This code is identical to the kArrayGetData implementation.
|
|
kCelLink exists in SSCI since 2.1mid, but it is only known to be
used in Lighthouse, during the weapon creation puzzle near the end
of the game.

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.

Used by RAMA, when playing a video at the Hub Camp computer at the
beginning of the game (room 1004).

Fixes text scaling gone mad in Phant2.

Different subops have different call signature requirements.

Used by Hoyle5.
Also includes a tiny amount of cleanup in kAddAfter for
consistency with kAddBefore.

Used in Shivers room 35170 when pressing the play button.

transparentColor -> skipColor
displace -> origin
scaledWidth -> xResolution
scaledHeight -> yResolution

Games with custom save code (KQ7, MGDX, PQ:SWAT, Shivers) are not
fully supported yet.

This change invalidates earlier SCI32 save games, which separated
arrays and strings in an incompatible manner. Old save games
contain invalid references to a string segment which no longer
exists, and contain incompatible array structures that lack
critical type information.

These were introduced in SCI3, and are used by RAMA. We don't preload
videos, so we don't really need kPlayVMDSetPreload, but
kPaletteSetGamma may need an implementation.
With these two stubs, the main menu of RAMA is working again

Fixes (at least) the native SCI save dialogs.

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.

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 kernel call seems only to be used by KQ7 1.51 (which was
Windows-only) to send warnings to the user.
It was easy enough to do a basic implementation in the ScummVM
GUI rather than just make it an empty call, so now it is a thing.
|
|
These should be all the actually used subfunctions.

Replaces unused kernel calls to use kEmpty, and set correct
signatures for SCI32 kernel calls.

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.

The SCI16 versions do not implement the scaling algorithm used
by SCI32 so would be off by one in some cases.
|
|
applyRemap() is still not finished, so nothing is actually visible yet

|
Not all SCI2.1late/SCI3 function signatures are fully known yet,
but all subops are now represented in the kernel tables.
