Schedule is an organizer tool for Nintendo DS. Using it, you will be able to show, create, modify and delete single events or a sequence (daily or weekly) of events. The most important feature is that this tool can import and export your calendar in .ics format. This file format is compatible with Apple iCal, Firefox Calendar Project, Google Calendar and others.

It was submitted for the Neoflash Summer Coding Compo 2007 (winner).


Download the latest version and extract file.

Patch the nds with DLDI driver and upload the directory to your card.

The application requires a directory in the root called DSchedule with an additional file (optional) called dschedule.conf. In dschedule.conf you can set the starting calendar by writeing:

#Initial calendar file to load

The file name is without the .ics extension.

User guide

When the program starts, the upper screen contains the calendar of the current month. The lower screen contains a blank screen with some buttons, which from left to right:

Show help.
Load events stored in .ics file.
Save events into .ics file.
Enable/disable all events view (first click shows all events in calendar, second click return to the daily view).
Add new event.
Modify selected event.
Delete selected event.
Scroll up on the events list.
Scroll down on the events list.
Show the previous month.
Show the next month.
Swap upper and lower screen.

Load a calendar

To load a calendar from file, you have to move the .ics file into the memory card. When you will try to load it, the program will ask you the path. For an easier use we suggest to move the file to the memory card's root.

To load a calendar by default, you must modify the file dschedule.conf with a text ditor and insert the path of the file File:.

This file must be in the same directory of the program on the memory card.

Save the calendar

To save the calendar you must click on the S button. The program will ask you the path where to save the file.

Note: If the file already exist the program will overwrite it.
