High-resolution native Macintosh fonts are now supported in the
following games when the game's executable is present:
- Castle of Dr. Brain
- Freddy Pharkas
- King's Quest 6
- Leisure Suit Larry 1
- Leisure Suit Larry 5
- Space Quest 1
And in these games when classicmacfonts.dat is present:
- Leisure Suit Larry 6 (floppy)
- Quest for Glory 1
This is based on the work done for GSoC by @taylorzhancher in PR #3256
Highlights:
- TTS has been hooked globally onto places where text is shown
- TTS is currently performed for textboxes and button texts
- TTS stops when text windows are disposed (which enhances the in-game
experience)
- No game-specific logic has been added
- This hasn't been extensively tested with all SCI16 games yet
- There will be cases that are not handled properly yet
- The TTS functions have been grouped under a SciTTS class
This was introduced as an extra mechanism of patching game scripts.
However, it's completely hardcoded with offsets for specific game
versions, with no endianess handling. Furthermore, the only patch
it's used for at the moment (input prompt for SQ3) has no visible
changes.
The SCI engine's script patcher has pattern matching functionality,
which allows it to be used in a variety of game versions. Furthermore,
it supports endianess handling for BE versions. Thus, it makes no
sense to keep a separate and complex script patching functionality
for a single patch that is hardcoded for a single game version with
no actual change in functionality. Since this is a fan patch, all of
these script changes can be added as part of the patch without any
changes to the engine code. We've discussed this with @sluicebox and
decided to remove all of this code, which should not have been part
of the engine's codebase because it clashes with the existing script
patcher
Originally from e66ea0827a, this part has
been added separately because of the major changes in the detection
code since the original commit was written.
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.
This avoids an issue with MSVC where if (non-SCI) "graphics/font.h" is
included through another include file from the SCI engine root, it finds
"sci/graphics/font.h" first and uses that instead.
The current patch mechanism allows only replacing intructions in current
scripts, but not adding new instructions out of nowhere.
Thus, issue like #9646 is about to be closed as WONTFIX.
This new mechanism adds a hook on vm.cpp, before executing opcodes, and
if required, executs a new code.
It solves one of the issues of #9646, the others can be solved as well using that mechanism.
The resource patcher can be used to patch non-script resources
like views, maps, sounds, etc. It is more primitive than the script
patcher in that it does not use signatures for safe and automatic
patch relocation, but it does at least allow existing resources to
be grown if needed.

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 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.
Remap would crash SCI2.1early games with 19 remap slots, and
did not actually work in most cases in SCI2.1mid+ games.
The SCI16 implementation was moved to its own separate file but
was otherwise touched as little as possible, so may still have
similar problems to the SCI32 code.
1. Split SCI16 and SCI32 code into separate files
2. Use -32 prefixes for SCI32 code and no prefix for SCI16 code,
where possible, to match other existing code
3. Avoid accidental corruption of values from the VM that may be
valid when signed or larger than 8 bits
4. Added documentation
5. Add missing remap CelObj calls
6. Inline where possible in performance-critical code paths
7. Fix bad `matchColor` function, and move it from GfxPalette to
GfxRemap32 since it is only used by GfxRemap32
8. Fix bad capitalisation in getCycleMap
9. Remove unnecessary initialisation of SingleRemaps
10. Update architecture to more closely mirror how SSCI worked
11. Clarify the purpose of each type of remap type (and
associated variable names)
12. Split large `apply` function into smaller units
13. Fix buffer overrun when loading a SCI2.1early game with remap
14. Remove use of `#define` constants
15. Warn instead of crashing with an error on invalid input (to
match SSCI more closely)
16. Change the collision avoidance mechanism between the RemapType
enum and remap kernel functions
17. Add save/load function
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.
Phantasmagoria's scripts keep polling for the existence of the savegame
index file and request to read and write it using the same parameters
when opening it. The index file is closed and reopened for every save
slot, which is slow and can be much slower on non-desktop devices.
Also, the game scripts request seeking in writable streams and request
to expand the existing index file.
To provide this functionality and to reduce constant slow file opening
and closing, this virtual class has been introduced
This refactoring reduces a lot of code duplication, allows for better control,
makes the code more readable and allows us to remove a lot of now unneeded
workarounds
SciEngine class
- Robot videos are now shown in frameOut(), like they should, and kRobot(sync) is only
used for syncing with the game scripts
- Hooked video playing into the "play_video" console command
