Update to v102r24 release.
byuu says
Changelog:
- FC: fixed three MOS6502 regressions [hex\_usr]
- GBA: return fetched instruction instead of 0 for unmapped MMIO
(passes all of endrift's I/O tests)
- MD: fix VDP control port read Vblank bit to test screen height
instead of hard-code 240 (fixes Phantasy Star IV)
- MD: swap USP,SSP when executing an exception (allows Super Street
Fighter II to run; but no sprites visible yet)
- MD: grant 68K access to Z80 bus on reset (fixes vdpdoc demo ROM from
freezing immediately)
- SFC: reads from $00-3f,80-bf:4000-43ff no longer update MDR
[p4plus2]
- SFC: massive, eight-hour cleanup of WDC65816 CPU core ... still not
complete
The big change this time around is the SFC CPU core. I've renamed
everything from R65816 to WDC65816, and then went through and tried to
clean up the code as much as possible. This core is so much larger than
the 6502 core that I chose cleaning up the code to rewriting it.
First off, I really don't care for the BitRange style functionality. It
was an interesting experiment, but its fatal flaw are that the types are
just bizarre, which makes them hard to pass around generically to other
functions as arguments. So I went back to the list of bools for flags,
and union/struct blocks for the registers.
Next, I renamed all of the functions to be more descriptive: eg
`op_read_idpx_w` becomes `instructionIndexedIndirectRead16`. `op_adc_b`
becomes `algorithmADC8`. And so forth.
I eliminated about ten instructions because they were functionally
identical sans the index, so I just added a uint index=0 parameter to
said functions. I added a few new ones (adjust→INC,DEC;
pflag→REP,SEP) where it seemed appropriate.
I cleaned up the disaster of the instruction switch table into something
a whole lot more elegant without all the weird argument decoding
nonsense (still need M vs X variants to avoid having to have 4-5
separate switch tables, but all the F/I flags are gone now); and made
some things saner, like the flag clear/set and branch conditions, now
that I have normal types for flags and registers once again.
I renamed all of the memory access functions to be more descriptive to
what they're doing: eg writeSP→push, readPC→fetch,
writeDP→writeDirect, etc. Eliminated some of the special read/write
modes that were only used in one single instruction.
I started to clean up some of the actual instructions themselves, but
haven't really accomplished much here. The big thing I want to do is get
rid of the global state (aa, rd, iaddr, etc) and instead use local
variables like I am doing with my other 65xx CPU cores now. But this
will take some time ... the algorithm functions depend on rd to be set
to work on them, rather than taking arguments. So I'll need to rework
that.
And then lastly, the disassembler is still a mess. I want to finish the
CPU cleanups, and then post a new WIP, and then rewrite the disassembler
after that. The reason being ... I want a WIP that can generate
identical trace logs to older versions, in case the CPU cleanup causes
any regressions. That way I can more easily spot the errors.
Oh ... and a bit of good news. v102 was running at ~140fps on the SNES
core. With the new support to suspend/resume WAI/STP, plus the internal
CPU registers not updating the MDR, the framerate dropped to ~132fps.
But with the CPU cleanups, performance went back to ~140fps. So, hooray.
Of course, without those two other improvements, we'd have ended up at
possibly ~146-148fps, but oh well.

Update to v074r11 release.
byuu says:
Changelog:
- debugger compiles on all three profiles
- libsnes compiles on all three platforms (no API changes to libsnes)
- memory.cpp : namespace memory removed (wram -> cpu, apuram -> smp,
vram, oam, cgram -> ppu)
- sa1.cpp : namespace memory removed (SA-1 specific functions merged
inline to SA1::bus_read,write)
- GameBoy: added serial link support with interrupts and proper 8192hz
timing, but obviously it acts as if no other GB is connected to it
- GameBoy: added STAT OAM interrupt, and better STAT d1,d0 mode values
- UI: since Qt is dead, I've renamed the config files back to bsnes.cfg
and bsnes-geometry.cfg
- SA1: IRAM was not syncing to CPU on SA-1 side
- PPU/Accuracy and PPU/Performance needed Sprite oam renamed to Sprite
sprite; so that I could add uint8 oam[544]
- makes more sense anyway, OAM = object attribute memory, obj or
sprite are better names for Sprite rendering class
- more cleanup
