Fixes Audio button in control panel getting out of sync with
the message mode set by ScummVM.
|
|
This fixes issues with Bridge and Backgammon. Now, Hoyle 5 and its
variants should be in a very good state for testing
|
|
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

This update should give the game the default mix it receives in
Windows. If necessary, the half-volume audio bug in the DOS
interpreter can be added as an additional hack for this game, since
there are still some sub-par audio mixes that might need additional
correction (like Curtis talking to Blob when taking her out of the
cage in his apartment at the start of the game) which were also
bad in the Windows version of the game.
Fixes Trac#10165.

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.

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.

SCI3 includes four new opcodes:
* op_info[0x26][0] puts -info- flag in accumulator
* op_infoSP[0x26][1] pushes -info- flag to stack
* op_superP[0x27][0] puts -super- reference in accumulator
* op_superPSP[0x27][1] pushes -super- reference to stack
The implementation of these opcodes was correct already, but the
opcode names given were a bit misleading (the value is not always
stored to accumulator), and magic numbers were used for these
opcodes in places.
A review of the opcode table in Phant2 indicates that there are
no other new opcodes for SCI3.
|
|
For whatever reason, this game uses a different global for
specifying the text speed.
|
|
1. pushi opcode now displays decimal value and selector value (if
one exists) in-line
2. lofsa, lofss, and super opcodes now display resolved
object/class names
3. Opcode arguments are visually aligned

The ExecStack constructor set argp[0] to argc before. This is now moved
to the caller, to make this action more explicit.
|
|
ExecStack now stores the kernel call number as well as the subfunction.
This allows kStub and backtraces to log the actual subfunction called.
The kernel call number in ExecStack used to be stored in the
debugSelector field. It now has its own field, to avoid confusion.

This is needed for future support of large SCI3 scripts. The program
counter is isolated and does not interfere with other parts of the VM,
plus it does not get stored in saved games, so it's pretty straightforward
to convert
|
|
No functionality change has been made with this commit. This avoids
setting and getting the reg_t members directly, and is the basis of any
future work on large SCI3 scripts (larger than 64KB)

- Removed the CallsStruct intermediate stack. Calls are inserted directly
in the execution stack
- Added a constructor for the ExecStack struct and removed
add_exec_stack_varselector() and add_exec_stack_entry()
