The engine would try to initialize the MidiPlayer for all DOS games, even the
ones that don't use MIDI (Personal Nightmare and Feeble Files demos). This
caused a problem with the new MIDI code, which does not set up the necessary
objects for these games and crashed on a null pointer.
This is fixed by adding PN and FF as exceptions to the if condition guarding
initialization of the MidiPlayer.
Simon1 and Simon2 fade the screen to black whenever leaving a room,
but this can be slow to render on some devices, and for some people
nowadays it can really make the pace of the game quite slow.
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.
The first scene of the Simon The Sorcerer 2 intro uses 3 music tracks. The last
2 are missing from the MT-32 MIDI data set. The original interpreter just stops
playing music after the first track and does not restart until the next scene.
This commit fixes this problem by using the GM versions of these 2 tracks
instead and mapping the GM instruments to MT-32 ones.
The DOS versions of Simon the Sorcerer 2 now use the Miles drivers. AdLib now
sounds like the original does. ScummVM would use the second set of XMIDI data,
written for the MT-32, for GM with instrument remapping. Now the first set is
used, which uses GM instruments and has extra instruments on several pieces.
For all versions music fade-outs have been added during screen fades.
MIDI music is now paused by pausing the parser(s) instead of relying on the
mixer streams to stop providing callbacks. This gives more consistent behavior
as external MIDI devices or softsynths now also pause playback.
Muting sound now sets the volume to 0 instead of pausing playback.
Just walking around the castle fixing bugs as I find them, e. g.:
- make decompression routine safer (this could write a couple of invalid byte in at least one case)
- also support compressed data header without actual data (required in the kitchen scene when killing the evil cook)
- fix some graphics/palette related glitches
- Add dual layer graphics display to display the Japanese characters in their proper (double) resolution on top of the graphics. The original actually uses text mode.
- Adapt mouse handling to dual layer code.
- For consistency I got rid of all direct calls to _system->lockScreen() and _system->unlockScreen(), even in the sub engines that aren't affected. I find it easier to debug and to maintain this way.
This flag is removed for a few reasons:
* Engines universally set this flag to true for widths > 320,
which made it redundant everywhere;
* This flag functioned primarily as a "force 1x scaler" flag,
since its behaviour was almost completely undocumented and users
would need to figure out that they'd need an explicit non-default
scaler set to get a scaler to operate at widths > 320;
* (Most importantly) engines should not be in the business of
deciding how the backend may choose to render its virtual screen.
The choice of rendering behaviour belongs to the user, and the
backend, in that order.
A nearby future commit restores the default1x scaler behaviour in
the SDL backend code for the moment, but in the future it is my
hope that there will be a better configuration UI to allow users
to specify how they want scaling to work for high resolutions.
- 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
This also removes the dependency of engines on the event recorder header
and API, and will make it easier to RandomSources that are not properly
registered.
The regression affected AGOS and maybe some others; specifically,
the real MidiDriver would have been deleted twice -- I previously
missed that the Engine instances takes care of freeing the real
MidiDriver, not the MidiPlayer wrapping it.
This commit should clarify the ownership of the real MidiDriver for
most pseudo MidiDrivers.
Many engines follow the advice in audio/midiparser.h and create a
"pseudo-MidiDriver" subclass. But MidiParser really only needs a tiny
subset of the MidiDriver capabilities, namely those found in
MidiDriver_BASE. So we try to subclass from that whenever possible; this
allows us to remove many stub methods, and enables further future
simplifications.
