The
Stella Team has updated the Stella Atari 2600 emulator to version 2.7.7. The
Linux,
Mac OSX and
Windows ports are now posted. Other ports will be posted as they become available.
Here's what's new in Stella 2.7.7:
- Corrected emulation of CPU opcodes involving 'decimal' mode (ADC/RRA and SBC/ISB). Special thanks to SeaGtGruff and others on the Stella mailing list for in-depth discussion and creation of test ROMs.
- Fixed bug in F4SC bankswitching mode; writes to bankswitch addresses weren't triggering a bank switch.
- Changed internal sound frequency of Pitfall 2 from 15.75KHz to 20KHz, as this sounds much more authentic when compared to a real cartridge.
Alert readers will notice that we missed the boat on Stella 2.7.6. It was released on April 14th. We've been working on some major additions to the site and it just slipped by.
Here's what
was new in Stella 2.7.6:
- Added support for 'EF' bankswitching (Paul Slocum Homestar Runner), as well as auto-detection of this format.
- Added support for 'EFSC' bankswitching, as well as auto-detection of this format. This is similar to the 'EF' scheme, but also includes 128 bytes SuperChip RAM.
- Added autodetection for '0840' and 'SB' bankswitching formats.
- Improved autodetection for 'UA' bankswitching format.
- Fixed bug in selecting video modes larger than the current screen; the resulting video mode will now be the largest one available (previously it selected the smallest one available).
- The currently selected CPU register now displays its value in decimal and binary (in addition to hex) in the debugger.
Stella 2.7.7 is available on our
Stella page.
