bwmott d902a9b237 Added a few comments and updated the "high-water" mark for the sound
register queue so that it's based on the fragment size.  This should
help ensure the queue isn't cleared for larger fragment sizes.

stephena 50767f4bb1 - Fixed some compile warnings under gcc.
- Adding better error checking to the mainSDL class (SDL_WasInit),
thanks to Joshua Rodman.

 - Removed the bufsize argument, since it's no longer used.

bwmott 2e09e2c00c A fairly major rewrite of the class to improve the sound support. The
enhanced sound in games like Pitfall II and Quadrun should be working
now.  Also the overall sound in most has should be improved since the
TIA sound register writes and sample generation are somewhat synchronized.

stephena c9f9448e77 Integrated the Settings/SettingsWin32 classes into the StellaX frontend.
That means I was able to ditch the ugly INI file code, and use the Settings
classes directly.  It also means I don't have to pass many options to Stella
commandline program through commandline arguments, since they'll already
be in the config file.

This is the beginning of fully integrating the Stella commandline program
with the StellaX GUI.  It won't happen for this release, but in later
releases these may become one program again.

stephena 6f9618a4da Removed dependency of Console from the Settings class. It didn't make
sense for the Settings class to have to depend on Console, especially
since I plan to use the Settings class in the Windows frontend.

Removed the snapshot filename code from the individual SettingsXXX classes,
since it was redundant.  Instead, added a ::fileExists() method, which
is the only thing that was really platform-specific about the code
anyway.

Linux and Windows ports have been updated.  The Mac port will have to be
updated to work with this.

stephena af928f7dad Made the Driving class actually refer to Driving Controller events
instead of joystick events.

This bug has been present in the codebase for over 3 years (at least).
Thanks to Mark Grebe for pointing it out.

This means that you will no longer be able to use a gamepad/joystick
for both joystick *and* driving controller events at the same time;
you'll have to map a particular device to either an internal Atari
joystick *or* an internal Atari Driving Controller.

This also means that the Driving Controller remapping now actually
works.  Previously, it didn't do anything.

stephena 1753bb8b48 Removed the event mapping of 'Escape' ==> 'Quit Emulation' for the MacOSX

To any Mac users who are testing the code at this point; you'll have to
delete your Stella config file for this change to take effect.

stephena a0f6eaa4ff Start of updating the StellaX binary for use with the commandline
Stella program.  Right now it doesn't do anything, but at least it
compiles :)

Since most options can be toggled at run-time in the Stella binary,
and most of those changes are saved by Stella itself, I'm probably
not going to add many options to StellaX (only the ones that can't
be changed through Stella itself).  The next version will hopefully
have more configurable options.

stephena 5719fa117a - Added Stelladaptor support for joysticks and paddles. Since I don't
yet have a driving controller, I can't add support for it (donations would
be welcome :)

 - The buttons/axis events seem to work, but I really have to push
hard on the sticks for an event to register.  It's probably because of
the crappy controllers I have.  I'll test on a real 2600 when I get a
chance.

stephena 861bf5a21a - Added preliminary support for Stelladaptors. The first detected
Stelladaptor will act as the left joystick/paddles 0 and 1/left driving
controller.  The second detected Stelladaptor will act as the right
joystick/paddles 2 and 3/right driving controller.  Any other Stelladaptor
will be ignored.

 - Of course, since I don't actually have my Stelladaptor yet, only the
detection of Stelladaptors is present; the actual functioning is not done
yet (but I expect it will be quite easy to add it).

stephena ada3f7cf24 - Removed the 'joyleft' and 'joyright' arguments, since they never
really worked right anyway.

 - Stella now tries to open all joysticks you have (up to 4), and
they can then be remapped any way you want.

 - As of the previous cvs commit, all old state files are now
invalid.  Sorry, but it had to happen sometime (and it may happen
again).

stephena 6c3b06d19e - Added support for digital sound again. It didn't work as well as I
would have liked in the 1.3 release, and it still doesn't.  The background
music in Pitfall2 is there, but it's scratchy.  And in Quadrun, you only
hear one 'quadrun' instead of 'quadrun, quadrun, quadrun'.

 - For now, you can disable/enable it by (un)-commenting the line
'#define DIGITAL_SOUND' near the top of the SoundSDL.cxx file.

 - For those of you that care, here's the problem:
     Previously, the correct number of sound samples were created and
     the audio system had delays inserted to account for it.  Problem was,
     the delays were causing 'jumps' in the video rendering, since the
     sound code was delaying every frame.

     Now, the audio system only takes as many samples as is needed.  This
     eliminates the audio/video sync problems, since there are no delays
     at all.  But the problem now is that if more samples are generated
     than the audio system requires, some are lost and/or overwritten.
     I do place them in a queue, but the samples are being generated faster
     than they're being removed.  So things don't sound quite right.

 - At least that's what I think.  We need some way to combine both approaches,
so that the audio system only gets as many samples as it needs, but in *those*
samples, all the sound information up to that point must be present.  I guess
the samples will have to be mixed, or something.

 - If anyone has ANY suggestions at all, they would be greatly appreciated.

 - And for anyone who doesn't have a clue what I'm talking about, let me
say I really &&%*(&* hate sound programming.

stephena fa5d1f97ac - When switching to fullscreen OpenGL mode, only use some predefined, common

windowed mode since it was getting on my nerves :)

2004-04-12 23:28:43 +00:00
stephena 1f45ed9744 - Major changes across the board with respect to sound. The sound code
has basically been reverted to 1.2 functionality.  The good news is that
the video and audio are always in sync, even in Windows.  The bad news
is that we've lost advanced sound in Pitfall2.  I know what's required to
fix it, but I'm seriously considering doing a new release and waiting
until the release after that to fix it.  Right now (with release 1.3),
most games have laggy sound, even under Linux, but the background music
in Pitfall2 is there.  I'd rather do a new release with Pitfall2 not
completely working, but having everything else working great, than wait
another month or two.  I'm sure most people will agree ...

 - The Windows port has some slight popping every now and then.  Damn, I
really hate Windows sound programming.  It just can't handle low-latency
sound generation as well as Linux (shameless plug).

 - Added options '-fragsize' and '-bufsize', which set the sound fragment
and buffer sizes, respectively.  They're currently set to 512 and 1536,
and this seems to work best.

 - Fixed an error in calling 'putenv' in mainSDL.  Now the Windows port
actually starts with the game window centered.

 - Finally, IMHO (baring Pitfall2) Stella now works better wrt A/V sync
on Linux than z26 does on Windows (a bit of friendly competition :)

stephena 7c5ebdddf3 - Added an option to the makefile to specify the number of CPU's to use
with 'make -jN' when compiling on SMP or distcc-based machines.  Defaults
to 1 CPU, and most people won't need to touch it.

 - Cleaned up some sound related build options in the makefile.  Now
there is only one sound option (SDL, since the codebase is standardizing
on SDL), and the OSS and ALSA drivers are being discontinued.

 - Moved the settings that were specific to Linux SDL port to the emucore
Settings class, since they are now relevant to all SDL ports (including
Windows).

 - Reworked the sound selection code in mainSDL.  Now the '-sound'
commandline and ini-file argument is a boolean, representing whether
sound is enabled or disabled.

stephena b6325d98a0 I've finally started development on Stella again ...
Many changes to the makefile representing the 'SDL-ification' of the
Stella codebase.  Now there are 4 make options which should be
self-explanatory: "linux, linux-gl, win32, win32-gl".

The codebase now compiles under Linux (with gcc) and Windows (with MinGW)
from the same makefile without any editing or modifications.  So there
is finally full cross-platform support.

Next step is to fix the small OpenGL regressions in Windows, and finally
move to the dreaded sound code.  Then a new release ...

stephena eddc10294d All changes are to the SDL version.
Made emulator pause when toggling between windowed and fullscreen
modes.

Added code for the TEXTURES_ARE_LOST definition.  In Windows, when
changing the window size or toggling fullscreen/windowed modes, the
OpenGL textures are lost and must be reloaded.  This now works.

Fixed a long-standing bug in snapshot files.  I made sure they were
opened in binary mode.  That wasn't required in Linux.  Sometimes
developing multi-platform code can really work the bugs out.

stephena 1457853110 Some more cleanups wrt the sharing of the SDL codebase between
Linux and Windows.

Reworked the Makefile (again).  Now you have to edit it and select
which system you are using for the SDL port (linux or windows),
then start compilation with 'make sdl'.

The makefile is starting to get harder to manage, and with the
explosion of features, I'm looking into moving to a configure
script (autoconf and automake) for a future release.

stephena 41556196e4 Finally added the required modifications to the SDL port for
compilation in Windows.  There's still some work to do in the

Windows ...

I use the MingW32 environment with the Ming SDL libs from libsdl,org.

stephena 083245cf9c Added the ability to dynamically switch which palette the emulator
uses to the SDL port.  Currently, the three choices are the current
Stella palette (standard), the palette from version 1.1 (original),
and the one from the z26 emulator (z26).

The '-palette <standard|original|z26>' option can be used from the
commandline, and Control-P can be used while within the emulator.

I haven't actually added the z26 palette yet, so when you switch to
that one, you get a blank screen.

version to Windows (which already runs quite well).

This may eventually be a replacement for Cyberstella ...

stephena 8915cf50bf Added an in-game key 'Alf-f' to dynamically switch between filtering
modes in the OpenGL SDL port.

Updated the documentation with the changes to the SDL commandline
arguments.  Rewrote the Linux requirements and installation
procedures.

Merged all todo stuff into the Todo.txt file, and removed the
redundant CyberstellaTodo.txt.

stephena 4e8e332370 Completely (hopefully) removed all references to the registry stuff.
All Settings should now be saved in the stellarc file.

Activated all former settings in StellaConfig.  You can now select
different options from the config dialog box and actually have
them work in the emulation core.

Cleaned up the main file lister user interface a little.  Specifically,
when you resize the window, the internal file lister should resize
as well.  This one was bugging me for a long time.  There's still
some work to do when making the outer window smaller than the inner
one though.

Made first pass at the SoundWin32 code.  It now sounds *much* better
than it did before, but there's still some work left to do.  I've been
looking at other Windows Atari 2600 emulators (PCAE and Z26), and
I've noticed that while their sound generation is clear and doesn't
have pops, the pitch and latency is still off a bit.  The only time
I've ever heard it work correctly is in the Linux version of Stella,
and I'm trying hard to make Cyberstella work the same way.

Note, this isn't a slam again PCAE or Z26, or saying that Linux
is superior to Windows (I'll leave that to another discussion ;).
It's just that Stella and the sound code were originally
developed under Linux, and that's where it seems to work best
(and I'm hoping this will change).

stephena 120dd7b268 Re-enabled saving of the event remappings to the rc-file.
Moved the refresh() method to FrameBuffer::refresh(), since
all ports may need it.

stephena 6aef328c60 Removed most of the Registry stuff and replaced it with
references to SettingsWin32.

Made many changes to FrameBufferWin32, cleaned up the code
and renamed variables.  I may only release fullscreen mode
for version 1.4, so I decided to clean it up a bit.

Enabled SettingsWin32 code.  Now you can save/load state
files.

Reorganized the base Settings class a bit.  It had a
dependency on a Console being created when it shouldn't
have.  As a result, any changes made to event remappings
won't be saved.  I'll fix it tomorrow; time for sleep ...

stephena 0058d868a4 Made the lines on the menu boxes look a little better in the SDL
OpenGL port.

Added a FrameBufferSDL::refresh() method that's triggered when
the window needs to be redrawn (SDL_VIDEOEXPOSE event).
