NDS:Identifying Firmware Version with PictoChat

It is possible to identify the revision of your Nintendo DS/DS Lite firmware by purposely crashing PictoChat via way of removing a DS/GBA cartridge while the application is running.

Instructions

 * 1) Place a DS or GBA cartridge in their respective slot. It is not clear whether or not Flashcarts will work!
 * 2) Turn on your DS/DS Lite by holding down the power button, ensuring it boots to the menu.
 * 3) Launch PictoChat and enter any chat room.
 * 4) While in the chat room, remove the cartridge from the slot.
 * 5) Take note of the way in which your DS/DS Lite crashes.
