I'll post more detailed changes later, but basically:
- fixed Baldur's Gate bug
- guess if no flash ROM ID present (fixes Magical Vacation, many many
others)
- nall cleanups
- sfc/cartridge major cleanups
- bsxcartridge/"bsx" renamed to mcc/"mcc" after the logic chip it uses
(consistency with SGB/ICD2)
- ... and more!

[jessedog3, Cydrak]
- controller selection will check the default item in the menu now on
game load
- as usual, a whole lot of other stuff I'm forgetting
Known issues:
- type-ahead find does not work in list views (eg game selection
dialog); I don't know how to fix this
- there's no game file importer yet
- there's no shader support yet
- there's no profiler available for the timing panel, you need to adjust
values manually for now

GBA timings are *almost* perfect now. Off by 1-3 cycles on each test,
sans a few DMA ones that seem to not run at all according to the numbers
(crazy.)
byuu says:
Fixes SuperFX fmult, lmult timings; rambr, bramr and clsr assignment
masking. Implements true GBA ROM prefetch (buggy, lower test score, but
runs Mario & Luigi without crashing on battles anymore.)
byuu says:
Lots more timing improvements to GBA emulation. We're now ahead of
everything but mGBA.
Mario & Luigi is still hanging in battles, so I guess my prefetch
simulation isn't as good as Cydrak's previous attempt, no surprise.
byuu says:
This WIP scores 448/920 tests passed.
Gave a shot at ROM prefetch that failed miserably (ranged from 409 to
494 tests passed. Nowhere near where it would be if it were implemented
correctly.)
Three remaining issues:
- ROM prefetch
- DMA timing
- timers (I suspect it's a 3-clock delay in starting, not a 3-clock into
the future affair)
Probably only going to be able to get the timers working without heroic
amounts of effort.
MUL timing is fixed to use idle cycles.
STMIA is fixed to set sequential at the right moments.
DMA priority support is added, so DMA 0 can interrupt DMA 1 mid-transfer.
In other news ...
I'm calling gtk_widget_destroy on the GtkWindow now, so hopefully those
Window_configure issues go away.
I realize I was leaking Display* handles in the X-video driver while
I was looking at it, so I fixed those.
I added DT_NOPREFIX so the Windows ListView will show & characters
correctly now.
byuu says:
This WIP does substantially better on endrift's GBA timing tests. Still
not perfect, though. But hopefully enough to get me out of dead last
place. I also finally fixed the THUMB-mode ldmia bug that jchadwick
reported.
So, GBA emulation should be improved quite a bit, hopefully.
byuu says:
Added AWJ's fixes for alt/cpu (Tetris Attack framelines issue) and
alt/dsp (Thread::clock reset)
Added fix so that the taskbar entry appears when the application first
starts on Windows.
Fixed checkbox toggling inside of list views on Windows.
Updated nall/image to properly protect variables that should not be
written externally.
New Object syntax for hiro is in.
Fixed the backwards-typing on Windows with the state manager.
NOTE: the list view isn't redrawing when you change the description
text. It does so on the cheat editor because of the resizeColumns call;
but that shouldn't be necessary. I'll try and fix this for the next WIP.
byuu says:
This updates higan to use the new Markup::Node changes. This is a really
big change, and one slight typo anywhere could break certain classes of
games from playing.
I don't have ananke hooked up again yet, so I don't have the ability to
test this much. If anyone with some v094 game folders wouldn't mind
testing, I'd help out a great deal.
I'm most concerned about testing one of each SNES special chip game.
Most notably, systems like the SA-1, HitachiDSP and NEC-DSP were using
the fancier lookups, eg node["rom[0]/name"], which I had to convert to
a rather ugly node["rom"].at(0)["name"], which I'm fairly confident
won't work. I'm going to blame that on the fumes from the shelves I just
stained >.> Might work with node.find("rom[0]/name")(0) though ...? But
so ugly ... ugh.
That aside, this WIP adds the accuracy-PPU inlining, so the accuracy
profile should run around 7.5% faster than before.
byuu says:
This will easily be the biggest diff in the history of higan. And not in
a good way.
* target-higan and target-loki have been blown away completely
* nall and ruby massively updated
* phoenix replaced with hiro (pretty near a total rewrite)
* target-higan restarted using hiro (just a window for now)
* all emulation cores updated to compile again
* installation changed to not require root privileges (installs locally)
For the foreseeable future (maybe even permanently?), the new higan UI
will only build under Linux/BSD with GTK+ 2.20+. Probably the most
likely route for Windows/OS X will be to try and figure out how to build
hiro/GTK on those platforms, as awful as that would be. The other
alternative would be to produce new UIs for those platforms ... which
would actually be a good opportunity to make something much more user
friendly.
Being that I just started on this a few hours ago, that means that for
at least a few weeks, don't expect to be able to actually play any
games. Right now, you can pretty much just compile the binary and that's
it. It's quite possible that some nall changes didn't produce
compilation errors, but will produce runtime errors. So until the UI can
actually load games, we won't know if anything is broken. But we should
mostly be okay. It was mostly just trim<1> -> trim changes, moving to
Hash::SHA256 (much cleaner), and patching some reckless memory copy
functions enough to compile.
Progress isn't going to be like it was before: I'm now dividing my time
much thinner between studying and other hobbies.
My aim this time is not to produce a binary for everyone to play games
on. Rather, it's to keep the emulator alive. I want to be able to apply
critical patches again. And I would also like the base of the emulator
to live on, for use in other emulator frontends that utilize higan.
byuu says:
New terminal is in. Much nicer to use now. Command history makes a major
difference in usability.
The SMP is now fully traceable and debuggable. Basically they act as
separate entities, you can trace both at the same time, but for the most
part running and stepping is performed on the chip you select.
I'm going to put off CPU+SMP interleave support for a while. I don't
actually think it'll be too hard. Will get trickier if/when we support
coprocessor debugging.
Remaining tasks:
- aliases
- hotkeys
- save states
- window geometry
Basically, the debugger's done. Just have to add the UI fluff.
I also removed tracing/memory export from higan. It was always meant to
be temporary until the debugger was remade.
byuu says:
I've completely redone the ethos InputManager and ruby to work on
HID::Device objects instead of one giant scancode pool.
Currently only the udev driver supports the changes to ruby, so only
Linux users will be able to compile and run this WIP build.
The nice thing about the new system is that it's now possible to
uniquely identify controllers, so if you swap out gamepads, you won't
end up with it working but with all the mappings all screwed up. Since
higan lets you map multiple physical inputs to one emulated input, you
can now configure your keyboard and multiple gamepads to the same
emulated input, and then just use whatever controller you want.
Because USB gamepad makers failed to provide unique serial#s with each
controller, we have to limit the mapping to specific USB ports.
Otherwise, we couldn't distinguish two otherwise identical gamepads. So
basically your computer USB ports act like real game console input port
numbers. Which is kind of neat, I guess.
And the really nice thing about the new system is that we now have the
capability to support hotplugging input devices. I haven't yet added
this to any drivers, but I'm definitely going to add it to udev for v094
official.
Finally, with the device ID (vendor ID + product ID) exposed, we gain
one last really cool feature that we may be able to develop more in the
future. Say we created a joypad.bml file to include with higan. In it,
we'd store the Xbox 360 controller, and pre-defined button mappings for
each emulated system. So if higan detects you have an Xbox 360
controller, you can just plug it in and use it. Even better, we can
clearly specify the difference between triggers and analog axes, and
name each individual input. So you'd see "Xbox 360 Gamepad #1: Left
Trigger" instead of higan v093's "JP0::Axis2.Hi"
Note: for right now, ethos' input manager isn't filtering the device IDs
to look pretty. So you're going to see a 64-bit hex value for a device
ID right now instead of something like Joypad#N for now.

Changelog:
- GBA: SOUND_CTL_H is readable, fixes sound effects in Mario&Luigi
Superstar Saga [Cydrak] (note: game is still unplayable due to other
bugs)
- phoenix/Windows: workaround for Win32 API ListView bug, fixes slot
loading behavior
- ruby: added udev driver for Linux with rumble support, and added
rumble support to existing RawInput driver for XInput and DirectInput
- ethos: added new "Rumble" mapping to GBA input assignment, use it to
tell higan which controller to rumble (clear it to disable rumble)
- GBA: Game Boy Player rumble is now fully emulated
- core: added new normalized raw-color palette mode for Display
Emulation shaders
The way rumble was added to ethos was somewhat hackish. The support
doesn't really exist in nall.
I need to redesign the entire input system, but that's not a change
I want to make so close to a release.

[Cydrak, byuu]
- SNES/accuracy profile hires color blending improvements - fixes
Marvelous text [AWJ]
- fixed a slight bug in SNES/SA-1 VBR support caused by a typo

Settings->Advanced
- system profiles, shaders and cheats database can be stored in "all
users" shared folders now (eg /usr/share on Linux)
- all configuration files are in BML format now, instead of XML (much
easier to read and edit this way)
- main window supports drag-and-drop of game folders (but not game files
/ ZIP archives)

refactoring to date)
One highly desired target for this release was to default to the optimal
drivers instead of the safest drivers, but because AMD drivers don't
seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD
has too big a market share. Hopefully with v093 officially released, we
can get some public input on what AMD doesn't like.
