This adds support for the AdLib and MT-32 sound effects in Elvira 2 and
Waxworks. It adds an option to the UI to toggle between sampled and
synthesized SFX. It also adds the following enhancements:
- AdLib OPL3 mode for Elvira 2, Waxworks and Simon 1 floppy demo. This can be
selected using a new UI option.
- Mixed AdLib/MIDI mode for Elvira 2 and Waxworks.
- Implemented "monophonic chords", a feature of the original MIDI code which
would play only the highest note of a chord on AdLib. Most noticable in the
Waxworks music.
- Added UI option to select Simon 1 DOS music tempos.
- Rewrite of the AdLib and MT-32 drivers to remove duplication and make use of
features of the standard multisource drivers.
- Refactored MidiPlayer to standardize interface and remove code moved to the
drivers and parsers.
This updates the Simon 1 DOS AdLib driver and adds an AdLib driver for Windows.
The DOS driver now has OPL3 support, which eliminates the note cut off that
frequently occurs on an OPL2. It also allows for some limited use of stereo.
The driver now plays the floppy SFX accurately compared to the original
interpreter. It also implements multisource functionality, allowing for
separate volume control for music and SFX for the floppy version.
The Windows driver just maps the MT-32 instruments of the Simon 1 MIDI data to
the equivalent GM instruments.
This commit adds MIDI parser subclasses for the Simon 1 GMF format and for the
SMF variant used by the Windows versions of Simon 1 and 2.
The GMF format was handled by the SMF parser, which can now be removed from
that class. It also fixes the tempos not matching the DOS interpreter.
The Simon Windows SMF variant was handled in the AGOS midi class. Moving it to
a separate parser allows for some cleaner code in that class. It now also
corrects the tempos to match those of the DOS interpreter.
For each engine:
- Make a new folder detection
- Move detection-related files inside the folder
- Add a new module "enginename/detection"
- Add DETECT_OBJS here
- Adjust the normal engine module to remove detect_objs
- Adjust every file for the new changes.
- Move AGOSGameDescription -> detection.h
- Move obsoleteGameIDsTable -> obsolete.h
- Both the above points are because the detection needs them, as well as the engine.
- By moving to headers in this pattern, we avoid many unnecessary inclusions and keep everything clean.
- both known variants are supported (INSTR.DAT + MUSIC.DRV)
- INSTR.DAT/MUSIC.DRV holds channel mapping, instrument mapping, etc.
- fixed bug inside S1D MidiParser, that ruined some instrument changes
0xFC header was seen as 2 byte header, but it's 4 bytes in Elvira 2
and 5 bytes in Waxworks / Simon 1 demo
- dynamic channel allocation for the MUSIC.DRV adlib driver is not
implemented atm, simply because at least the demos of Waxworks and
Simon 1 do not use this feature
- sound effects of Waxworks are not implemented atm
- note: the game "Altered Destiny" uses Accolade INSTR.DAT variant too
