Allows testing the speed throttler for possible improvements
and to demonstrate what it affects and what it doesn't.
`speed_throttle 0` disables kGameIsRestarting throttling.
(Except for game-specific workarounds.)
This command is possible due to several recent cleanups of other
throttling mechanisms that overlapped and were absorbed by this one.
Restore object names in QFG1VGA workarounds that were removed to
accommodate the Mac version. Instead, don't match object names
on games that are known to not have them, since there are several.
Fixes workarounds not being applied to HOYLE4 Mac and LSL6 Mac.
Fixes QFG4 bug #10765. It's preferable to have sanity checks in the
code, rather than crashing due to invalid draw rectangles from buggy
game scripts. It's no use checking which specific interpreter versions
had sanity checks and trust the game scripts of the other interpreters.
Thus, it's easier and safer to always enable these sanity checks.
This was happening in games with game scripts that control the
master volume themselves by applying the master volume to each
channel sent to the kernel, instead of relying on the kernel to
manage the master volume for them.
Upon investigation of Sound code across SCI32 games, it was
determined that there are actually (at least) 3 different
revisions, not just a single SCI2.1 version. This patch only
changes the parts of Sound code that are relevant to the correct
use of Audio32.
Fixes Trac#9736, Trac#9756, Trac#9767, Trac#9791.
1. Unlocking all resources of a type using a resource ID of -1 is
gone in SCI32;
2. Audio locks need to be serialized starting in GK2 for the game's
modified kDoAudio(1) call;
3. Audio locks in SCI3 must work more like SSCI, since at least
Lighthouse's `BackMusic::fade` method will attempt to unlock
audio that was never locked by a script. In SSCI (and now in
ScummVM too) this is a no-op; previously in ScummVM, it would
remove Audio32's own lock on the audio resource, resulting in a
use-after-free;
4. kDoAudio(1) starting in GK2 returns the number of active
*not-in-memory* channels being played, not the total number of
active channels.
Fixes Trac#9675.
Sometime during SCI2.1mid, the palette manager was changed to
save and restore the source palette, and to add in-game gamma
correction. Previously, only the vary start and target palettes
were saved, and gamma correction was only configurable in SSCI by
editing RESOURCE.CFG.
This patch includes enhancements to the ScummVM integration with
SCI engine, with particular focus on SCI32 support.
1. Fixes audio volumes syncing erroneously to ScummVM in games
that modify the audio volume without user action (e.g. SCI1.1
talkies that reduce music volume during speech playback). Now,
volumes will only be synchronised when the user interacts with
the game's audio settings. This mechanism works by looking for
a known volume control object in the stack, and only syncing
when the control object is present. (Ports and planes were
researched and found unreliable.)
2. Fixes audio syncing in SCI32 games that do not set game
volumes through kDoSoundMasterVolume/kDoAudioVolume, like GK1,
GK2, Phant1, and Torin.
3. Fixes speech/subtitles syncing in SCI32 games that do not use
global 90, like LSL6hires.
4. Fixes in-game volume controls in SCI32 games reflecting
outdated audio volumes when a change is made during the game
from the ScummVM launcher.
5. Fixes SCI32 games that would restore volumes from save games
or reset volumes on startup, which caused game volumes to be
out-of-sync with ScummVM when started.
6. ScummVM integration code for audio sync has been abstracted
into a new GuestAdditions class. This keeps the ScummVM-
specific code all in one place, with only small hooks into the
engine code. ScummVM integrated save/load code should probably
also go here in the future.
Fixes Trac#9700.
PQ4CD and several other games contain a hack in two renderer
methods to avoid rendering invalid screen items with zero or
negative-dimension target rects. This prevents PQ4CD from
crashing during the fifth phase of target practice.
Pseudo mouse was functionality in SCI1+ games, that allowed the
user to control the mouse via keyboard cursor keys.
This new class only worked, when a tiny difference inside
the keyboard driver happened on kMapKeyToDir calls. We previously
tried to enable this behavior depending on cursor type, but
this didn't work correctly (Larry 5 for example was not detected
as such, but had PseudoMouse support).
- Detection works via signatures (couldn't find a better way)
- new kString subcalls were introduced SCI2.1 LATE
- kString now has signatures and is split via subcall table
- kString fix, so that KQ7 doesn't crash, when starting a chapter
- Sci2StringFunctionType removed, because no longer needed
Fall back to the DOS soundtracks in Windows CD versions if the user picks
a non-General MIDI music device, as the Windows tracks only contain MIDI
music
This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
makes polish lsl1 work (its game superclass name got translated, so no "Game" object available) - bug #3037194 thx to dam-soft for his patient help

The demo really uses kGetMessage and not kMessage. We now detect which version of the message function is used. Thanks to Walter for pointing this out.
