- MP3/OGG files are now decoded with dr_mp3 and stb_vorbis via the new
MakoMusic backend.
- Merge src/win/mako.cpp into src/generic/mako.cpp: Windows now uses the
same SDL audio path.
- A single SDL2 audio device mixes FM, BGM and PCM in its callback with
SDL_MixAudioFormat.
- PCM plays through SDL_AudioStream.
- dr_mp3 and stb_vorbis are vendored under deps/ and included from
mako_music.cpp. Warnings for that translation unit are silenced.
ymfm's fm_engine_base::output() contains OPL-specific rhythm code that
accesses m_operator[13]/[17], which is out-of-bounds when instantiated
for OPN (OPERATORS=12). The code is unreachable at runtime because
rhythm_enable() returns false for OPN, but newer clang (emscripten) flag
it statically.
- Now tracing is not a build-time config but a runtime option (`-trace`)
- One command per line, so that traces are not mixed with other outputs
- Send traces to DAP client
- Fix garbled characters in non-SJIS environments
Before this, MIDI playback was done by generating an SMF data stream,
which was then played using platform-specific methods (MCI on Windows,
MediaPlayer on Android, SDL_Mixer on other platforms). However, this
approach had an issue where the Y18 command (which reads loop counts and
markers) did not work correctly.
With this change, the MAKOMidi class now uses the RtMidi library to
control MIDI devices in real-time. This approach was used in the
original "System3 for win32", but has now been made cross-platform.
The dependency on RtMidi is optional. If RtMidi is not available at
build time or a MIDI device is unavailable at runtime, FM synthesis will
be used.
