removed modalflags package. modalflags was added very early in the
project. it's neater and simpler to implement command-line modes with
the standard flag package directly
improved log message for unsupported terminal type
remove rand.Seed(time) on startup. rand.Seed() is a deprecated function
Makefile now sets the version string for the project. the version
package tries to set a meaningful version string if the project is not
built with the Makefile
added VERSION command
command line now only accepts true/false as options. previously, the
options were aimed at allowing different syncing methods with the
monitor but that's not needed now
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 emulation package has been unecessary since the amalgamation of the
debugger and play modes. in order to allow switching between the two
modes it was necessary to remove the playmode package and to move all
playmode loops and other considerations into the debugger package. as a
result the abstraction offered by the emulation package is uncessary
-uncapped defaults to true, which is more useful for this mode than
running with the FPS cap enabled
renamed because the -fpscap option for PLAY and DEBUG mode is now very
different and it was confusing to have an option with the same name but
with different semantics
this facilitates A/B testing of two binaries. normally you would want to
prevent a playback with a ROM binary different to one used in the
original recording, but in some instances it is useful
go-wav, statsview and memviz all indirectly used gopkg.in/yaml.v3 which
I do not want to depend upon
WAV functionality is no longer available for wav writing or reading
(supercharger tapes). will try to reintroduce functionality in the
future
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
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
rewinding the main emulation breaks the strict synchronisation
constraints with the comparison emulation. it should be possible to
maintain two parallel rewind instances *and* to maintain the constraints
but I've chosen not to tackle that just yet.
userinput for two emulations synced by RIOT ports. RIOT port
driver/passenger synchronisation ensures user input is seen by the
emulations at the same time (relative to the emulation's television)
does not yet handle RNGs (randomise on startup or the RNG in the DPC or
DPC+ formats yet). we need to add a context type first
added -fpscap to emulate() function (used by both playmode and the
debugger) making it a good alternative to the -display option
getting performance mode to work with an increasingly complex
gui-emulation communication just isn't worth it. it would make the code
too complex.
this paves the way for removing the Emulation interface and using a
straight-forward Emulation type, which will be current Debugger type
renamd. the Debugger type is currently handling the playmode, performing
well and allowing tighter integration of the debugger and playmode.
added terminal.UserQuit sentinal error to better handle quit events.
future versions should probably remove 'running' variable and rely on
this error and filter accordingly
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)
now takes into consideration the attached terminal. added
IsRealTerminal() to terminal.Input interface to support this
reworked script package error messages
I had started to do this work but hadn't finished it.
added gui.ReqEnd so that gui can exit gracefully (save window
preferences etc.) this was previously handled by ReqState
TV frame will never resize if frame is unsynced
Play-screen FPS counter shows target frame frequency
sdlimgui playscreen: screen will not roll on first couple of non-synced
frames. the screen is tolerant of the odd rogue frame.
gui vsync options renamed to monitor sync to clarify distinction wth
emulated television VSYNC
