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.
