Under Windows, it didn't matter, since createTextures() was called every
time createScreen() was. Under Linux, createTextures() is only ever
called once. Hence, the screen is never cleared.

Still to do is scale the OpenGL text to the current screen size. Right now,
it still shows up very small (and not centered). Also, fullscreen OpenGL
snapshots aren't quite working right yet. Both of these are easy to fix.

Mediasource.
Removed all snapshot-related code from the Console, since it didn't
really belong there. A static snapshot object is now created each
time a snapshot is done (in the EventHandler).
These changes should make it easier for those ports (like MacOSX) that
have native PNG-saving support to not use *any* of the snapshot code
at all.

the weird sounds that sometimes happened when a new state was loaded
(sound from the previous state was still playing).
Removed the '-paddle real' option from the description in the UNIX

and has been obsoleted by the Stelladaptor support.

It seems that sometimes switching to fullscreen in Windows in software

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.

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.

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.

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.

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.

any files.

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.

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).

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).

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.

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 :)

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.

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 ...
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@230 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

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.

compilation in Windows. There's still some work to do in the
SettingsWin32 class, and tweaking of the sound, but it's pretty
close. I think its the best that Stella has ever sounded on
Windows ...
I use the MingW32 environment with the Ming SDL libs from libsdl,org.
