zlib is used when available and falls back on gzio.
This allows performance improvements as our CRC32 and gzio
implementations are slower than base zlib.
As zlib is available when libpng is present, this is sensible to
benefit from it.
This change introduced several character animation regressions in the
game, which may seem as a worse experience than the original issue with
the pirate dialogue, for most end users (Trac#13997).
This reverts commit eb851041ed.
This adds detection entries for the German and French versions. All language
versions except Russian use WAV sound effects and GM SMF MIDI data, so the
platform is changed to Windows. These versions also contain the MT-32 MIDI data
in XMIDI format, so support for this is added as well. Finally, the MT-32 track
10 workaround has been updated to deal with these versions.
Adds detection entries for the new versions in the 25th Anniversary editions.
The remaining language versions are already detected.
To use the 25th Anniversary versions you have to copy the files from the
subdirectory of the language you want to use to the main directory, then detect
the main directory; or just detect without copying for English CD.
GOG has not included the AdLib instruments file with their release of Simon the
Sorcerer 1 DOS version. The game would not start in ScummVM when this file was
missing and AdLib was selected. Added a fallback to the generic AdLib driver
with built-in instruments.

Also made the Windows version start with AdLib if an OPL2-only emulator is used.
When the noop flag was set on a MIDI event by the AGOS Simon 1 Windows or GMF
parsers, it would not be cleared when parsing the next event, leading to all
subsequent MIDI events being ignored.
Fixed this by setting the noop flag to false when it is not applicable to a
MIDI event.
When using this option with Simon 1, Simon wouldn't be cleared from the
bottom of the screen, if pressing Esc when Simon starts walking through
the screen right after the "Simon the Sorcerer" title is printed, at the
very beginning of the game.
Triggering the clearSurfaces() code even when _neverFade is enabled
solves this problem.
Fixes a mistake of mine in commit 802caa4c39.
Waxworks DOS has both digital and limited MIDI SFX. The game scripts use two
different opcodes for trigging digital and MIDI SFX; if a sound effect has both
a digital and a MIDI version, both opcodes are triggered. When digital SFX are
active, ScummVM would try to handle both the digital and the MIDI opcode by
playing a digital SFX. This would crash the game if the MIDI SFX ID was invalid
as a digital SFX ID. Strangely enough, this bug also seems to affect the Amiga
version. Apparently both opcodes are still in the scripts of this version, even
though it does not support MIDI at all AFAIK.
This commit fixes the issue by only playing the MIDI SFX if digital SFX are
turned off and ignoring them otherwise.
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 commit enables the Accolade AdLib driver's OPL3 mode for Elvira 1. It adds
some extra notes, most notable in the intro track. A small fix is applied to
one of the instruments in the intro track to make it work properly with this
mode.
Some Elvira 1 music tracks would not loop properly. These tracks make use of
the loop event, which stores the position in the MIDI stream where the parser
will later loop to. An event is optionally preceded by a delta, as indicated by
the _noDelta property of the parser. However, when looping, this flag was not
set to the state matching the event after the loop point. This would sometimes
cause the parser to interpret a MIDI event as a delta, which would break the
parsing.
This is fixed by storing the _noDelta flag with the loop data and setting it
to the stored value when looping.
This change improves the accuracy of the timing of the AdLib SFX of Elvira 2
and Waxworks. The frequency of the SFX script timer is now synchronized with
the callback timer of the AdLib driver, which makes the timing of the OPL
register writes match that of the original interpreter.
