with all related event recording/loading stuff, since it really didn't
belong in either the EventHandler or Event classes. Loading a previously
saved eventstream now loads the ROM state as well. All that's left to
do (for basic functionality) is for the EventHandler to poll the
EventStreamer for events, and then pass them directly to the Event class.
Still TODO is decide on a GUI for all this, and what it means to 'interrupt'
an eventstream (should we just stop the load, delay processing of it,
lock out all user input until the stream is finished, etc).

the first event seen is now used. So that means once 'Map' is pressed
in the EventMapper, you can no longer move the cursor using the joystick
axis; that axis event will be remapped to whatever action your remapping.
Disabled double-clicking in EventMapper activating remap mode, since it
causes problems when using joystick buttons as mouse clicks.

(where it really belongs). So the GUI is fully navigable using the joystick.
Joystick axes emulate mouse movement, and joystick buttons emulate a left
mouse click.

or continue running (when in ROM launcher mode) when attempting to use an
undefined cartridge type.

TabWidget. The fix is not as clean as I'd like, since it basically
checks for a certain case only (a hack). The TabWidget really does
cause a lot of problems, but for now I just work around it.

erase that axis from the analog assignment (if it was also assigned to
an analog event).
Started work on intelligent focusing in the InputTextDialog, but it
requires some more work on the focusing the Dialog class (which is really
sort of a mess).

in GUI menu mode. The code was too troublesome to fix, and navigating
a GUI with a joystick simulating a mouse is a broken concept anyway.
In place of joy-is-mouse navigation, added the ability to use the cursor
keys or joysticks axes to 'tab' between different focused objects in
GUI mode. This is much more intuitive, and is how navigation works in
a mouse-less, game console based system. Also, any joystick button (or
enter/space keys) activate the currently focused item.
For now, only the CommandDialog can be accessed this way. It really
only makes sense here anyway, since many GUI objects in the other menus
really need access to a keyboard and mouse, and if you have those, one
can already navigate the menu.
Overall, this should make arcade cabinet style access much easier. One
can map the CommandDialog to a joystick button, navigate with the joystick
axes, and select an item with any joystick button. So Stella can be
started, play a game, and then exit, all by just using the joystick. It
also solves quite a few usability problems for the WinCE and PSP ports.

are stripped, since they have special meaning in the cheat file.
Added support for one-shot cheats. Basically these work exactly the same
way as normal cheats, but they are only evaluated once, and are never
saved.
Cleaned up the IFDEF mess for FrameBuffer and Sound objects in OSystem class
by creating a MediaFactory class that deals with it. This might seem like
just moving the problem elsewhere, but it does help remove the clutter in
OSystem, and make compiling slightly faster whenever the FrameBuffer classes
are changed. No porter should ever have to touch the emulation core classes.

we can also remove RTTI support. This may result in a slightly smaller
binary.

After this, hopefully state (and eventstream) files will be portable
between different platforms, even those differing in endian-ness and
bit length. Ints are now stored and retrieved in little endian format
and are 4 bytes long. So state files should still work on 32-bit x86 Linux,
but old state files will no longer be valid for 64-bit or non-x86 systems.

from 0 to 100 percent, and represent minimum (0) to maximum (100) speed.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@910 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
TODO is add a scale factor (for each paddle) to the GUI, so one can
adjust the speed/amount of movement.

Pressing 'Ctrl e' now starts/stops event recording (key is temporary and
will probably change). An state file is then generated containing the
state when recording started, and the eventstream up to the point when
recording stopped.
Next I'll work on loading the event state file and replaying the events.
This one is a little harder, since it has to override EventHandler::poll()
and use events from the eventstream. Hopefully rudimentary support will
be there by the end of the weekend.

many places other than the GUI code.
As a diversion from the joystick stuff, I'm experimenting with event
recording. Eventually, this will allow one to record a state + events,
and then load that INP file again. When loaded, Stella will replay the
events, and you'll be able to see exactly what happened before. Since
this is based on frames, the replaying can speed up and slow
down by changing the emulation framerate. And it can be exited at any
point, and normal emulation can continue. Or at least that's how I
want it to work.
A preliminary spec for the event stream is -X A B A B ... -X ...,
where X represents how many frames to wait, and 'A B' are event/value
pairs representing an event in Stella. I think this is very similar
to the scheme that Thomas J. recently added to z26, so converting to
a Stella eventstream should be easy.

simulated paddles for now. I got it working, but I'm not sure how
useful it will be. Maybe it's better to just add joystick emulation
for paddle events, and not care whether the axis are digital or analog
(it would certainly be easier code-wise), using something like JoyMouse??
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@904 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
an axis is analog or digital (but this may prove to be insufficient).
This will be useful for the paddle emulation code. If a paddle event
is detected *and* the axis is analog, then the eventhandler will generate
true analog values, which are more accurate than digital. Otherwise,
paddle events associated with a digital axis will have the analog values
emulated by use of a JoyMouse-type structure.
Eventually, this code can be extended to deal with other analog-type events
(lightgun, etc) or other analog axis (trackballs).

complete, since I can play a two player game of River Raid with one
gamepad (P1 using D-pad and button 0, P2 using analog stick and
button 1). Still TODO is add support for remapping paddles, but
this will be quite easy. After that, maybe the ability to use
keys for paddle movement. This one is a bit harder, so I may leave
it for a future release.

be supported. Currently, axis handling is completely broken.

cheats don't contain characters that are reserved for the cheat file
(comma, colon, quote, etc).

works correctly, and inserts the cheats for whatever ROM happens to be
loaded.
The CheatCodeDialog now communicates with CheatManager, meaning that
cheats can be seen in the dialog, and enabled/disabled with their
respective checkboxes. Still TODO is add support for adding/removing/
deleting cheats, and for one-shot cheats.

and a comma-separated list of cheats. Each cheat is specified as a
colon-separated string, defined as "NAME:CODE:ENABLE".

where each cheat can be toggled on or off. Of course, it doesn't
actually do anything yet, since it isn't connected to the
CheatManager. For now, input of cheats from the GUI is completely
disabled. Commandline should still work, though.

instead of being possibly 'massaged' by EventHandler::handleEvent().
This should result in slightly faster operation, and also allow
more accurate emulation of the Stelladaptor joysticks (ie, pressing down
hard on a joystick and activating all four directions will do exactly
what a real 2600 would do).

switch/case, hopefully making things faster.
Fixed bug while in pause mode and commands still being processed when
they shouldn't be.
Fixed annoying long-standing bug with the emulation core receiving
both joystick left/right and/or up/down events at the same time.
This results in lockups in Astroblast, and 'losing' the gun in Berserk.
A real 2600 doesn't allow this, so we shouldn't emulate it either.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@886 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
made no sense to restrict Stella to only work with two joysticks, since
there's no reason one couldn't use four devices, with each one emulating
a paddle (once I get paddle remapping done). So I've removed that
restriction, and also removed the 'leftport' and 'rightport' arguments.
The one case where remapping a joystick *does* make sense is for
multiple Stelladaptors. In that case, there might only be one
Stelladaptor installed, but you'd like it to emulate the right virtual
port. Previously this wasn't possible, but now it is with the addition
of the 'sa1' and 'sa2' commandline arguments. These arguments accept
either 'left' or 'right', specifying which virtual port to emulate.
Updated the InputDialog virtual device tab for remapping Stelladaptors.
Shortened some keynames in EventHandler, so that the actual character is
used (for example, ? instead of QUESTION).
Some fixes for the OS/2 port.
