Update to v097r28 release.
byuu says:
Changelog: (all WSC unless otherwise noted)
- fixed LINECMP=0 interrupt case (fixes FF4 world map during airship
sequence)
- improved CPU timing (fixes Magical Drop flickering and FF1 battle
music)
- added per-frame OAM caching (fixes sprite glitchiness in Magical Drop,
Riviera, etc.)
- added RTC emulation (fixes Dicing Knight and Judgement Silversword)
- added save state support
- added cheat code support (untested because I don't know of any cheat
codes that exist for this system)
- icarus: can now detect games with RTC chips
- SFC: bugfix to SharpRTC emulation (Dai Kaijuu Monogatari II)
- ( I was adding the extra leap year day to all 12 months instead of
just February ... >_< )
Note that the RTC emulation is very incomplete. It's not really
documented at all, and the two games I've tried that use it never even
ask you to set the date/time (so they're probably just using it to count
seconds.) I'm not even sure if I've implement the level-sensitive
behavior correctly (actually, now that I think about it, I need to mask
the clear bit in INT_ACK for the level-sensitive interrupts ...)
A bit worried about the RTC alarm, because it seems like it'll fire
continuously for a full minute. Or even if you turn it off after it
fires, then that doesn't seem to be lowering the line until the next
second ticks on the RTC, so that likely needs to happen when changing
the alarm flag.
Also not sure on this RTC's weekday byte. On the SharpRTC, it actually
computes this for you. Because it's not at all an easy thing to
calculate yourself in 65816 or V30MZ assembler. About 40 lines of code
to do it in C. For now, I'm requiring the program to calculate the value
itself.
Also note that there's some gibberish tiles in Judgement Silversword,
sadly. Not sure what's up there, but the game's still fully playable at
least.
Finally, no surprise: Beat-Mania doesn't run :P

Update to v097r26 release.
byuu says:
Changelog:
- WS: fixed 8-bit sign-extended imul (fixes Star Hearts completely,
Final Fantasy world map)
- WS: fixed rcl/rcr carry shifting (fixes Crazy Climber, others)
- WS: added sound DMA emulation (Star Hearts rain sound for one example)
- WS: added OAM caching, but it's forced every line for now because
otherwise there are too many sprite glitches
- WS: use headphoneEnable bit instead of speakerEnable bit (fixes muted
audio in games)
- WS: various code cleanups (I/O mapping, audio channel naming, etc)
The hypervoice channel doesn't sound all that great just yet. But I'm
not sure how it's supposed to sound. I need a better example of some
more complex music.
What's left are some unknown register status bits (especially in the
sound area), keypad interrupts, RTC emulation, CPU prefetch emulation.
And then it's all just bugs. Lots and lots of bugs that need to be
fixed.
EDIT: oops, bad typo in the code.
ws/ppu/ppu.cpp line 20: change range(256) to range(224).
Also, delete the r.speed stuff from channel5.cpp to make the rain sound
a lot better in Star Hearts. Apparently that's outdated and not what the
bits really do.

Update to v097r24 release.

Changelog:
- WS: fixed bug when IRQs triggered during a rep string instruction
- WS: added sprite attribute caching (per-scanline); absolutely massive
speed-up
- WS: emulated limit of 32 sprites per scanline
- WS: emulated the extended PPU register bit behavior based on the
DISP_CTRL tile bit-depth setting
- WS: added "Rotate" key binding; can be used to flip the WS display
between horizontal and vertical in real-time
The prefix emulation may not be 100% hardware-accurate, but the edge
cases should be extreme enough to not come up in the WS library. No way
to get the emulation 100% down without intensive hardware testing.
trap15 pointed me at a workflow diagram for it, but that diagram is
impossible without a magic internal stack frame that grows with every
IRQ, and can thus grow infinitely large.
The rotation thing isn't exactly the most friendly set-up, but oh well.
I'll see about adding a default rotation setting to manifests, so that
games like GunPey can start in the correct orientation. After that, if
the LCD orientation icon turns out to be reliable, then I'll start using
that. But if there are cases where it's not reliable, then I'll leave it
to manual button presses.
Speaking of icons, I'll need a set of icons to render on the screen.
Going to put them to the top right on vertical orientation, and on the
bottom left for horizontal orientation. Just outside of the video
output, of course.
Overall, WS is getting pretty far along, but still some major bugs in
various games. I really need sound emulation, though. Nobody's going to
use this at all without that.
