Introduced 'launcherroms' argument, which specifies to show only ROMs or all files in the launcher.
This functionality is tied to a RMB context menu in the launcher; eventually we may add a checkbox to the UI for it.
Previously this was done by SDL_AddTimer, but the new approach is much better:
- it is proper C++ (using std::thread and lambdas)
- It is not tied to the SDL toolkit, which is C-based
Also, re-added logic to reset events ~0.5 seconds after starting ROM emulation; this resets 'hold' events
- Made BoosterGrip set defaults for analog pins, just like Genesis
- Removed superfluous call to update an unchangeable pin in Genesis
- Renamed Controller resistance constants to indicate that they are actually constants
- Changelog updated for recent fixed from Thomas J.
- Minor formatting fixes in TIASurface class
- Updated documentation for 'ss1x' mode; snapshots now have only scaling disabled, not effects removed
- Updated snapshots for change in ss1x, and also ran them all through pngcrush, to optimize size
- changed from templates back to inheritance (sorry DirtyHairy :))
- added 'tsense' commandline argument and associated UI
- updated docs and screenshots for new functionality
- An extraneous TAB key event was being generated
- This is possibly an SDL bug in Linux only; it doesn't happen on other systems
- I've contacted the SDL mailing list for more info, so this code may be temporary
until after an instruction was executed. Also, toggle-able widgets
(pixel and bits) in the debugger can now be toggled with a single
mouse click, not a double-click. These fix issue #15.
This is enabled in the UI or through the 'tv.phosphor' commandline
argument. Note that what was previously 'tv.phosphor' (for setting
the blend level) is now 'tv.phosblend'.
Updated documentation in various places.
Added new 'tv.phosphor' commandline argument to accomplish the above,
and associated UI item in Video Settings.
Updated docs for 'tv.phosphor' and 'tia.debugcolors'. More work is
needed on this, since I need to add screenshots for this new functionality.
the fixed debug colors to user-defined preferences. Note that there
are 6 registers (P0,M0,P1,M1,PF,BL), and the option takes a string
of 6 characters, where each represents a colour for the respective
positional register (ROYGBP are the choices).
I may add a UI item for this, but this is as far as I will go with
allowing user editing.
to work like the old 'm' versions, so they work on all mirrors and
also allow one to enter a range of values to trap. Added more
stringent error checking for parameters.
- 'cls' now only clears the screen, and not the command history
- 'help' accepts another command as an argument, to give more info
about the command (ie, help breakif is now valid)
- command completion now works on built-in functions and pseudo-ops
file. For most people, that means the files are now stored in
'~/.config/stella' instead of '~/.stella'. Manually moving the directory
will be necessary if you wish to keep the old settings.
that the register held values up to 255 (when it should only contain 0-159).
Thanks to Omegamatrix for the report and fix.
On another note, I hope to get back to Stella development soon; it's been a
rough time since the last release.

For now, only the Paddle class is modified. Still TODO is add the

Added shortcut key to toggle TV scanline jittering, and have it default
to off. I'd really like to enable it again eventually, or perhaps use some

number.name convention (which seem to be pass #'s for DASM). Initially
having this info in Stella was simply visually inconsistent, but now
it also interferes with recompiling when saving the disassembly (IOW,
the data put into the symbol file by DASM can't be fed back into DASM

Once a frame has started, it means a new frame should be added. This
fixes a bug in the debugger UI whereby the frame count showed the previous
value, since sometimes you could enter the debugger (with a cond BP)
before the end of the frame was technically reached.

bases into a Common::Base class. Previously, this functionality was
spread across several classes, and used different approaches to formatting.
While the code still mixes C++ streams and C-style sprintf's, at least
it will now be easier to modify it all in one place.
Related to the above, added ability to use upper or lower case
characters for HEX output in the debugger. This is toggled by the
new debugger prompt command 'uhex', which is also tied to a new
commandline argument, 'dbg.uhex'.

All DataGridWidgets (ie, most of the inputs in the debugger) have more
strict input filtering, allowing to use $,#,\ specifiers for different
bases, as well as restricting input based on the specifier used (ie, if
you've entered a '\', only '0' and '1' are allowed, etc).

account the more esoteric bank schemes. Currently, some functionality
is disabled/removed for now; I'll work on this for the next commit.
The format for displaying disassembler GFX/PGFX (binary or hex) is now
obeyed in the disassembly file output as well.
Changed various comments/enums/etc referring to 'preliminary' code to
'tentative' code, matching the actual intended meaning and the current
documentation.
Small API change for EditTextWidget; changed method name to setText, since
that's what I keep typing for some reason.

Fixed bug after pressing Enter/Return in EditTextWidgets; it was exiting
from edit mode, which locked out certain key handling (these widgets
are always editable, and should not be exited in such a way).
