    1.17 +/* Why the funny register names?
    1.18 +
    1.19 +The register names do not match the names in the official GBA
    1.20 +documentation.  I choose the names that seem most logical to me.
    1.21 +In addition, I do slick macro tricks with the VRAM addresses for
    1.22 +maps and the like and with registers that control timers, DMA,
    1.23 +and backgrounds.  The gba.h that comes with wintermute's libgba
    1.24 +incorporates some but not all of these tricks.  In addition,
    1.25 +the names in gba.h for the sound registers aren't descriptive
    1.26 +at all.
