paulo@0: /* Why the funny register names?
paulo@0: 
paulo@0: The register names do not match the names in the official GBA
paulo@0: documentation.  I choose the names that seem most logical to me.
paulo@0: In addition, I do slick macro tricks with the VRAM addresses for
paulo@0: maps and the like and with registers that control timers, DMA,
paulo@0: and backgrounds.  The gba.h that comes with wintermute's libgba
paulo@0: incorporates some but not all of these tricks.  In addition,
paulo@0: the names in gba.h for the sound registers aren't descriptive
paulo@0: at all.
