Yesterday, another revision to the firmware was predicted. Today, it was revised. Version 0.0.7 has been updated at the link below. This version allows the computer to reset the internal timer. The purpose of an internal timer, which can be synchronized, was to reduce cheating. In some games, it would be possible to take a “learning” remote and program it with the tagger’s code. Then, an unscrupulous player could repeatedly transmit the code for his or her tagger even if the tagger was disabled. It would also allow fully-automatic operation. If players are expecting a time-stamped signal those copied signals would be ignored.
If the taggers were all connected to a wireless network, Wifi for example, it would be possible to ignore copied signal but network traffic would increase. This functionality provides a level of security in the game, although it is far from foolproof. Programmers who do not wish to take advantage of this functionality in their games can easily ignore the feature.
A list was made of the data swapped between the tagger and computer. This will be vital for anyone who wants to implement a program with this firmware. At this point in the firmware, it should be possible for someone to build a functional laser tag game with the code provided here.
