ZX Spectrum: ZXHawk bugs

[Asnivor]

Pre-release bug tracking and wip features.

Core Issues

• Beeper implementation has gone wrong somewhere. Playback is slower than it should be and lower in frequency

• Better TZX file detection needed (so that errors in parsing do not just get ignored and the tape isn't just serialized as TAP format)

• Some TZX images throwing exceptions when serializing - examples: Operation Wolf & Operation Thunderbolt. Both use the 'Paul Owens' loading/protection scheme so this might have something to do with it.

• Implement correct parsing (if not implementation, just block length) for ALL valid TZX blocks. Some are still missing

• Emulated TapeDevice should be separated from the normal (ear) beeper device (like it would be on a real spectrum). This would lead to more accurate tape timing emulation.

• Contended memory timings not accurate

• Floating memory bus implementation not accurate (although may be once contended memory is fixed)

• Hard/Soft reset client menu options still greyed out

• Tape AutoLoad mode should be a sync setting

• AY-3-8912 volume control does not work correctly with values under 50

• Has been reported that tape auto-load mode if forced when recording a video

• Reported that when switching tapes the first block is skipped on the new tape (in auto mode)

• After recording a movie the movie details pane shows 60FPS rather than 50 - https://i.imgur.com/ttXOrlL.png

• +3 floppy controller and disk emulation

Reported software glitches

• Power Drift (on 128k machine) text corruption after first championship completed

- [ ] Wonderboy (128k) gfx corruption at Area1 Lvl4 (not emu issue. same happens in FUSE - https://i.imgur.com/ttLEXgU.png)

• ZX Spectrum 128k: "The Deep" Demo (2018) not rendering correctly

• Top Gun (spain) locks up after pressing fire to start

• Star Farce (48k) not showing title screen checkerboard border effect

• Altered Beast (Europe).tzx - Stage2 - character moves by himself with no keypresses

• Beeper audio in Oriental Hero is off for some reason

Tape Media Issues

• Golden Axe 128k TZX loading not completing

• Throws exception when parsing the tape image: Live and let die tzx, Red Heat tzx

• Exception thrown when launching Op. Wolf tap file

Disk Media Issues

• Castlevania (Spectral Interlude) dsk - game hangs on start (because UPD write commands are not yet implemented)

• Iron Lord stalls after title screen

• Shadow of the Beast fails to load

Potential things to do post-release

• +3 disk drive timing emulation

• +3 disk controller persistent write operations & SCAN functions

• Pentagon clone emulation

• Beta disk / TRDOS emulation

• DISCiPLE Interface

• Pentagon gigascreen mod emulation

• Currah MicroSpeech implementation

• Kempston Mouse

• Multiface emulation

Did I just accidentally screw up some checkboxes? O_O

[Asnivor]

Nope, was just a dose of the strikethrough overkill.

Meh.
