10  \brief Definitions for using the Puru Puru (Jump) Pack.
11 
12  This file contains the definitions needed to access maple jump pack devices.
13  Puru Puru was Sega's internal name for the device, hence why its referred to
14  in this way here.
15 
16  This driver is largely based off of information provided by Kamjin on the
17  DCEmulation forums. See
18  http://dcemulation.org/phpBB/viewtopic.php?f=29&t=48462 if you're interested
19  in the original documentation.
20 
21  Also, its important to note that not all Jump Packs are created equal. Some
22  of the stuff in here does not do what it seems like it should on many
23  devices. The "decay" setting, for instance, does not seem to work on Sega
24  Puru Purus, and actually makes most (if not all) effects do absolutely
25  nothing. Basically, its all a big guess-and-test game to get things to work
26  the way you might like. Don't be surprised if you manage to set up something
27  that does absolutely nothing on the first try.
