A content downloader that can download files directly on Nintendo DS(i) consoles.
Concept inspired by pkgi-psp and Universal-Updater.
Features
- Multi-platform content download.
- Database loading via URL or file.
- Support for multiple databases.
- ZIP file extraction.
- Automatic updates check.
- Customizable color scheme.
- Localization support.
Installation
Place kekatsu.nds anywhere on the SD card.
Kekatsu expects a databases.txt to load as the list of available database:
root |-Kekatsu\ | |-databases.txt
Each line of the databases.txt file has to contain a name and a value separated by a '=' or ' ' (tab) character.
The name should be the display name of the database. The value must be either:
- an HTTP(S) URL which returns a database in text response
- a path to a database file on the SD card itself
Example databases.txt:
test-db https://example.com/database.txt test-db2 /databases/db2.txt
If you want to use the UDB-Kekatsu-DS database, copy the following text into databases.txt:
UDB-Kekatsu-DS=https://gist.githubusercontent.com/cavv-dev/3c0cbc1b63ac8ca0c1d9f549403afbf1/raw/
