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.

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.
