ZX Spectrum: ZXHawk bugs

Asnivor commented 6 years ago

Pre-release bug tracking and wip features.

Core Issues

[x] Beeper implementation has gone wrong somewhere. Playback is slower than it should be and lower in frequency
[x] 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)
[x] 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.
[x] Implement correct parsing (if not implementation, just block length) for ALL valid TZX blocks. Some are still missing
[x] 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.
[x] Contended memory timings not accurate
[x] Floating memory bus implementation not accurate (although may be once contended memory is fixed)
[x] Hard/Soft reset client menu options still greyed out
[x] Tape AutoLoad mode should be a sync setting
[x] AY-3-8912 volume control does not work correctly with values under 50
[x] Has been reported that tape auto-load mode if forced when recording a video
[x] Reported that when switching tapes the first block is skipped on the new tape (in auto mode)
[x] After recording a movie the movie details pane shows 60FPS rather than 50 - https://i.imgur.com/ttXOrlL.png
[x] +3 floppy controller and disk emulation

Reported software glitches

[x] 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)

[x] ZX Spectrum 128k: "The Deep" Demo (2018) not rendering correctly
[x] Top Gun (spain) locks up after pressing fire to start
[x] Star Farce (48k) not showing title screen checkerboard border effect
[x] Altered Beast (Europe).tzx - Stage2 - character moves by himself with no keypresses
[x] Beeper audio in Oriental Hero is off for some reason

Tape Media Issues

[x] Golden Axe 128k TZX loading not completing
[x] Throws exception when parsing the tape image: Live and let die tzx, Red Heat tzx
[x] Exception thrown when launching Op. Wolf tap file

Disk Media Issues

[x] Castlevania (Spectral Interlude) dsk - game hangs on start (because UPD write commands are not yet implemented)
[x] Iron Lord stalls after title screen
[ ] Shadow of the Beast fails to load

Potential things to do post-release

Did I just accidentally screw up some checkboxes? O_O

Nope, was just a dose of the strikethrough overkill.

Meh.
