notifications interface instance moved to environment from
cartridgeloader. the cartridgeloader package predates the environment
package and had started to be used inappropriately
simplified how notifications.Notify() is called. in particular the
supercharger fastload starter no longer bundles a function hook. nor is
the cartridge instance sent with the notification
this replaces the PAL60 specification. PAL60 can still be specified on
the command line (and embedded in ROM filenames) but it is now treated
exactly the same as PAL
AudioTick() function in tracker interface accepts TrackerEnvironment
instance. tracker implementation differentiates emulation instances and
records AudioTick() information accordingly
float32 pair defined as ports.EventDataPaddle
added functions to convert the float32 to and from a playback entry.
conversion from the playback entry tolerates a single float32 value
meaning that old recording files will work
rename plugging.PortLeftPlayer and plugging.PortRightPlayer to just
plugging.PortLeft and plugging.PortRight
curated package predated the standard errors package introduced in
go1.13
the standard package does a better job of what curated attempted to do
the change of package also gave me a opportunity to clean up the error
messages a little bit
the reset can be done automatically but as an optional operation. it has
been discovered that in some situations more preparation is required
before the cartridge is reset. particularly, ACE/ELF type cartridges
where the ARM may executed before the coprocessor disasm/developer
packages are initialised and attached
PERIPHERAL command now accepts AUTO parameter. this will (re)fingerprint
the cartridge and insert the "detected" peripheral
implementation temporary in lieu of an improved setup package
thumbnailer was running in a different goroutine to that which the state
being used to generate the thumbnail was create in. there's no way of
making that safe except through mutexes or similar. that's too much
overhead for something as inconsequential as a timeline thumbnailer
timeline thumbnailer now runs in the same goroutine as the main
emulation, bypassing these problems. scheduling of when thumbnailer runs
is now done manually
"Live" TIA Revision values replaced with atomics. small performance
improvement
moved controllers and savekeys package to new peripherals package
removed auto controller
changed lazy.Controllers to lazy.Peripherals and Controllers window to
Peripherals window
changed CONTROLLER command to PERIPHERAL command. removed AUTO option
added savekey as an option to PERIPHERAL command and Peripheral window
addresses and bus interface removed and split into cpubus and chipbus
packages.
ReadZeroPage() no longer has any distinction from normal Read()
function.
playback/recorder and driven input systems moved out of the the ports
package and into a new input package. how the input systems interact has
been clarified and improved - for example, it is now posssible for a
playback file to be used to drive two emulations for comparison purposes
the debugger startup procedure has been clarified with two distinct
startup functions for playmode and debugger - each of which take
different arguments. the clarity has allowed the reintroduction of
recording and playback to the main play mode
this is now used when passing events and event data around. it also
records the port and time (in TV coordinates) which are required by
driver/passenger synchronisation and playback recording
removed television interfaces from signal package and moved the
interfaces to where they are needed
the thumbnailer does the actual emulation in a new goroutine so there's
no lag here but it's necessary to PushRawEvent() so that
rewind.GetState() doesn't race
new counter package added (sub-package of reflection)
this new counting method is fast enough to be run while in playmode,
which means that historical timeline information is immediately
available in the debugger
switch between debugger and playmode with F6 or backtick key
pakage debugger remains for now but it will be renamed to emulator or
something like that. playmode package removed.
commandline options for both debugger and playmode are the same
currently, with some playmode features being lost (temporarily)
added PeripheralID type to complement PortsID type. renamed keyboard
peripheral to keypad, which is more accurate and removes any potential
confusion with the physical keyboard the user might be using
common TIA variations added to tia package
revisions preferences window in sdlimgui
key names in prefs package can now contain digits in addition to letters
TIA sub-components no longer pass values around in return values. it
turns out to be far cheaper computationally to store calculated values
in the TIA sub-types and retrieving them as required.
on my machine this turns out to be around 2fps saving
cart ram/static areas show changes across time
supercharger TV reset after tape load no longer resets frame number.
this affected the rewind system and how it stores historical data.
improved responsiveness of service loop polling
VCSReturnChannel so the television can inform the VCS about a change in
television spec. The VCS uses this information to forward clock
information to the cartridge.Step function
DPC and DPC+ music generators now use correct VCS clock value in all
instances
this affected regression tests when random state was switched on
- although regression tests reset the preferences to a known state
the timer was not affected when the VCS was reset, causing some
tests to fail inexplicably
result of changing rewind maxentries value displayed correctly in win_control
timer randomised on startup (if preference selected)
changing symbols preference updates disasm window vertical alignment
file selector:
- scrolls to top on directory change
- centres on current ROM when first opened
help note for the -state flags (REGRESS ADD)
changed default window position for timer window
updates attached pixelrenderers. added Refresh() function and added
'refreshing' flag to SetPixel()
cpu and tia memory references updated on rewind
fixed rewind.Append()
