2.0.1 to 2.1: (January 29, 2006)
* Added phosphor effect, similar to z26
. Useful on ROMs which alternate
sprites from one frame to another, resulting in an annoying flicker.
When using phosphor mode, a pixels colour is mixed with its previous value,
resulting in a blended image that doesn´t flicker, emulating the
phosphoresence effect on a real television.
* Added ´pp´ developer commandline argument to set the "Display.Phosphor"
property, and ´ppblend´ to set the amount to blend pixels in phosphor
mode. Also added ´Alt p´ key to enable/disable phosphor effect while
ROM is emulated. By default, phosphor mode is only used when necessary,
as specified in the stella.pro file.
* Renamed ´cheetah´ commandline argument to ´cheat´.
* Added per-frame cheatcodes (4 characters long), which are evaluated
* Added cheatcode GUI
, where cheats can be named, edited, saved, etc.
* Cheat codes are now saved to stella.cht file and are automatically
reloaded when Stella
* Improved ´joymouse´ functionality. While in GUI
mode, any axis will
simulate mouse movement, and any button will simulate a mouse click.
So the GUI
can be completely navigated without a mouse.
* Improved CommandDialog and LauncherDialog wrt joymouse functionality.
These dialogs are used more than any other on devices without a mouse,
so joystick axis movement switches between GUI
objects, rather than
simulating the mouse. This leads to much faster selection of objects.
* Added mapping of multiple SDL
joystick axis to Event Mapping.
* Added joystick hat support, and mapping of multiple hats to Event Mapping.
* Added remapping of paddle emulation to the keyboard or joystick axis
(the mouse is still used by default for paddles). Related to this,
use more precise analog values when analog axis are mapped to
analog-type events (such as paddles).
* Treat joystick events as other types of controllers based on the virtual
port entry in stella.pro. This means that mappings for a joystick will
emulate other devices when necessary.
* Added ´sp´ developer commandline argument, which sets the
"Console.SwapPorts" property and swaps the arrangement of the virtual
ports. Useful for games like "Raiders of the Lost Ark", where the
joysticks are normally swapped.
* Added ability to set which Stelladaptor device emulates which virtual
joystick port (´sa1´ and ´sa2´ commandline arguments, which accept
´left´ or ´right´).
* Fixed issues with jittering joysticks/mice causing weird events when
* Added ´freq´, ´tiafreq´ and ´clipvol´ commandline arguments, which
affect the sound subsystem (see manual for further info).
* Made state files completely cross-platform, both in terms of endianness
as well as CPU size (32 vs. 64 bit).
* Fixed crash with using ´cheat´ and ´break´ from the commandline.
* Implemented dynamic loading of OpenGL
