0.9 (02-Mar-2012)
-----------------

* Now uses comes with appropriate icons for OS4, MorphOS
  and AROS.
* Audio sync problems fixed in AVI recordings
* Various optimisations to the display routines
* 6502 emulation now includes all illegal opcodes
* Now includes an option to emulate the 6502 at various
  clock speeds from 1Mhz to 64Mhz (the rest of the hw
  is emulated at normal speed).
* Tape saving is now implemented. CSAVE/STORE will save
  to a standard tap file. You can also capture all tape
  output to a new .ORT format, which will record the
  actual output waveform from the tape port.
* Changes to disks are now automatically saved back to
  the disk image file. The old behaviour can still be
  selected from the config file.
* Reformatted the VIA panel in the debugger (thanks to
  Twilighte for the suggestion)
* Printer emulation now filters out non-ascii chars as
  a workaround for the phantom printer output (this is
  temporary until a proper fix is found)
* Added a PAL ghosting simulation to the GL renderer
* Switching between OpenGL and software rendering on the
  fly no longer causes hang-on-exit problems.
* Added NMI, reset and IRQ vector display in the
  debugger (thanks to Twilighte for the suggestion!)
* Keyboard can now only be read when the AY direction
  register is set up correctly (thanks to Chema for
  pointing this out).
* Added experimental snapshot functionality (use with
  caution!)
* The Oric lightpen is now emulated (thanks to Stefan
  Haubenthal for his help)


0.8 (19-Nov-2011)
-----------------

* Proper credits for Francois Revol
* Uses "T" as a shortcut for insert tape <revolf>
* Clipboard support on BeOS & OS X <revolf>
* Fixed OVRAM update glitch <stefan h>
* Link to the google code page from the about window
* Set/clear breakpoints by double clicking addresses
  in the registers window.
* Toggle CPU flags by double clicking on them
* Chain loading multiple tape images no longer
  disables turbo tape.
* Modifications made in the monitor are now
  highlighted. Changes since the last monitor entry
  are still shown, but are replaced by modifications
  highlighting as soon as you change anything.
* No longer crashes if a ROM file is missing <stefan h>
* Various updates to included ROM symbol files
  <revolf/stefan h>
* Fixed broken ROR ABS,X
* Video preview in the monitor now shows the current
  state of video-ram rather than the raster based
  emulation.
* CPU/VIA interaction is now pretty much cycle
  exact (thanks to DBug for his extensive debugging!).
* Fixed cycle counting during IRQ
* Fixed broken cycle counts for zero page index
  addressing modes across page boundaries.
* Fixed DEC ABS cycle count
* Disk sector writes now start with 0xfb instead of 0xf8


0.7 (20-Sep-2010)
-----------------

General:

* Added Telestrat support, although it doesn't work
  enough to be useful yet.
* Added Pravetz-8D support, although the Pravetz/
  Apple disk system is not supported yet.
* Added some error checking to the command-line
  argument parsing.
* Standard return codes on exit.
* IJK and PASE/Altai joystick emulation (thanks to
  Twilighte and Stefan Haubenthal for info)
* For all ROM image files, Oricutron now looks for
  a corresponding ".pch" file with information about
  the ROM, such as patch addresses for turbotape,
  or the keyboard layout expected by the ROM.
* ROM filenames are now specified in the config
  file.
* Now uses SDL_RWops to load images and ROMs for
  better cross-platform compatibility (thanks
  to revolf).
* The disk emulation now updates sector CRCs when
  writing to disk (oops!)
* OpenGL rendering mode with optional display
  aspect stretching.
* Optional scanline simulation.
* You can toggle fullscreen mode from the menus.
* Software rendering mode now has a 32bit mode
  as well as 16bit. Oricutron attempts to select
  the optimal mode, but it can be overridden in
  the config file (thanks to Alexandre Devert)

Debugger/Monitor:

* For all ROM image files, Oricutron now looks for
  a corresponding ".sym" file with symbols for the
  debugger when that ROM is active.
* Disassembling to file now uses full symbol names.
* Supports CC65/VICE style label files (thanks to
  Stefan Haubenthal).
* You can now create or move symbols while using
  the assembler.
* You can create, delete and export symbols from
  the monitor commandline.
* Added a memory modify command.
* Fixed breakpoint behaviour. Before, when the CPU
  hit a breakpoint, the rest of the emulation
  would execute for the cycles of that command,
  even though the command wasn't executed.

Amiga/MorphOS:

* Pressing help brings up the AmigaGuide readme.
  (thanks to Stefan Haubenthal)

BeOS:

* You can paste from the clipboard with F9. (thanks
  to revolf)
* Native messagebox and file requester. (thanks to
  revolf)

OSX:

* Native messagebox and file requester. (thanks to
  revolf)


0.6 (15-Jun-2010)
-----------------

* If you type CLOAD"", THEN insert a tape, it will
  now load properly even with turbotape enabled.
* Now outputs the mono audio as two identical stereo
  channels again. It seems some targets don't like
  mono audio.
* Fixed some compilation warnings
* The files/dirs in the SDL filerequesters are
  now sorted (thanks ibisum!)
* AY Envolope Per H now shown correctly in debugger
* Included AmigaGuide version of readme (thanks
  to Stefan Haubenthal)
* Better argument parsing (thanks Revolf)
* Navigating in menus with cursor keys now cycles
  round at the top/bottom.
* Menus have keyboard shortcuts
* Auto-insertion of tapes should work better
* Various minor fixes


0.5 (24-Feb-2010)
-----------------

* Preliminary VSync hack support (based on guess work).
* The windows port has an Oric icon.
* If saving a disk image fails, you are now notified
  via the info popup.
* Amiga & MorphOS ports now have a version string.
* Fixed the broken symbols in the debugger.
* You can now override default settings with a config
  file. An example one is provided.
* Warp speed is properly warpy again ;-)
* Added tape and AVI capture status icons.
* Shift register is a little bit better.
* Oric printer output works again.
* Long disk image filenames are truncated nicely now
  (like the tape filenames).
* Attempted to reduce calls to SDL_LockAudio()/
  SDL_UnlockAudio() in the emulation loop.


0.4 (16-Feb-2010)
-----------------

* AY sound is (again) a lot better
* Fixed keyboard issues introduced with 0.3
* Improved menu navigation
* Tape noise is available again, although it doesn't
  work properly
* VIA shift register is partially implemented
* Disk writing is supported. The disk image won't
  be changed until you hit F7 (or shift-F7) to save
  changes back to the image file.
* New status bar with disk status icons


0.3 (12-Feb-2010)
-----------------

* CPU/VIA timing should now be balls-on, unless I made
  a mistake somewhere ;-)
* AY sound should be a lot more accurate. Also, sample
  playback is now working. Still not perfect, but its
  getting there!
* Added (experimental) AVI export. Press F10 to record
  and again to stop. Don't be surprised if it doesn't
  work for some reason.
* OS4 and Windows now use their respective standard
  operating system file requesters. Other ports will use
  the crappy built in one, unless someone adds platform
  specific support.
* The oric printer is emulated. All printer output
  is appended to "printer_out.txt".


0.2 (08-Feb-2010)
-----------------

* Fullscreen now works properly on OS4
* A LOT more disk based software will work that just
  froze up before.
* Much, much better audio
* New layout for the AY info in the debugger


0.1 (06-Feb-2010)
-----------------

General:

 * Now called "Oricutron". Apparently Oriculator is
   rude in some languages :-)
 * Works well enough to deserve "0.1" instead of "0.0.x"
 * You can now auto-insert a tape by passing its name to
   CLOAD. If you need to "CLOAD" a specific file within
   a tape image, you can disable this feature.
 * Fixed broken FPS display
 * Fixed a condition where a filehandle wouldn't get closed.
 * Added a 16k Oric-1 mode
 * Added commandline options
 * Fixed ADC/SBC overflow flag bug
 * Mouse click now opens the main menu
 * Fixed hard lockup when executing BRKs constantly
 * Fixed B flag bug
 * Fixed carry flag in BCD mode SBC
 * Fixed behaviour or N and Z flags in decimal mode
 * Fixed flag issue in TXS
 * Emulation speed is no longer tied to the audio callback,
   enabling more reasonably sized audio buffers.
 * 60Hz attribute emulated
 * Fullscreen mode (only available via commandline for now)

Disk:

 * Massive improvements to disk support. Reading works
   for most things (only Read Track is not implemented
   yet). Writing is not implemented at all.
 * Added support for the Jasmin disk controller. Press
   F4 to reboot in disk mode when jasmin is enabled.

Debugger/Monitor:

 * Added memwatch window
 * Added symbols support
 * Implemented help command (?)
 * F11 traces code without going into subroutines
   (or Shift+F10 on Amiga keyboards)
 * F12 now skips instructions
 * Breakpoints now survive any reset unless the machine type
   is changes.
 * You can now set breakpoints on memory accesses as well
   as program execution
 * Memory reads from monitor no longer cause side effects
   for VIA and disk


0.0.2 (06-Apr-2009)
-------------------

 * Blink attribute emulated
 * Removed the need for a mutex in the sound framework, which
   gives a good speed up.
 * AY sound works, more or less (needs much more work :)
 * FPS display is now averaged over 8 frames
 * Sends an extra zero-byte at the end of .tap files. This seems
   to make more tapes load (e.g. MazezaM), but I don't know why.
   Needs further investigation.


0.0.1 (31-Mar-2009)
-------------------

 * Just an early preview. Please do not report bugs or
   judge it too harshly. The emulator is not really
   ready for a release yet :-)
