Stella 2.4

Stella is a multi-platform Atari 2600 VCS emulator.
Stella was originally developed for Linux by Bradford W. Mott, however, since its original release several people have joined the development team to port Stella to other operating systems such as AcornOS, AmigaOS, DOS, FreeBSD, IRIX, Linux, OS/2, MacOS, Unix, and Windows. The development team is working hard to perfect the emulator and we hope you enjoy our effort.
On this site youll find information about downloading, installing, using, and enhancing Stella. Youll also find useful information about the Atari 2600 and emulation.
Enhancements:
Added new video sub-system where fullscreen and windowed modes are treated
differently. Windowed modes now use -zoom_tia and -zoom_ui arguments,
while fullscreen modes can be specified by resolution using the new
-fullres argument.
- Widescreen video modes are now supported; Stella will simply center the
image with surrounding black borders.
- Many UI-related changes, including resizable ROM launcher and debugger
windows, and a new UI palette (the previous classic palette is still
available). This is still a work in progress.
- The locations of all major config files (statedir, palette file,
cheat file, properties file, etc) are now configurable from the
commandline and within the UI.
- Updates to TIA palette support. Added SECAM support, and removed the
built-in original palette. Standard, z26, and user are still
available.
- Various bugfixes to some debugger commands. The run command no
longer causes a crash, and several others have better error-checking.
- Added more complete cartridge auto-detection for Commavid (CV), 3E,
3F and Activision (FE) formats.
- Removed XStart and Width ROM properties, since the forthcoming TIA
rework wont be using them.
- Reworked internal storage of ROM properties to be faster and take up
less space.
- Added several different ways of stretching the OpenGL image to the
-gl_fsmax argument, for more flexibility.
- Removed OpenGL aspect ratio setting favour of the previously mentioned
video changes. Well see how this goes.
- Removed dirty-rect support from software rendering, since it was actually
sub-optimal in Windows and OSX and defaulted to off in previous versions.
- Added support for gzipped ROMs.
- Re-added pause support.
- Re-added support for Windows 98.
- Removed support for STELLA_BASEDIR environment variable, since each
config file can be now configured separately.
- Removed -fastscbios argument, since it must always be turned on.
- Removed PSP support, since it hasnt been updated in over a year, and
someone else is maintaining another port elsewhere.
- For the Unix/Linux port; fixed make install issues, and changed icon to
PNG format.
