Hardware	Disabled tape trap auto-stop (this is more trouble than its worth - tzx formats should include 'stopthetape' blocks anyway, and tap files are generally junk and should be discouraged)	2018-03-13 14:08:53 +00:00
Machine	new IPSG interface ahead of trying to A/B a version of the ColecoHawk AY-3-8910	2018-03-13 14:00:29 +00:00

ZXHawk

At the moment this is experimental and is still being worked on.

Implemented and working (as far as I can tell)

IEmulator
ZX Spectrum 48k, 128k, +2 & +2A models
ULA video output (implementing IVideoProvider)
ULA Mode 1 VBLANK interrupt generation
IM2 Interrupts and DataBus implementation (thanks Aloysha)
Beeper/Buzzer output (implementing ISoundProvider)
AY-3-8912 sound chip implementation (stereo or mono options available as a setting)
Keyboard input (implementing IInputPollable)
Default keyboard keymappings
Kempston, Cursor and Sinclair (Left & Right) joysticks emulated
Tape device that will load spectrum games in realtime (*.tzx and *.tap)
Most tape protection/loading schemes that I've tested are currently working
IStatable
ISettable core settings
IDebuggable (for what it's worth)
DeterministicEmulation as a SyncSetting, LagFrame detection and FrameAdvance render & renderSound bools respected (when DeterministicEmulation == false)
Tape auto-loading routines (as a setting - default ON)
Basic tape block navigation (NextBlock, PrevBlock)
Tape-related OSD messages (verbosity level configured in settings)

Work in progress

ZX Spectrum +3 emulation (partially working, see below)
Exact emulator timings
Floating memory bus emulation
TASStudio (need to verify that this works as it should)

Not working

+3 disk drive - no implementation yet
Hard & Soft Reset menu options in the client (they are greyed out for some reason)

Help needed

I'm not a TASer, i've never TASed before. It would be really useful if someone (anyone) can build this branch and test this core from a TAS-workflow / TAStudio perpective. There may still be some work to do an exact timings and memory contention, but otherwise this core is able to play the majority of speccy games out there.
