f8083db181 Added raddad772/jsmoo's Z80 test runner
Special thanks to raddad772 https://github.com/raddad772

Also added some fixes to the Z80 for panicking math operations, but
it still won't complete due to an unimplemented instruction

527f65c69b Refactored audio to use ClockedQueue
It now actually checks the clock and tries to mix the audio in sync
relative to the clock, but the cpal output doesn't yet try to sync
to the StreamInstant time.  Sound seems a lot better on chrome in
wasm, but and kind of better on firefox despite frame skipping not
being supported yet, but it's way slower for some reason (12fps)

074d29c023 Modified ym2612 to use 16 bit signed number a bit sooner 2023-04-30 16:48:40 -07:00
transistor
71cd47466b Getting closer on the ym2612 implementation
It now sort of sounds like the main instrument, but the drums and bass
aren't there, and I'm not sure why.  I'm pretty sure the envelope and
phase generators are working, and there is feedback although it might
not be correct.  There's no LFO but that isn't used by Sonic 1 from
the register writes at least.

transistor
03561f1427 Fixed a bug in the frequency setting code for ym2612
It was previously only updating the frequency if the A0 registers
were written last, but now it works the way the rate code does, using
the cached register values to set the frequency whenever a register
is written to.  It also stores the fnumber and block in the operator
which I guess would be needed eventually if I want to save and restore
state.

dcc3c97dd6 Additional ym2612 improvements 2023-04-24 21:29:42 -07:00
transistor
31faf70d97 Fixed many bugs in ym2612, and switched to square wave
- The envelope generator wasn't working as it should have, minor issues
  with the limits and whether to use 10-bit or 12-bit values (more to come)
- fixed issues with sustain level where it was always set to 0
- fixed release rate and levels to make them 5-bit and 10-bit numbers
  respectively, so they match the others
- switched from SineWave to SquareWave and this alone made it go from
  terrible and muddy to not that far off.  I probably need to completely
  change the output

- also included an attempt at removing HostData, still needed for an
  interrupt that is triggered by user input

5740550c95 Non-working implementation of the ym2612 envelope
It does something, but doesn't work as it should.  It could be a few
things including the on/off signal being too slow due to how time
works in the sample generation, but I wanted to at least commit what
I have.  It seems to work roughly right according to the forum post
that describes the chip's operation in detail, but there could still
be some glaring bugs

941c793523 Added pixel encoding, requested by frontend
The hope was that this would reduce the amount of copying and bit
shifting required by the frontend to get the data on screen, but
it doesn't seem to offer much advantage, surprisingly.  I'll leave
it in though.  There are a few other minor tweaks included here to
try to improve the performance a bit
