My commit 0e734722 causes lockups in SCUMM (sometimes) and SCI (very often). I didn't like the way I had fixed this before, but in the end I now had to do it in a similar way.
Timers should be reset only the first time the enable flag is sent. This also requires some updates to drivers which didn't send these flags accurately.
- Increase internal sample rate to dividers of the actual chip clocks and fix other related things. This seems to improve certain sfx/noise generator like sounds. The performance still seems to be okay.
- Fix feedback glitch that caused some noise with certain instrument patches when playing short notes.
- Fix squarewave sound glitch (mute channels when volume is zero; this could also cause unnecessary noise).
- Some cleanup.
The previous fix did not work as the forbidden exception had no effect
since scummsys.h and thus forbidden.h had already been included prior
to the fluidsynth header being included. This also meant that undefining
the exception define after the header would have had no effect anyway.
This new solution was suggest by eriktorbjorn on bug #11278 and should
avoid the need to add an exception which would persist over the entire
source file.
- move mac, pc speaker and fm-towns ims sound drivers into separate directory
(AdLib and MT32/GM drivers are still too entangled with common code to be moved so easily, especially MT32/GM. It would require lots of changes to the common code and possibly to all engines using the MidiDriver class. So I leave that for now.)
Fixes warning C4530: C++ exception handler used, but unwind semantics are not enabled
by disabling exceptions in the STL since ScummVM doesn't support them
This is another warning of the use of memset to clear a non-trivial
structure / class. This can be removed since the structure is cleared by
the constructor which will be called by the "new" so clearing this again
is redundant.
Apart from some basic cleanup this commit reverts a somewhat unfortunate design decision I made. The Kyra/Hof/Lol PC-98 sound drivers shouldn't inherit from the emulator. This commit separates the driver from the emulator putting some common interface in between. This should allow easier implementation of other PC-98 sound drivers.
(This is basically an unnecessary emulation of a hardware limitation. EOB II will try to load approximately 70 KByte of samples for the outro sequence, which would lead to some missing sounds with the 64 Kbyte limit).
The function signature for these functions was changed from (char *) to
(const char *) in the v1.1.7 release, so compiling against
Fluidsynth v1.1.6 or earlier requires the copying of the strings to
prevent compilation errors such as "error: invalid conversion from
'const char*' to 'char*'".
Normally, we would break compatibility with older versions as platforms
should be using the latest Fluidsynth v1.X release of v1.1.11.
However, since this is trivial to fix and prevents breakage for legacy
platforms, am restoring the string duplication with scumm_strdup().
Apart from this, we should look at the Fluidsynth v2.X releases
currently in RC testing as the API is now changed for this.
As discussed on the mailing list we should use title capitalization
only for push buttons and tabs and use sentence capitalization for
everything else.
