they are CPU register pointers :) you can do funky stuff like
overclocking, special hardware dependent code (ie: tweak
the LCD controller into grayscale etc).. they are documented
inside the CPU manuals. :)
keep in mind.. they may change (pointer values) from device to
device.. there are three CPU's being used right now..
