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 :-)
