Unlike SCI16 games, the location of data within SCI32 patch files
is calculated on a per-resource-type basis by the game engine,
instead of by reading byte 1 of the patch file.
This type in SSCI corresponds to Wave resources, but since ScummVM
does not differentiate between Wave and Audio resources, just say
it's an Audio resource type, not an Invalid resource type.
Phant1, PQ:SWAT, GK2, and Phant2 all have different audio maps
and audio volumes on each CD. In order to make this work within
ScummVM, where CDs are never swapped, each RESOURCE.AUD for these
games must be renamed to RESAUD.00x and each RESOURCE.SFX renamed
to RESSFX.00x.
Several times I have run into this code and had to take a minute
to remind myself that the call to remove from the LRU on find is
not wrong, so it seemed to deserve a comment.
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.
Removed the superfluous initForDetection() function, which was not
updated in commit 2f17ba2b0a and
caused the fallback detector to crash because of uninitialized
variables
A single picture in SCI32 is often larger than the 256KiB limit,
meaning that the cache is useless for these games -- which is bad,
because the renderer works directly off raw resource data so it
must be decompressed and in-cache for rendering performance to be
acceptable.
- 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
This contains the sync data in the Windows version of KQ6CD.
Note that currently the sync36 resource is 2 bytes bigger
(it contains 2 bytes from the RAVE resource). Some test code
has also been added to dump the RAVE sync resources
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)
These were introduced in 4f6d42d.
The odd comment dates back to FreeSCI, as far as our history goes, and
seems to be a leftover from an old refactoring during FreeSCI's history
On some systems, passing signed chars to macros like isspace() etc. lead
to a runtime error. Hence, mark these macros as forbidden by default,
and introduce otherwise equivalent alternatives for them.
