- added support for placeholder labels
- improved error messages
- better help command
o debugger
- command template is now labelled
o test
- corrected "expect success" message
- removed REFLECT ON/OFF system
- the performance hit is not that great
o cpu
- added backward branching test
- added branching page fault test
o debugger_test
- increased timeout for rcvOutput()
- removed ErrorID, using the error message as the ID
- works just as well and simplifies maintenance
- the messages should be moved to the relevant packages OR to a
locale package. not sure which yet.
- FromMemory() now creates disassembly instance rather than being a
function attached to the type
- comments and documentation
o debugger
- fixed usage of disassembly.FromMemory()
- the reason we went with the old method for FromMemory() was to aid
in how symbol tables were created and pointed to from debug-memory.
however it was dumb and confusing. problem is now solved correctly
- reworked polycounter to make it easier to generate polycounters of
different bit lengths
o tia/audio
- commented code
o wavwriter
- now saves correctly with correct samplerate
- implemented audio
- using Ron Fries' method as the basis
- removed sample playback - performance of Fries' method is good
enough that we'll never need it again
- sdl audio routines using QueueAudio() - maybe better if we use
callbacks?
- sketched wavwriter AudioMixer - not usable yet
- removed references to SdlPlay and SdlDebug
- constructors for debugger and playmode now expect instances of GUI
and Television, rather than creating them
- this should help future porting efforts
o peripherals
- renamed Events to Actions
- to avoid confusion with Events in the GUI package
o television
- renamed StellaTelevision to television; a better name because
it serves as a reference implementation and is the only television
implementation currently needed.
- originally, PixelRenderers were implemented as Television that
embedded StellaTelevision; it made sense to use a more unique name
- note that we're still keeping and using the Television interface
- reworked specifications file
- cartrdiges no longer return CartridgeListen error if nothing is
done in listen() function
- generating a new error is expensive to do every video cycle and
serves no purpose in this instance
o error
- remove CartridgeListen error
- corrected error handling for GUIEvents
- fixes erroneous crash caused by setting a duplicate mouse break
when emulation is running
- gui event handling now differentiates up and down mouse button
events
- renamed metavideo concept to reflection
- moved metavideo/reflection to its own package
- added ReflectionNotRunning error
- error message shown if overlay is turned on without reflection
processing running
- improved DISPLAY command
o sdl
- type assertion panics now caught in sdl.SetFeture() and returned
as a PanicError
- setup package now uses database package and matches entries to the
specified cartridge and applies the changes listed
- only panel entries supported so far
- database file must be hand written
- renamed FormattedError to AtariError
- renamed NewFormattedError to New
- implemented Is() and IsAny() for more convenient testing
+ changed all error testing to use Is() and IsAny()
- renamed FatalError to PanicError to better indicate the intent
- reworked index bug handling in CPU
- fixed slo opcode defintion (wrong addressing mode specified)
o debugger
- added BUG option to CPU command
- debugger now optionally prints CPU BUG messages on the step it
occurs
- RAM command now has CART option. displays any additional RAM the
cartridge may have
o cartridge
- implemented RAM() command. returns copy of RAM array
- save/restore banks functions are now save/restore state and deal
with cartridge RAM in addition to bank information
o debugger/memory
- better error messages for peek and poke
- reworking of timings
- improved MachineInfo() text
- work on NUSIZ * more to be done
o stella tv
- error if no flyback signal has been sent
o metavideo
- improved metavideo
- now visualises delayed effects
- added state option to frame regression
- records CPU-step granularity recording of the TV state
- intended to test for integrity of TV state recording
- feedback from regression entries now crop filenames to just the
last part of the path
- moved database code into its own package
- correctly filters PlaybackHashErrors - results in "failure" rather
than "error"
o gopher2600 / regression
- added VERBOSE argument to REGRESS RUN mode - prints error messages
- added FAIL argument to REGRESS RUN mode - regression test that end
in an error normally cause the sesssion to end. this option forces
it to continue
o RIOT
- removed randomised start value for INTIM
- makes regression tests more reliable
o television
- renamed BasicTelevision to StellaTelevision
- the source file had been renamed already
- debugger now handles CTRL-Z signals for terminal that have been
put into raw mode; like the colorterm package
- CTRL-C now asks for confirmation
- added EXIT command as an alternative to QUIT
o colorterm
- CTRL-C clears input line if anything has been typed
- input buffer checked for length before writing
- more general and more flexible handling different cartridge
mapping schemes
- implemented parker bros cartridges
o disassembler/debugger
- changes to bank detection to support changes to cartridge module
- a recent refactor caused the vcs to initialise with the basic
television rather than the sdl gui/tv
- this meant that the sdl implementation of MetaSignal was not being
called
o basic television
- scanline extension corrected
o errors
- messages corrected
- added progress meter for playback regression types
o errors
- added FatalError type. intended to be used instead of panic()
o limiter
- created limiter package
- moved sdl fpsLimiter to new package
- added HasWaited() function in additio to Wait() function
- renamed Recorder to Scribe
- any references to script "recording" has been altered
o errors
- some effort expended tidying up error messages display and
construction
- commandline package now uses errors package
o removed panics that would be better served with errors
o removed extraneous calls to fmt.Println and fmt.Printf
- added regression entry listing operation
- added playback regression type
- playback regression makes a local copy of playback script. delete
operation deletes it
- better database key handling
- running of regression tests can now be limited to a list of
specific keys
- renamed HeadlessTV to BasicTelevision
- imagetv and digesttv moved to a single package (called renderers)
- for example, an SDL GUI and a digestTV instance can now use the
same BasicTelevision instance
- hooks now implemented as a Renderer interface
- simplified GetState() interface
o debugger
- debugger now initialises an instance of digestTV, using the same
underlying BasicTelevision as the SDL GUI
- added DIGEST command
- reimplemented system monitor as metavideo
- system monitor was trying to be too general to the point where it
was confusing
- refactored sdl implementation accordingly
o debugging / script
- "script capture" reclassified/renamed as "script recording"
- i want to use capture to refer to the capturing of control input
(joystick, etc.)
o assert
- moved assert package to be a sub-package of hardware/cpu/register
- not required anywhere other than the test packages for cpu and
register
- parse input routines improved
- empty input will repeat the last step command (eg. STEP FRAME)
- added CAPTURE command
- user input is copied to a script file. suitable for future
playback with the SCRIPT command
- scripts now pass through input loop, allowing commands that
control the emulation (like RUN or STEP) to be effective
- reworked ONSTEP and ONHALT commands
- added STICK0 and STICK1 commands
o memory / pia
- improved RAM debugging output
