VICE

3.9

** general
----------

- (mostly) rewritten joystick mapping and -input system. Both the SDL and GTK
  versions share common code now, have the same features, and can use the same
  mapping files. However, unfortunately we ran out of time and could not implement
  a related UI in the GTK port yet - which means you will have to create and/or
  install the required mapping file manually like this, if the (very simple)
  default mapping does not work for you:

  1) find a matching SDL mapping file in DATA/C64. If none of the existing ones
     matches your controller, you may create one yourself (either manually or
     using the SDL port). (*)
  2) rename the mapping file to "gtk3-joymap-<MACHINE>.vjm" - for example
     gtk3-joymap-C64SC.vjm
  3) copy the resulting file to the (current) default location:
     Windows: the bin directory (where the .exe resides)
     Linux: $HOME/.config/vice/

  (*) if you create one for a controller we do not support yet, please send that
      mapping file to us, so we can include it.

  WE ARE LOOKING FOR WINDOWS AND MACOS DEVELOPERS WHO WANT TO HELP IMPLEMENTING
  AND FIXING FURTHER GAMECONTROLLER RELATED ISSUES - PLEASE GET IN TOUCH!

- Interrupt logic fix: Only when the first IRQ source becomes active, the CPU
  sees the IRQ input line go active; on additional ones, no change is visible.
  So most of the actions that are done should only be done when the first
  IRQ source becomes active, and not on additional ones. (bug #2052)

  IF YOU ARE USING VICE TO DEVELOP/DEBUG, IT IS STRONGLY RECOMMENDED TO UPDATE

- added an option that allows to skip soundchip emulation in warpmode (to increase
  performance, at the cost of some accuracy).

- reSID: scale down filtered voices on 6581
- reSID: scale and clip volume by an arbitrary factor, makes 6581/8580 nearly
  the same volume.
- reSID: implement DAC leakage.
- reSID: fix uninitialized var in old filter
- reSID: Fixed the 8580 filter voltages, now the values really make sense

- CIA: always toggle AM/PM flag when writing 12 o'clock time, no matter if this
  is a change to the hours register or not.

- cleanup of the userport system, devices that do not (and can not) work are no
  more available for a particular machine

- Added C64/C128/SCPU64 palette file created by Kim Lemon to allow for consistency
  in screenshots for lemon64.com.

- fixed handling of warp mode while movie recording is active
- improved ZMBV recording, now handles accurate fractional FPS
- fixed recording with external ffmpeg executable

- fixed polling POTX/POTY when no mouse is active
- added Chalkboard PowerPad emulation
- fixed Rushware Keypad
- fixed Cardco Cardkey keypad
- fixed Atari CX21 Keypad
- fixed SNES pad's raw data
- fixed mapping for keypads attached to joyports
- fix: WOJ Adapter bits where inverted (bug #2026)
- removed support for right and middle button with Amiga and AtariST mice -
  These connect POT lines with GND when pressed, and are open if not, which the
  CBM machines can not detect (since there is no pullup resistor)
- Allow CMD smartmouse time/date to be read and written even if the mouse is not
  grabbed

- When writing .tap values, add the remainder of the current value to the next,
  so overall tap length will be correct.
- do not automatically 'press play' when attaching a t64 image, we don't do this
  for taps either.
- 'press STOP' when detaching a tap image.
- Fix default tape header type (t64) for vic20 and c128 (it should be type 3,
  ie absolute).
- Fix the 'load to basic start' autostart option for tape.

- Reworked the log system. logging to stdout and to an actual file can coexist
  now, each can be selected separately.
- (Optional) support for colors in log messages
- Made ANE/LXA logging options available in all emus, except SCPU

- VICII: init color ram at powerup (bug #2037)

- fsdevice: fixed file name pattern matching.
- fsdevice: Directory loading of "$:" was loading the full directory but should
  have matched no files at all. It is actually a degenerate case where you
  specify an empty pattern and that matches no names. (bug #2047)
- fsdevice: make the first 'line number' in the directory 1 instead of 0. This
  is the partition number on cmd devices, and apparently the c64os setup chokes
  on it being 0

- fixed DigiMAX DAC addresses to make stereo replay work correctly
- RAMLINK: IO1 wouldn't bet setup properly after RAMLINK was turned back on
- fixed RTC core (RTC on CMD FD/HD and RAMLink)

- save 'jammed' status into snapshot for each cpu (bug #1770)

** Buildsystem
--------------

- make configure bail if pkg-config isn't found
- generate linker map files with `--enable-debug`
- configure: barf if `--enable-gtk3ui` is combined with `--without-zlib`
- Added "Game" and "Emulator" categories in the .desktop file template used by
  the `--enable-desktop-files` configure switch. Should fix issues with desktop
  environments not showing the icons after a `make install`.

** C64 fixes
------------

- extended DQBB support, support 16-256k RAM, support C128 mode.
- added support for UC1/UC15/UC2 cartridges
- added support for BMP Data Turbo 2000 cartridge
- correctly assign rr revision when mounting crt file
- various WiC64 related fixes
- Make possible to enable the CP/M cartridge again

** C128 fixes
-------------

- added snapshot support for c128 cartridge system
- Fixed various Z80 timing issues
- Fix: Z80 can not see charrom in c128 mode, but it can in c64 mode (bug #1987)
- added WZ reg for improved bit 3 and 5 status register results. x128 Z80 now passes ZEXALL.
- RAMlink: also exposes open-circuit when internal function roms are off (bug #1963)
- VDC memory is now properly accessed when memory configs differ; vdcdump runs
  in 16KB mode. (bug #1981)

** VIC20 fixes
--------------

- tweak ram init pattern, this makes some known cases that rely on it work
  (AE, Jelly Monsters)
- make the 'exp' command work in the monitor
- added support for 'rabbit tape' cartridge
- added support for 'Super Expander' cartridge
- added support for 'Mikro Assembler' cartridge
- added missing 'bin save', 'crt save', 'flush image' for Final Expansion,
  Megacart, Ultimem, VIC Flash Plugin

- added VIC20 SDL keymaps for UK(symbolic and positional) and DE (positional).

** Plus4 fixes
--------------

- fixed crash when xplus4 runs for a while
- new TED sound logic, heavily inspired by SDL-YAPE
- enabled userport printer
- added support for the 'PETSCII SNES ADAPTER'
- allow 8 controller ports
- make expansion port system (and 'exp' command) work like in other emus, move
  sid-card and digiblaster to cartridges
- improve the case when the TED is reading from floating bus.
- remove support for 'Hannes 4MB' expansion, which was kindof broken, and no
  software exists for even the 1mb variant :)

** PET fixes
------------

- remove the 'load to basic start (tape)' option, since PETs always load absolute
- CRTC emulation fixes (bug #2054)
- fixed PETREU. The masking of the memory bank number allowed too many bank
  address bits, overflowing the allocated memory. (bug #2061)
- fix monitor IO command in range 8800-8fff

** CBM2 fixes
-------------

- remove the 'load to basic start (tape)' option, since CBM2s always load absolute
- Implemented the missing cbm2 cartridge stuff
- handle Machine Power Frequency

** Monitor fixes
----------------

- Remove the weird delayed 'importing' of registers that were changed in the
  monitor. Instead explicitly export before, and import after, each invokation
  of any function that may 'break' into the monitor (and thus lets the user
  change the registers by the R or G command). (see bug #2025, bug #2024.)
  It is strongly recommended, for everyone who uses the monitor for debugging,
  to update to this version - as simply entering and exiting the monitor
  potentially screwed up registers and/or executes the last instruction twice,
  which obviously can lead to all kind of unexpected behaviour.

  THIS BUG EXISTS IN ALL VICE RELEASES PRIOR TO THIS RELEASE. You have been warned :)

- memmap extension: show reads of non initialized ram.
- added read/write as alias for load/store
- implement 'warp on'/'warp off' as advertised.
- limit the output of i and ii commands to a power of two, if the output would
  be smaller than a full screen width
- added monitor command 'tapeoffs <offset>' to set .tap to given offset, or to
  return the current offset when no args are given.
- Improve "help" command.
- Fixed some commands output wrapping against wide and narrow terminals.
- 6809 assembler fixes, "post-byte with submode" was wrong in some cases

** SDL fixes
------------

- added missing ui items for megacart, final expansion, ultimem, vic flash plugin
- Add menu item "Enable joystick menu navigation", enable joystick menu navigation
  by default
- support for Autostart Drag&Drop Mode


** GTK fixes
------------

- added a hidden feature for the 'set to default' button for the CRT sliders:
  hold shift or control, or click with right button, to reset to neutral setting
  instead of whatever (tweaked) defaults. Allows to quickly switch to a setting
  that reproduces a loaded palette 100%
- disable the "Recent files" in file dialogs
- Fix drag-n-drop not working on Windows
- Fix "Reset" button of the mixer widget
- New "ROM Settings" interface. The new interface actually allows users to
  load/save .vrs files, unlike the old interface. No support for ROM set
  archives (.vra), since nobody uses those and they're an unwieldy mess.
- Fixed "Printer Formfeed"
- register provided PETSCII fonts (PetMe, C64 Pro Mono) at startup
- removed DirectX 5 fallback from Win32 joystick driver

- Added "Autostart Drop Mode" option to control autostart behaviour on image drop.
  For Window managers that support it, the user can "override" the behaviour with
  Shift held during drop (attach only) or Alt held (attach and load). Not holding
  a key during drop will use the resource value.

- make GTK monitor window larger by default
- use scroll-wheel to scroll terminal window forth/back, ctrl+scroll wheel to zoom
- show only monospace fonts in the monitor font selection dialog
- Monitor uses PETSCII font (if available/selected)

** c1541 fixes
--------------

- actually check if opening disk images succeeded, Exit with `EXIT_FAILURE` if
  c1541 fails to open any of the images specified on the command line.
