When a byte is written to port 0x06 on the Game Gear, the PSG output is affected as follows:
| Bit | Channel | Side |
|---|---|---|
| 0 | 0 | Right |
| 1 | 1 | Right |
| 2 | 2 | Right |
| 3 | 3 | Right |
| 4 | 0 | Left |
| 5 | 1 | Left |
| 6 | 2 | Left |
| 7 | 3 | Left |
If a bit is set, the corresponding channel is output to the
corresponding side. So, 0xff outputs all channels to all sides, 0xf0
outputs to the left side only, etc.
