 * A lesson in savage engines
 *
 * The various incarnations of the savage engines are a complicated story.
 * I've done some research and wrote this little guide to help clarify things.
 * There are 3 basic parts to the savage - 2D, 3D, and streams.
 * There are 3 basic 2D cores: Savage3D, Savage4, 2000.
 * There are 3 basic 3D cores: Savage3D, Savage4, 2000.
 * There are 2 basic Streams engines: old, new/mobile.
 *
 * ****** 2D Cores ******
 * The different 2D cores have slightly different COB and bitmap descriptor layouts
 * among other things.  The 2D core breakdown looks like this:
 *
 * "Savage3D" 2D core:
 *  - Savage 3D
 *  - Savage MX
 *  - Savage IX
 *
 * "Savage4" 2D core:
 *  - Savage4
 *
 * "2000" 2D core:
 *  - Twister
 *  - ProSavage
 *  - ProSavage DDR
 *  - Savage 2000
 *  - SuperSavage
 *
 * ****** 3D Cores ******
 * The "savage4" 3D core has some slight variations within the series, but is 
 * the same for the most part.  The 3D core breakdown looks like this:
 *
 * "Savage3D" 3D core:
 *  - Savage 3D
 *  - Savage MX
 *  - Savage IX
 *
 * "Savage4" 3D core:
 *  - Savage4
 *  - Twister
 *  - ProSavage
 *  - ProSavage DDR
 *  - SuperSavage
 *
 * "2000" 3D core:
 *  - Savage 2000
 *
 * ****** Streams Engines ******
 * The "new/mobile" streams engine is really basically just 2 streams engines 
 * with some tweaks; one for each head (the mobile savages support dualhead).   
 * The streams engine in the Savage 2000 is similar to the "new/mobile" engine, 
 * but with slight differences in registers.  The streams breakdown looks like 
 * this:
 *
 * "old" streams:
 *  - Savage 3D
 *  - Savage4
 *  - Twister
 *  - ProSavage
 *  - ProSavage DDR
 *
 * "new/mobile" streams:
 *  - Savage MX
 *  - Savage IX
 *  - SuperSavage
 *  - Savage 2000
