CMS/Gameblaster: add sbtype=gb, fix base addresses other than 220h, fix lack of sound when starting from autoexec, add autodetection (Thanks robertmo and Cloudschatze)
As a safety check...
Also throw out some warnings when loading savegames
with instrument data for a different device (the savegame
incompatibility would be very nice to be fixed, but it is not
trivial.
Currently, Roland MT-32 sound is broken for
SAMNMAX. Just try the intro song with shut off
speech. It is very obvious that it plays with a quite
reduced number of channels compared to the
original interpreter.
Now, due to the not-so-helpful code design (much
of the iMuse code has been drawn into the common
code) it has become increasingly difficult to fix Midi
related thing in iMuse. I have added more and more
crude hacks over time.
SAMNMAX requires more elaborate channel
allocation. To make it happen I have added driver
wrappers for Midi to the iMuse code.
Other than that, I have done only minor cleanup here.
Actually, I would have liked to withdraw much more
of the iMuse code from the common code and move
it to SCUMM (basically all the MidiChannel
stuff which is exclusively used by iMuse. But it turns
out that it is so thoroughly intertwined (the major
blocker here being the AdLib driver) that it requires
more thought and effort and would just distract me
from fixing the SAMNMAX sound.
This will actually read out of bounds in the orginal interpreter, too. I have fixed it to be more in line with the original (the value in question is always treated as unsigned here), but still not do anything harmful.
This was previously disabled implicitly by the missing define
symbols in the SampleRateConvertor module. This has now been enabled
to use the internal rate convertor code.
This was generating undefined macro warnings from GCC when -Wundef
was passed.
Reduce abuse of the property function to set init vars.
Better distinction between drivers to prevent a GM init on
the Mac driver (which could happen depending on the
launcher sound setting).
Continued bug fixing for ticket no. 13460 ("Incorrect MIDI
pitch bending"). This time the AdLib part (which applies
to FM-Towns, too, since it is more or less the same driver).
This fixes the sound when the bird is dropping from the
sky in the DOTT intro.
Also separate the GM code for SAMNMAX a bit after
checking the original code.
This fixes a possible infinite loop in VocStream. It depends on the stream size
matching the size specified in the VOC block headers, but if the size in the
headers is incorrect and larger than the stream size, it will keep trying to
read the stream. This is fixed by adding an end-of-stream check to the error
check.
To implement a MOD variant for the Chewy engine, this commit makes some changes
to make subclassing of the ProtrackerStream and associated Module class easier.
Backyard Baseball 2003 was missing dialog which was lip-synced to
animation. This was due to it using the WAV block alignment as a count
of bytes per sample. This is not true for the IMA ADPCM format used for
speech in Backyard Baseball 2003.
This commit adds a mediator class to decouple the CMS emulator from the engines
that use it. This allows for easier updating or replacement of the emulator or
addition of new emulators. It also enables using the emulator via a callback
mechanism.
This adds a MIDI driver for the Casio MT-540, CT-460 and CSM-1 devices. These
are supported by Elvira 1 and several Sierra SCI0 games as well as Altered
Destiny and Les Manley 1.
