Scaling works correctly with the Windows variant, which uses AVI files,
but the DOS variant uses Robot videos, and the way scaling is done
there is different, and is not working yet with KQ7 DOS. Nonetheless,
both versions are included in the game, so it's not a major issue.

reg32_t was a transitive solution, before reg_t's were
adapted to use 32-bit addresses internally, and before
support for SCI3 was added. It was introduced as another
way to handle large script offsets in SCI3, and was only
used for the program counter (PC). It's no longer
needed, as we now support SCI3 script offsets using
reg_t's, so we can use make_reg32 in all cases where
we need to access offsets over 64KB
|
|
All other SCI games continue using the default scaler.

To enable the optional content censoring mode, Phant2 looks
for a RESDUK.PAT file, which is normally placed by the game's
installer if the user chose to enable censorship. If the file
exists, the game reads an unlock password out of the file and
asks the user to enter the password when starting a new game to
create an uncensored game, or to click a "less intense" button
to start the game with censoring. The censorship state of the
game is then persisted in the save game file, and installations
with the RESDUK.PAT file need to enter the password again in
order to restore any of the uncensored saves.
Since we do not have an installer that can enable this feature,
add a game option toggle to enable/disable censoring (for the
releases that have the optional censorship mode) instead so the
censored content feature is available for anyone that wants to use
it. This flag is restored from ScummVM whenever a save game is
loaded, so it can be toggled on or off at any point without
needing a separate save game, unlike in the original interpreter.

1. Added a new game option for linear interpolation when scaling
video in ScummVM builds with USE_RGB_COLOR;
2. 8bpp videos that put black in a palette index other than 0
(KQ7) should now always render correctly without the earlier
game-specific workarounds which did not work very well;
3. Data from game scripts regarding video size and position are
now ignored, since games always just try to show videos in the
middle of the screen, but frequently get this a little bit
wrong, causing either bad aspect ratios or off-center videos;
4. Builds without USE_RGB_COLOR support will not crash when
attempting to play >8bpp AVIs, like those from KQ7 2.00b.
Fixes Trac#9843, Trac#9762.

This changes the syntax for bpk and logkernel:
Enable breakpoint on kernel call:
bpk FrameOut
Enable logging for kernel call:
bpk FrameOut log
For backward compatibility this has an alias: logkernel FrameOut
Removing a kernel call breakpoint is done with bp_del/bc now.

Calling to SciEngine::syncSoundSettings from GuestAdditions
recurses back into GuestAdditions, which is obviously not
desirable. Even when it didn't manage to cause infinite recursion
(as in SQ6 demo), it would make the UI behave in broken ways (e.g.
the +/- buttons on the music slider in SQ6 would not work because
the UI would just get updated immediately back to the closest
rounded value).

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.

This may come back in the future to deduplicate some gfx code,
but SCI32 had two different inlined ways of doing coordinate
conversions with different rounding methods, so CoordAdjuster32
didn't get used when the graphics system was rewritten.
At the moment, SCI32 code uses the mulru/mulinc methods from
helper.h for scaling up/down coordinates.

This commit implements all of the known plane transitions from
SCI2 through SCI2.1mid games. Because kSetShowStyle is always
called indirectly via the Styler game script, it is difficult to
find all the places where transitions are used. As such,
transitions that appeared to never be used have been added as
stubs which will trigger a game crash with a message to report
what was being done, so any missed transition types can be
identified quickly and then implemented.

Is needed for 80462b3 (Fix auto-saving in the fan-made Cascade Quest)
|
|
This line drawing code lives in a remodelled GfxPaint32 class
that is totally separate from GfxPaint16.

This provides a complete implementation of kDoAudio through
SCI2.1mid, plus partial implementation of SCI3 features.
Digital audio calls shunted through kDoSound have also been
updated to go through the SCI32 audio mixer, though these shunts
are a bit hacky because the ScummVM implementation of kDoSound
does not currently match how SSCI kDoSound is designed.
It is probably possible in the future to just replace the SCI1.1
audio code (audio.cpp) with the new SCI32 code, since the major
differences seem to be that (1) SCI1.1 only supported one digital
audio playback channel (this is configurable already), (2) it
had extra commands for CD audio playback and queued sample
playback.
|
|
SCI32 has its own audio handling code, but audio sync code is the
same as SCI16.

Recently we started to use this as new semantics, although in the past
we used simly <engine>_H. Now these guard defines are consistent with
rest of the files which are used in the engines.
|
|
The information in the wiki was wrong, KQ7 1.51 is always SCI
2.1 early.
|
|
|
|
Currently, only the SCI16 remapping functionality is implemented
(used in the QFG4 demo)
|
|
The demo versions of these games were using a very different engine -
SCI1.1 vs SCI2/SCI2.1. Thus, we split them into different game IDs,
to avoid mixing specific game checks for them, as well as specific
game workarounds, which are different for the demos than the full
versions. Also, the demos should be working when SCI32 is disabled.
For these games, we don't use ADGF_DEMO, to avoid game IDs like
foodemo-demo

- Add "kAnimate fast cast state" to "version" debug command
- Make it possible for script patcher signatures to get fully
used outside of the regular script patcher
- Remove previous fastcast detections and replace them with
a signature heuristic
- Remove object name checking, when fastcast global is set
- Heuristic detects "fast cast" support incorrectly for multilingual
KQ5, but it seems the game never sets the global, so it won't
matter. KQ5 CD (also SCI1 late) has fastcast support.
- Remove hack in GfxView::draw
- Add lots of comments to ScriptPatcher class
This fixes EcoQuest 1 Floppy showing the anemone on top of the
message box (see bug #5170)

Instead of choosing Windows as platform, users can now also simply
click this option for Gabriel Knight 1 + King's Quest 6
Defaults to high resolution graphics
|
|
This means tick-based times are saved to save games, as in SCI32
engine, instead of seconds, which are not accurate enough. It
also means places in SCI engine that need to access game ticks
should do so through g_sci instead of g_system or g_engine.

Thanks bSr43

Graphics palette code was rewritten between SCI1 and SCI2, so
SCI32 palette engine code has been moved to a separate GfxPalette32
class.
|
|
- 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
|
|
It's called "Workarounds"
|
|
At least SQ4 uses #j text prefix as signal for the
interpreter to not use the PC9801 hires font, but
to use the internal low res font instead
|
|
This should fix bug #6717 - "SCI fallback detection assert failure"
|
|
|
|
|
|
at the same time
needs indepth testing
|
|
Also added new debug flag for script patcher
|
|
This ensures that ScummVM's game audio options for speech and subtitles
get updated when they are changed in the game GUI
|
|
This can be found in the KQ collection
