stephena be2d42202e Fixed 'read from write port' bug in E7 bankswitching; while the read
from write port was correctly detected for the 1K area, it was actually
zeroing ROM instead of RAM!

Added support for 'read from write port' logic for the upper 256 byte
page in E7 bankswitching.

Bumped version # for release to testers on AtariAge.

stephena 6885416d02 Changed OSX preferences plist filename to net.sourceforce.Stella.plist,
in accordance with the naming scheme defined by Apple.  This means
upgrading to the next version of Stella will lose all settings for
OSX users (unless they manually rename their current plist file).

stephena ecb4689584 Some cleanups for the OSX port. Stella for the Mac is now known
simply as 'Stella', just as it is on other platforms (instead
of StellaOSX).  This indicates that the OSX port is now a
first-class citizen, with the same importance as Linux and Windows.
Also cleaned up various text files for spelling mistakes and
formatting issues in OSX.

Added credits for Richard Kennehan, who donated a 2600 console
and various controllers to help with Stella development.

stephena 48a48d8619 Added '-md5instate' commandline argument, which determines how a state load
is related to the currently running ROM.  If enabled (the default and current
behaviour), state files that do not match the currently loaded ROM will not
be loaded.  Otherwise, the state file will attempt to load.  Note that in the
latter case, this will probably cause 'bad things' to happen.  It's mostly
for developers who are constantly recompiling a ROM, and wish to use a
previously created state file even when the ROM MD5 changes.

stephena d8bca7a519 OK, this is the first pass at some love for the OSX port, which doesn't
get nearly enough attention.  This is about to change, since I'm moving
to using it full time at work (still Linux at home though!).

The 'Control' key modifier for OSX is now the actual Control key, just like
on every other platform (instead of Command).  The 'Alt' key modifier for
OSX is now the Command key (instead of Shift-Cmd).  Maybe in the past it
made sense for this, when keyboards weren't the same between platforms, but
that's no longer the case.  And since Stella requires at least OSX 10.4,
everyone using it from this point on probably has newer hardware.
Still TODO is consider a few special keys for OSX (minimize, hide, etc).

Updated documentation for new key combos, as well as the recent build
and debugger improvements.

stephena 4ac82ca56a Added separate build project for OSX Intel machines running Leopard (10.5)
or newer.  Obviously, this one only runs on x86 machines.  It's compiled
with the very latest compiler (Clang), which is much faster at compiling
as well as runtime.  And it also includes a 64-bit version, which is
only available on Snow Leopard.  The old build environment support 32-bit
in 10.4, 10.5 and 10.6 for PPC and Intel.

Fixed string overflow in reading settings from plist file in OSX.  I need
to figure out how to use C++ code from within Objective-C, since the
cause of the bug was C string code (which is notorious for buffer
overruns).

Bumped version # to test2, for some testers on AtariAge.

stephena 19f146038d Added more accurate functionality for the _rwport debugger command. It now
properly distinguishes between intermediate reads which are part of writes,
and ordinary reads.  In the former case, only a read which has a different
address than a write is flagged as an error; intermediate reads acting on
the same address as the corresponding write are considered normal, and won't
trigger a break.

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.

2009-11-08 18:42:12 +00:00
stephena 54a5d77542 Added '_rwport' debugger directive, which can be used in conditional
breaks to test whether an illegal read to the write port of cartridge
RAM has occurred.  It can be used as follows:

  breakif {_rwport == 100}   // break if read was done at wport address 100
  breakif {_rwport}  // break if read was done at *any* wport address

This currently works for all extended RAM carts that worked before.
Specifically, 4A50, DPC, AR and possibly several others aren't supported
yet.  More testing is required.

Renamed CartFASC and CartMB to CartFA and CartF0, respectively.  This
naming now matches that used in other emulators.

CartMC now properly handles read from write port, by using random
values instead of just zero.  However, no test ROMs are available for
this scheme, so there may still be issues.

2009-11-08 16:46:10 +00:00
stephena 3df721e0be Reworked 'read from write port' emulation for carts with extended RAM.
The values written and returned in such a case are now more accurate,
and are a combination of the previous databus value and randomization
(the latter emulating the randomness of Z-state bits).  This provides
more accurate emulation than before, where zeros were used instead.
In particular, types 3E and E7 are now working correctly for the first
time.  Thanks to Batari for suggestions in this area.

Moved random number generation from Cartridge to System class.

The Subversion build number is now shown in the AboutDialog box.
Still TODO is add architecture information (i386, x86_64, etc).

stephena 5ce401e6a4 Reorganized random number generation code in each Cart class. There
was duplicate code in many Cart classes and in M6532 class, and since all
these classes are subclasses of Device, it made sense to move the
functionality there instead.

Carts 3E and E7 now return a random value when attempting to read from
the write port.  Still TODO is determine what happens to the value at
that address (is it randomized or zeroed?).  Thanks to Batari for
suggestions and sample code.

Fixed bug in E7 carts when entering the debugger; bankswitch was being
inadvertantly triggered which caused emulation to fail.

Overall, I need to figure out exactly what happens when reading from
the write port for all carts with extended RAM.  There are two things
to consider: what value is written to the address, and what value
is returned.

stephena 2fa8b1ee70 Added ability to dynamically toggle TIA collisions for the 6 graphical
objects.  These actions are tied to the same keys as for toggling the
objects themselves, with the addition of the 'Shift' key.  For example,
toggling the P0 object is 'Alt z', and toggling P0 collisions is
'Shift-Alt z'.  Note that disabling an object will obviously disable
its collisions as well.  Still TODO is work out how these keys map on
OSX; the Shift key is already being used for something else.

Reverted Cosmic Ark 'starfield effect' to match the descriptions
given in the 'Stella 3.0 released' thread on AtariAge.  It seems the
system I tested this on has an Svideo mod board that changes the
output from a normal console.

Bumped state file format header, since the TIA internals have changed

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 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.
