stephena 48beb4fd1f First pass at automating the Windows builds as much as possible. Ideally, I'd like to just double-click a BAT file, enter some version info, and have it do 32 and 64 bit builds.
Updated the documentation for build info for Windows.  Still TODO is add more detailed info for Linux and OSX.

stephena 42f3052fbf Added TIA support for a '7-color' register model. This means we can see
all graphical objects in different colors in fixed debug colors mode,
even those that normally share a color register (ie, P0/M0, P1/M1, etc).

Removed TIA::updateFrameScanline, an unwieldy 600+ line function.  It
was useful as an optimization measure when Stella was first written,
but at this point I think it's more trouble than it's worth.  Removing
the code not only makes the TIA class much smaller and easier to
understand, it also fixes some graphical bugs in fixed debug colors
mode (bugs that probably wouldn't have been found otherwise).  Next on
the chopping block are the various 'masks', or at least the alignments
(which cause the arrays to be 4 times larger than they need to be).

stephena ea0e137a27 Modified TIA overscan code to only blank the screen when overscan turns to

way more accurately emulates what happens on a real system.

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 33130a78f0 Updated 'Fixed Debug Colors' for PAL mode to more closely match the ones
in NTSC.

First pass at disassembly of ZP RAM in the debugger UI.  For now, the
entire range is disassembled, with no regard for alignment (so the PC
won't necessarily always line up with the disassembly).  Also, changes
to RAM don't yet trigger a re-disassembly.

stephena 8f8095073b Better emulation of the starfield effect in Cosmic Ark and Stay Frosty.
The movement was already correct, but one of the missiles has weird
behaviour caused by 'confusing' the TIA.  This results in a four
colour-clock wide missile with the third pixel turned off.  I don't
know if this is entirely accurate, but I do know that the snow in
Stay Frosty now looks exactly the same in emulation as is does on a
real system, so I'm content to leave it for now.

stephena 67fec652b0 Updated TIA code to emulate the 'widening' part of the Cosmic Ark
starfield effect.  More research is required in this area.

Large update to exception handling throughout the codebase.  It seems
that in many cases, the correct 'catch' block was never being called.
I never see exceptions thrown very much, so that area doesn't get much
testing.  But I guess it's good that Stella doesn't generate many
exceptions :)

stephena 28f347cf86 It seems that in Windows, stringstreams must be initialized with data immediately after creation before they can be used. This really doesn't make sense to me, but at least it allows the rewind code to work. I hope this fixes similar issues in OSX.

stephena ef5c5de54f Fixed scanline => framerate calulation bug for those ROMs that generate
many more scanlines than a real TV would allow.  This fixes both graphical
corruption and slowdowns in Q-Bert ROM (which contains code to do a tight
loop extending VBLANK time, in effect generating a 'frame' with 1000's of
scanlines).

First pass at a method to determine the first 'relevant' scanline of
a TIA frame.  This isn't easy, because there are many conditions
for this to occur.  The eventual goal is to eliminate Display.YStart
tweaks in the properties file, and have the TIA code itself figure out
the best value.

stephena 000460306c Added "Fixed Debug Colors' mode, similar to the functionality in the
no$26K emulator.  Basically, when this is enabled, the COLUP0, COLUP1,
COLUPF and COLUBK registers are locked to hardcoded values.  This can
be used to clearly show which registers are drawing which part of the
TIA display.  For now, the colours are locked as they're shared on
a real system (so P0 and M0 are locked to the same colour).  Future
versions may separate these shared registers for even more clarity.
This functionality is toggled with the 'Alt-Comma' key combo.

Updated the state handler to reject loading state files older than
this version, since the TIA internals have changed.  This will be
done each time the TIA code changes from this point on.

2009-08-23 17:15:43 +00:00
stephena 3006419014 Scaled back some TIA changes from the previous alpha release. The changes
are too invasive to fix right now, and I haven't researched what the
correct route should be.  Basically, Stella doesn't properly emulate the
behaviour of writes to RESxx and NUSIZx while graphics are currently
being drawn.  The tweaks currently present restore functionality to the
2.8.4 release, but are still incorrect in some ROMs (Bumper Bash and Pole
Position).

Reworked 'object disable' mode in the TIA class.  It should now be
slightly faster, and correctly disable objects in all cases
(previously, it was possible for some objects to be enabled depending
on the state of other objects, even when they were specifically
disabled).

Changed NUSIZx descriptors in the debugger to more clearly indicate
what's going on.

Cleaned up TIATable enum's, and eliminated duplication enumerations in
different parts of the codebase.

stephena 35ad585c48 Modified -fullscreen commandline argument to accept an integer instead
of a boolean.  It now accepts value '-1' to mean 'completely disable
fullscreen mode switching'.  This was added because some systems with
buggy video drivers can't handle fullscreen mode, and accidentally
trying to do so can lock up such a system.

Fixed fullscreen/windowed switching wrt grabbing the mouse.  Sometimes
switching from fullscreen to windowed mode had the cursor trapped in
the window, even if grabmouse was disabled.

stephena 82268325a0 Added '-joyallow4' commandline argument and associate UI item in
InputDialog/Virtual Devs to allow all 4 directions to be pressed
simultaneously on a virtual joystick.  This support was always present
for 'Bumper Bash', but it can now be enabled/disabled for any ROM.
Note that the setting is ignored for 'Bumper Bash', as that ROM
requires it to be always turned on.

Fixed debugger rewind issue from last commit; the rewind list wasn't
being properly reset when entering the debugger or selecting a new ROM.

2009-08-05 20:33:40 +00:00
stephena 3c5cc40e08 OK, this looks like a huge update, but it's only because of some Serializer
class reworking.  Serializer class now handles read/write of state from
files as well as in-memory streams.  As a result, Deserializer class has
been removed.

Added state rewinding to the debugger.  For now, this is limited to 100
levels of undo, with a new state generated each time a step/trace/frame/
scanline advance is performed.  The undo level is 'rolling', in that it
remembers the last 100 levels (so you lose the oldest states when you
start adding more than 100).  For now, this is tied to the 'Alt-r' key
in the debugger.  Still TODO is add a button for it, and clean up some
TIA output issues when rewinding.

Added support for 6K version of Supercharger ROMs (this fixes issues
with the 6K version of Cubis).

Cleaned up the Serializable infrastructure, making sure that all
classes that need to implement it actually do so now.

Fixed issue with editable widgets in the UI, where pressing Enter
on the keypad wasn't actually being registered.

near the top of the list.  The TIA HMOVE stuff is well underway, the
Blargg NTSC emulation is being done by the Georgia Tech team, and the
debugger improvements (disassemble zero-page RAM, Distella integration,
and rewind in the debugger) will be started soon.

stephena 5e4b690d8d Well, it's finally here. First pass at the new TIA code, which improves
emulation when performing 'illegal' HMOVEs (aka, when modifying the HMxx
registers within 24 CPU cycles of HMOVE).

All tweaks for illegal HMOVEs have been removed; and all ROMs that
previously needed those tweaks are now working correctly.  Several other
ROMs are fixed as well, including Bumper Bash and Pole Position.

As this is WIP, there is also some breakage:

1)  Cosmic Ark 'TIA confusion mode' effects aren't complete; the
movement is correct, but the missile widths aren't corrected yet.

2)  Performing a write to NUSIZx while a player is still drawing
isn't complete.  This breaks several ROMs that worked before, such
as Galaxian and Space Instigators.

3)  Writes to RESPx aren't complete yet, especially if they're
combined with an immediate write to NUSIZx.

Most of the ideas (and some code) for these changes comes from
contributions to MESS and EMU7800.  Where applicable, permission
was obtained from the original author to use the code/ideas.

above 'YStart' scanline were not processed as all, as an optimization.
However, several ROMs can do collision detection above ystart, so
we now process the entire frame (but only display the stuff below ystart).

stephena 22544e1f00 The smallest addressable page size in Stella is currently 64 bytes,
so we need to make sure that Sub2K ROMs less than 64 bytes are
properly 'paged' to that size.

stephena 594954789c Surprise, surprise, Microsoft doesn't support the C99 standard,
and doesn't know what intxx_t datatypes are.  So we need yet another
check for Win32-specific stuff in BSPF.

Folded getTicks() from UNIX and OSX back into OSystem directly.
The default is now to use OSystem::getTicks() unless it's
overrided by a platform-specific OSystemXXX class.

stephena 8a8d04031a Converted OSystem::getTicks() to use 64-bit integers. This should fix the
problems with integer overflow, which could sometimes cause Stella to
sleep for long periods of time.  For those who are interested, the
problem was that SDL_GetTicks() wraps every 49 days (32-bit int
overflow), but since OSystem::getTicks() provides info in microseconds,
it multiplied the value by 1000.  This caused wraparound in 49/1000
days, or 70.56 minutes.  This almost exactly matches the reports on
AtariAge of 'lockups' occuring every 71 minutes or so.  It also
explains why attaching to Stella with GDB and bypassing the delay
allows the program to continue (as reported by another bugtester).

Added signature to detect UA bankswitching for Gingerbread Man ROM.

Bumped version number.
