The game manifest field names are now officially set in stone. I won't
change them again, I'll only add new fields if required.
As for the values in the field, I'm still undecided on the manufacturer
of the ST018, and I could be talked into different identifiers for the
Super Game Boy (SGB1/SGB2, DMG/MGB, or just ICD(2)?)
The board manifest format is still in flux, as is the choice of what to
name firmware files (it's between manufacturer and architecture, where
I'm leaning toward the latter currently.)
Board memory to Game memory mappings will require both the manufacturer
and architecture fields to match.
I'll be updating doc.byuu.org soon with the finalized game manifest
format.

Changelog:
- manifest: memory/battery now resides under type at
memory/type/battery
- genius: volatile option changed to battery; auto-disables when not
RAM or RTC type
- higan: added new Emulator::Game class to parse manifests for all
emulated systems consistently
- Super Famicom: board manifest appended to manifest viewer now
- Super Famicom: cartridge class updated to use Emulator::Game objects
- hiro: improve suppression of userland callbacks once
Application::quit() is called
- this fixes a crash in genius when closing the window with a tree
view item selected
My intention is to remove Emulator::Interface::sha256(), as it's not
really useful. They'll be removed from save states as well. I never
bothered validating the SHA256 within them, because that'd be really
annoying for ROM hackers.
I also intend to rename Emulator::Interface::title() to label() instead.
Most everything is still broken. The SNES still needs all the board
definitions updated, all the other cores need to move to using
Emulator::Game.

Changelog:
- higan, icarus, genius: new manifest syntax (work in progress)
Pretty much only LoROM and HiROM SNES games will load right now, and RAM
will only work right if the save.ram file already exists to pull its
file size from (a temporary cheap hack was used.)
Basically, I'm just getting this out there for evaluation.
One minor errata is that I switched icarus to using “memory/battery” to
indicate battery-backed RAM, whereas genius still uses “memory/volatile”
to indicate non-battery-backed RAM.
I intend to make it “memory/battery” in genius, and have the field
auto-enable when RAM or RTC is selected for type (obviously allowing it
to be unchecked for volatile memory.)
I need to update all 64 production boards, and 25 of 29 generic boards,
to use the new slot syntax; and I also need to update every single core
in higan to use the new manifest game syntax. I want to build out a
generic manifest game parser that all emulation cores will use.
Once I finish this, I'll also need to write a database converter to
update all of my licensed game dumps to the new database syntax.
I also need to write up something for doc.byuu.org explaining the new
manifest game syntax. The manifest board syntax will still be “internal”
and subject to revisions, but once v107 is out, the gamepak manifest
format will be set in stone sans extensions.

Changelog:
- Super Game Boy: for the 50th time, higan won't segfault if you
cancel the Game Boy cartridge load request
- icarus: moved to new manifest syntax for all remaining systems
- Game Boy: moved to new manifest syntax
Errata:
- Game Boy: save RAM does not appear to be working for some reason
- Famicom: higan won't even start to run this system; it just acts
like a cartridge was never loaded ...
- cores outside of the Super Famicom and Game Boy/Color will not run
due to icarus/higan manifest syntax differences

Changelog:
- PCE: split VCE from VDC
- HuC6280: changed bus from (uint21 addr) to (uint8 bank, uint13 addr)
- added SuperGrafx emulation (adds secondary VDC, plus new VPC)
The VDC now has no concept of the actual display raster timing, and
instead is driven by Vpulse (start of frame) and Hpulse (start of
scanline) signals from the VCE. One still can't render the start of the
next scanline onto the current scanline through overly aggressive
timings, but it shouldn't be too much more difficult to allow that to
occur now. This process incurs quite a major speed hit, so low-end
systems with Atom CPUs can't run things at 60fps anymore.
The timing needs a lot of work. The pixels end up very jagged if the VCE
doesn't output batches of 2-4 pixels at a time. But this should not be a
requirement at all, so I'm not sure what's going wrong there.
Yo, Bro and the 512-width mode of TV Sports Basketball is now broken as
a result of these changes, and I'm not sure why.
To load SuperGrafx games, you're going to have to change the .pce
extensions to .sg or .sgx. Or you can manually move the games from the
PC Engine folder to the SuperGrafx folder and change the game folder
extensions. I have no way to tell the games apart. Mednafen uses CRC32
comparisons, and I may consider that since there's only five games, but
I'm not sure yet.
The only SuperGrafx game that's playable right now is Aldynes. And the
priorities are all screwed up. I don't understand how the windows or the
priorities work at all from sgxtech.txt, so ... yeah. It's pretty
broken, but it's a start.
I could really use some help with this, as I'm very lost right now with
rendering :/
-----
Note that the SuperGrafx is technically its own system, it's not an
add-on.
As such, I'm giving it a separate .sys folder, and a separate library.
There's debate over how to name this thing. "SuperGrafx" appears more
popular than "Super Grafx". And you might also call it the "PC Engine
SuperGrafx", but I decided to leave off the prefix so it appears more
distinct.
