5 months ago The currently failing tests are:
- 8: Length counter behavior while powered off
- 9: Wavetable RAM read behavior while playing
- 10: Wavetable trigger behavior while playing
- 11: Register behavior after power off/on
- 12: Wavetable RAM write behavior while playing
8 and 11 were easy to fix - they depend on the CPU being able to write to the length counters while the APU is powered off (on DMG only; CGB blocks the writes based on cgb_sound).
9, 10, and 12 seem like they will be much more difficult to fix as they depend on extremely precise CPU/APU timing.
