from source):

# dnf install python3
# dnf install python3-pip lzo python3-devel lzo-devel gcc
$ pip3 install python-lzo

Arch Linux (python-lzo requires building from source):

# pacman -S python
# pacman -S python-pip lzo gcc
$ pip3 install python-lzo

openSUSE:

# zypper install python3
# zypper install python3-python-lzo

Run dspatch.py to produce the ROM. You can use -i or -I multiple times to specify multiple ROM files or folders, respectively.

$ ./dspatch.py -s download_station.nds -o [out_filename] -i [in_rom] -I [in_folder] [-c]
