| paulo@0 | 14 /* Why the funny register names? |
| paulo@0 | 15 |
| paulo@0 | 16 The register names do not match the names in the official GBA |
| paulo@0 | 17 documentation. I choose the names that seem most logical to me. |
| paulo@0 | 18 In addition, I do slick macro tricks with the VRAM addresses for |
| paulo@0 | 19 maps and the like and with registers that control timers, DMA, |
| paulo@0 | 20 and backgrounds. The gba.h that comes with wintermute's libgba |
| paulo@0 | 21 incorporates some but not all of these tricks. In addition, |
| paulo@0 | 22 the names in gba.h for the sound registers aren't descriptive |
| paulo@0 | 23 at all. |
