Stella 6.4 released

02 Nov 13:20
Choose a tag to compare

Time for a new release of Stella. This one included quite a few new features over 6.3, so we decided to bump the version number more quickly than usual. Changelog as follows:

  • Added basic (entire and single line only) text cut/copy and paste.

  • Added color parameters to 'Custom' palette.

  • Some improvements to AtariVox-USB adaptor functionality:

    • Made serial port used for an AtariVox-USB adaptor editable.
    • Autodetection of serial ports no longer messes up devices plugged into other serial ports.
  • Added CPU load stats to debugger. Related to this, added debugger pseudo-registers '_ftimreadcycles' and '_fwsynccycles' to show the number of cycles since the start of frame under certain circumstances (see manual for more details).

  • Fixed bug with aspect correction and fullscreen mode; snapshots from such a mode are now pixel-exact.

  • Fixed a bug that caused CDF ROMs to crash on the Retron77 and reduced ARM emulation performance for CDF ROMs on other platforms.

  • Fixed crash with missing or incorrectly sized SaveKey data file, and with certain functions not working (erase pages, erase entire EEPROM).

  • Fixed Atari mouse autodetection.

  • Fixed bug in ROM launcher, with last ROM selected not being remembered when exiting and re-entering a directory.

Stella 6.3 released

07 Oct 11:20
Choose a tag to compare

Time for a new release of Stella. Changelog as follows:

  • Added adjustable autofire.

  • Added 'Dark' UI theme.

  • Extended global hotkeys for debug options.

  • Added option to playback a game using the Time Machine.

  • Allow taking snapshots from within the Time Machine dialog.

  • Added the ability to access most files that Stella uses from within a ZIP file. This includes the following:

    • Per-ROM properties file (so one can distribute a ROM and its associated properties).
    • Debugger symbol (.sym) and list (.lst) files, etc.
    • Several others, as we extend the support.
      Basically, you are now able to put many files that Stella uses inside one ZIP file, and distribute just that file.
  • Extended AtariVox support to handle flow control, so that long phrases are no longer corrupted/cut off. This includes properly supporting the 2600-daptor II, which is flashable to an AVox-USB converter.

  • Added auto-detection of the serial port used for an AtariVox-USB adaptor.

  • Added QuadTari controller support.

  • Added option to select the audio device.

  • Added support for CDFJ+ bankswitching type.

  • Further enhanced UA bankswitching to support more Brazilian carts.

  • Added option to display detected settings info when a ROM is loaded.

  • Added another oddball TIA glitch option for delayed background color.

  • Added option to disable aspect ratio correct scaling.

  • Added debugger pseudo-registers '_timwrapread' and '_timwrapwrite', which are set when the RIOT timer is read/written on timer wraparound, respectively.

  • Bankswitching schemes BUS, DPC+ and CDFx now work when startup bank randomization is enabled (these schemes now ignore that setting).

  • Replaced "Re-disassemble" with "Disassemble @ current line" in debugger.

  • Fixed bug when taking fullscreen snapshots; the dimensions were sometimes cut off.

Stella 6.2.1 released

20 Jun 19:00

A quick bugfix release for 6.2. Changelog as follows:

  • Fixed Pitfall II ROM not working correctly.

  • Fixed crashes when using some combinations of bankswitching schemes on incorrect ROMs, or when using invalid ROM file sizes, etc.

  • Fixed RIOT timer behaviour on reading/writing at the wraparound cycle.

  • Fixed incorrectly setting D6 bit on TIA reads in some cases. Related to this, improve 'tiadriven' option to randomize only D5..D0 bits.

  • Fixed custom palette and TV effects adjustable slider rounding issue.

  • Fixed some bugs in 3E+ scheme when using non-standard ROM sizes.

  • Fixed crash in Audio & Video dialog when opened from debugger, and the debugger window sometimes being resized when using the Options dialog.

  • Make NTSC custom phase shift not affect Yellow anymore.

  • Fixed '1x' snapshot mode; TV effects are now disabled. This mode now generates a clean, pixel-exact image.

  • Fixed mappings sometimes not being saved in the Retron77 port.

  • A ROM properties file may now be placed next to the ROM (with the same name as the ROM, except ending in .pro), and Stella will automatically apply the properties to the ROM. [NOTE: this was present in 6.2, but was mistakenly left out of the changelog]

  • Added button to Game Info dialog to save properties of the currently loaded ROM to a separate properties file (in the default save directory). This is useful in conjunction with the previous item.

  • Allow changing custom palette and TV effects adjustables in 1% steps again.

  • The codebase now compiles under gcc6 again. Future versions will require gcc7, though.
