stephena 9137b93c80 Some more code pruning. Basically, all classname references to OpenGL
have been changed to 'SDL2'.  From this point on, the OpenGL-specific
code will be removed, and replaced by SDL2-specific hardware-accelerated
code.

Cleaned up (mostly) the API of FrameBuffer vs FrameBufferSDL2.  Since the
FrameBuffer class is an emucore object, it should have no knowledge of SDL,
or any particular rendering toolkit for that matter (just in case we want
to move to SDL3 eventually :) ).

At this point, all checks for OpenGL have been removed, so if you don't
have it on your system, Stella will fail to compile and/or run.

stephena f4d0641219 A rather large commit, but basically all that's happened is
converting StringMap to VariantList.  In the process, some of the
code is much cleaner, and the Variant infrastructure allows
work to continue on a more full-featured ContextMenu.

stephena ac1bccf454 First pass at adding a cart-specific bankswitch/info tab to the
debugger.  In the process, I had to spend several days extending
the UI/dialog class to actually contain multiple tabs.  This was
harder than expected, and it still isn't quite finished.  In many
ways, we're beginning to reach the limits of the current code; it
was never designed for a full-fledged, graphically rich UI.

For now the tab is empty, but eventually it will contain general
info about the ROM bankswitch type (size, virtual layout, etc),
but also cart-specific info, including the ability to change
banks, which can be vary greatly among the different schemes.
Eventually, it may even allow to see/modify very cart-specific
info (like display RAM in DPC, etc).

Better handle errors in opening the serial port (AtariVox support)
for Windows and OSX.

stephena 4750c64a17 Phosphor mode now works with Blargg TV effects! It takes an extra 2-3 MB
RAM to do so, which I agonized over for about a week, but I feel it's
a fairly good tradeoff for the features we get.  Eventually, I may come
up with a more accurate phosphor mode which eliminates this approach
entirely.

Reverted OpenGL framebuffer to 32-bit colour mode.  We're using Blargg
effects, so we may as well get the full fidelity out of it.  Besides,
testing has shown that there's not much speed difference between 16
and 32 bit modes, making me think that 16-bit is probably be swizzled
to 32-bit anyway.

Bumped release date to June 1, version to rc1.

stephena e7b38e9963 Custom TV 'adjustables' can now be changed dynamically as follows:
- Alt-9 / Shift-Alt-9 selects (increases/decreases) between
    the various adjustables
  - Alt-0 / Shift-Alt-0 increases/decreases the actual values for
    the previously selected adjustable

Cleaned up the API a little, moving some stuff from Console to
FrameBuffer class.  I think we're due for a pretty major
reorganization of parts of the codebase very soon.

stephena e3fa8da1f9 OK, Blargg is now officially in the codebase! There's still quite a bit
left to do, but the basic functionality is now there.  Alt 1 - Alt 6
selects among TV modes as follows: off, composite, svideo, rgb, bad and
custom.  The latter is just composite at this point; there's no code to
actually change specific adjustables yet.  Alt 7/Shift-Alt 7 increases/
decreases scanline blend intensity (20% - 100%).

stephena 186fa5c1be Before I get back to mousemode and Blargg stuff, I decided to
make another pass at getting rid of raw pointers.  As I've come
to realize over the years (and in particular with reading the C++11
standard), raw pointers are evil and error-prone.  So this fixes
some of them at least.

stephena c95d5f804d Updated all files to copyright 2012. Happy New Year to anyone reading
these logs!

Moved TODO and Credits info directly to the webpage, where it will hopefully
be easier to maintain.

Fixed 'crackling' sound when loading a new ROM, introduced with the 3.5
sound restructuring.  It looks like stale data was being loaded by the
sound processing callback.  As well, moved the computation of certain
division variables from the sound callback to the framerate re-calculator
(where it's recomputed 1/5 of the time or less).

Updated AboutDialog with info about Stella DonationWare status, and active
members of Stella development.

Updated OSX in-app HTML documentation about Stella DonationWare status.

Bumped version # to 3.5.1_svn, and the process starts again.

stephena a7710ab1af Clean up some references to OpenGL buffer type, which actually
mean 'hardware-accelerated, double-buffered'.  This distinction
is important, since eventually such a mode won't necessarily be
OpenGL-backed (it might be Direct3D, OpenGLES, etc).

stephena c2992f5097 Large reorganization of the OpenGL code, separating out FBSurfaces into
distinct GUI vs non-GUI (aka TIA) classes.  This makes it easy to proceed
from this point on, since I don't have to worry about breaking one mode
when making changes to the other.

Preliminary support for TIA scanlines in OpenGL mode.  It's disabled for
now, but is progressing nicely.  This will be part of the new TV effects
in the next major release.

when changing between video modes).  Added extra signature to the

stephena 4e6d4cb1c6 Cleaned up some inlines that weren't needed.
Updated documentation with info about 2600-daptor, including
usage and its creator.  Also included more in-depth explanation
for the various controller types.

Errors from the Thumb ARM emulation code are now caught as exceptions,
and thrown to the parent class instead of calling exit() and simply
crashing Stella.  For now, the messages are simply printed and
emulation continues.  This will be expanded to show a detailed crash
log in the debugger, and offer the option to exit the ROM.

Removed most of the menus from the OSX port.  They weren't being
maintained anyway, and most of them didn't work.  I've modelled this
on the way other cross-platform OSX programs work (notably, ScummVM).
Basically, there are menus for exit and help, but otherwise you
should use the menuing system in the application itself.

stephena 264145a939 Huge improvements to paddle and mouse handling:
- mouse can now emulate joystick, booster-grip and driving controllers
 - digital and mouse sensitivity for paddles can now be tweaked
   separately, and have a greater range
 - the mouse now correctly honours its controller setting, and only
   controls a device on one one port (not both at the same time)

Added support for 2600-daptor device.  Credit for creator of device
is forthcoming.  This device is basically an updated Stelladaptor,
with improved handling for paddle data.

Grabmouse functionality is no longer user-definable; the mouse is
always grabbed while playing a game, and released otherwise.

stephena b756f8c14a Fixed several errors/crashes when attempting to open a window larger than
the given screen.  This is allowed in windowed mode, since the window
manager normally takes care of it.  In the case of fullscreen mode, however,
it is never allowed, and an error message is shown.

stephena 7411867290 Decided to take a little break from the debugger stuff, and clean up
the various header files.  Basically, I'm following advice from
Effective C++, and including only what's absolutely necessary.  For
definitions that don't need to be included, the designation 'class xxx'
is used instead.  This could potentially lead to faster compile times.

stephena f3483ca8b1 When in 'small' window mode and attempting to open PAL ROMs larger than the
screen size (vertically), the window will open in partially truncated mode,
where the top of the PAL image is cut off.  This normally won't be a problem,
as it's mostly blank space anyway.

App window centering is now honoured when changing video zoom levels, not
just when changing eventhandler states.

Bumped version # for another test release.

stephena 6faa9b4b69 Several fixes across the board for better functionality in 'small'
window mode.  Using modes smaller that 640x480 should now work in
all cases when using the 'maxres' commandline argument.  Also, the
lower limit of 320x240 is now strictly enforced in all cases.

stephena d0391c28f2 Added 'continuous snapshot mode', currently tied to the Shift-F12
key.  This enables automatically taking snapshots every X seconds
while in emulation mode.  The interval (in seconds) can be set
with the 'ssdelay' commandline argument.

Some minor cleanups to the EventHandler methods, making them
const when possible.

Added latest DPC+ changes from Spiceware.

Fixed issue with ROMs that run entirely from ZP RAM; no disassembly
was being generated when entering the debugger.  For now, this
special case is detected, and the disassembly is generated for
the code that ran before the PC entered ZP RAM space.  Eventually,
this will go away when the Distella fully supports disassembling
below 0x1000.

above and beyond 'the Stella Team'.

stephena c12a2e6043 Checks are now performed when attempting to open a window smaller than
320x240 (the minimum that Stella supports).  On 'small' systems using
1x video mode, this means most NTSC games will open in a window of size
of 320x240, even though the native size is normally 320x210 (or so).
In these cases, the image will be centered vertically.

Added FrameBuffer::invalidate(), used to signal that the complete
framebuffer can be trashed and entirely written over.  This is only
active in software mode for now, where it fixes 'overdraw' problems
with 320x240 dialogs drawn underneath 320x210 TIA images.

stephena 00f8ffb686 Revamped the result on floating pins for TIA reads. Previously, this was
controlled by 'tiafloat', which has now been removed.  Now, all
undriven pins take on the last value on the databus.  This fixes a bug
in those reads where bit 6 or bits 6 & 7 are also undriven (previously,
these bits would always be zero, and only bits 0-5 were from lastdatabus.

Added new commandline argument 'tiadriven', which defaults to false.
In this default case, relevant bits take on values from the databus.
If true, relevant bits still take on databus values, but some are
randomly driven high as well.  This helps to expose bugs when
developers assume the values for undriven/floating bits.

Added 'uimessages' commandline argument and associated UI item.  When
disabled, messages which are normally shown in-game are disabled.
Certain messages which indicate a serious error are still shown, however.

stephena a7da944b36 Simplified TIA class by removing 'greying' functionality to the debugger,
where it more properly belongs.  The greyed values are now from PAL
color-loss, which is also calculated for NTSC (though it's never actually
used in NTSC mode for regular rendering).  This also fixes problems with
debugger state files being saved with greyed values, and sometimes having
the frame greyed twice (hence making it impossible to see).  It should
also result in a slight speed increase, since some code has been taken
out of the TIA rendering fast path.

Added electron beam indicator the the TIA output in the debugger.
Basically, it's just a small square indicating where drawing will
start for the next instruction.

Fixed TIA output in the debugger so that right-clicking and selecting
'fill to scanline' actually works without first having to manually
enter partial frame mode.

stephena 2bc2ff639c Handle 'read from write port' functionality for CV carts. Still TODO are
the ones that bankswitch in RAM, since I don't know what should happen there.

Added 'exitlauncher' commandline argument, which specifies the functionality
of the 'Exit to launcher' action; should exiting a game actually go back to
the launcher, or exit the program entirely.  Also added a UI item in UIDialog
for this.

Reworked the fullscreen/windowed handling in FrameBuffer, simplifying the
logic for determining whether the SDL surface is actually in fullscreen
or not.

stephena 79e4e42ae7 OK, this is a BIG commit.
Added CRT simulation as described by Ian Bogost in the AtariAge thread
'CRT simulation for Stella.  This is just the first pass, but things
are working nicely so far (for those systems that can support it).  It
requires at least OpenGL 2.0 with GLSL (GL Shading language).  Added
the commandline arugments 'tv_tex', 'tv_bleed', 'tv_noise' and 'tv_phos'
used to set these various effects, as well as the ability to set them
within the Video Settings dialog.  More documentation is forthcoming
on this.

All bankswitch modes that use SC RAM now act correctly when reading
from the write port (the RAM is erased).

Patching ROMs with bankswitch type 0840, SB, UA and X07 is now working.

Went through all the bankswitch classes and converted multiplication/
division to shift operations whenever possible.  It's a
micro-optimization, but what the heck; every little bit of speed counts.
