When debugging, I'm constantly inspecting the SCI VM registers and thought this would be a great command to have an alias for.
I am proposing the following alias: `reg` for the command `registers` and also updated the help docs.
These commands have already been implemented by a previous committer.
This commit simply adds the commands to the console debug `help` command for the SCI engine.
Fixes several problems with the SoundResource class:
- Constructor doesn't fully initialize object if resource doesn't exist
- Destructor crashes if object not fully initialized
- Constructor has no mechanism to report failure
- Callers believe failure is reported by constructor returning null
- SoundCommandParser::initSoundResource attempts to pre-detect failure
insufficiently in the absence of a formal mechanism.
SoundResource now always fully initializes, the destructor no longer
accesses uninitialized memory, and an exists() method has been added
which callers now test.
SQ6 Mac can now progress past the main menu.
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 flag is removed for a few reasons:
* Engines universally set this flag to true for widths > 320,
which made it redundant everywhere;
* This flag functioned primarily as a "force 1x scaler" flag,
since its behaviour was almost completely undocumented and users
would need to figure out that they'd need an explicit non-default
scaler set to get a scaler to operate at widths > 320;
* (Most importantly) engines should not be in the business of
deciding how the backend may choose to render its virtual screen.
The choice of rendering behaviour belongs to the user, and the
backend, in that order.
A nearby future commit restores the default1x scaler behaviour in
the SDL backend code for the moment, but in the future it is my
hope that there will be a better configuration UI to allow users
to specify how they want scaling to work for high resolutions.
See matchKernelBreakpointPattern() for samples. The main envisioned use is
DoSound*,!DoSoundUpdateCues
to match all DoSound sub-functions except DoSoundUpdateCues.
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.
Bad resources that need to be blacklisted sometimes seem to have
the same size as good resources. In such cases, the bad resources
can be identified by hash instead. Adding a hash output to
resource_info will make it easy for users to provide the hash of
questionable resources inside of resource bundles that we do not
have access to.

ObjMap owns Objects, so every time this map gets copied instead of
referenced, it creates a copy of every single object in the
associated script. This is expensive, and it breaks things like
the `Object::syncBaseObject` call in savegame.cpp, which hasn't
actually been doing anything since
58190c36b4 because it has been
operating on copies.
Basically just grepped for getOffset calls being assigned to
uint16s and expanded those to uint32 when they looked trivial.
While some of these changes seem superfluous, at least for the
US/English SCI3 games where potentially impacted game scripts are
not large enough to have a problem with 16-bit offsets (e.g. when
feature detecting the sound type), at least some of these changes
are necessary for correct operation of the find_callk debugger
command in SCI3 games. There should not be a reason why any of
these variables need to be kept as uint16, in any case.
