Changelog:
- gba/cpu: slight speedup to CPU::step()
- processor/arm7tdmi: fixed about ten bugs, ST018 and GBA games are
now playable once again
- processor/arm: removed core from codebase
- processor/v30mz: code cleanup (renamed functions; updated
instruction() for consistency with other cores)
It turns out on my much faster system, the new ARM7TDMI core is very
slightly slower than the old one (by about 2% or so FPS.) But the
CPU::step() improvement basically made it a wash.
So yeah, I'm in really serious trouble with how slow my GBA core is now.
Sigh.
As for higan/processor ... this concludes the first phase of major
cleanups and rewrites.
There will always be work to do, and I have two more phases in mind.
One is that a lot of the instruction disassemblers are very old. One
even uses sprintf still. I'd like to modernize them all. Also, the
ARM7TDMI core (and the ARM core before it) can't really disassemble
because the PC address used for instruction execution is not known prior
to calling instruction(), due to pipeline reload fetches that may occur
inside of said function. I had a nasty hack for debugging the new core,
but I'd like to come up with a clean way to allow tracing the new
ARM7TDMI core.
Another is that I'd still like to rename a lot of instruction function
names in various cores to be more descriptive. I really liked how the
LR35902 core came out there, and would like to get that level of detail
in with the other cores as well.
[This version, with the internal version number changed back to "v100",
replaced the original v100 source archive on byuu.org soon after v100's
release, because it fixes important bugs in that version. --Ed]

Changelog:
- fixed default paths for Sufami Turbo slotted games
- moved WonderSwan orientation controls to the port rather than the device
- I do like hex_usr's idea here; but that'll need more consideration;
so this is a temporary fix
- added new debugger interface (see the public topic for more on that)

Changelog:
- WS: fixed lods, scas instructions
- WS: implemented missing GRP4 instructions
- WS: fixed transparency for screen one
- WSC: added color-mode PPU rendering
- WS+WSC: added packed pixel mode support
- WS+WSC: added dummy sound register reads/writes
- SFC: added threading to SuperDisc (it's hanging for right now; need to
clear IRQ on $21e2 writes)
SuperDisc Timer and Sound Check were failing before due to not turning
off IRQs on $21e4 clear, so I'm happy that's fixed now.
Riviera starts now, and displays the first intro screen before crashing.
Huge, huge amounts of corrupted graphics, though. This game's really
making me work for it :(
No color games seem fully playable yet, but a lot of monochrome and
color games are now at least showing more intro screen graphics before
dying.
This build defaults to horizontal orientation, but I left the inputs
bound to vertical orientation. Whoops. I still need to implement
a screen flip key binding.

Got it. Wow, that didn't hurt nearly as much as I thought it was going
to.
Dropped from 127.5fps to 123.5fps to use Natural/Integer for
(u)int(8,16,32,64).
That's totally worth the cost.

This is a few days old, but oh well.
This WIP changes nall,hiro,ruby,icarus back to (u)int(8,16,32,64)_t.
I'm slowly pushing for (u)int(8,16,32,64) to use my custom
Integer<Size>/Natural<Size> classes instead. But it's going to be one
hell of a struggle to get that into higan.
byuu says:
All 256 instructions implemented fully. Fixed a major bug with
instructions that both read and write to ModRM with displacement.
Riviera now runs into an infinite loop ... possibly crashed, possibly
waiting on interrupts or in to return something. Added a bunch of PPU
settings registers, but nothing's actually rendering with them yet.
