Note: you will need the new icarus (and please use the "no manifest"
system) to run GBA games with this WIP.
Changelog:
- fixed caching of r(d) to pass armwrestler tests [Jonas Quinn]
- DMA to/from GBA BIOS should fail [Cydrak]
- fixed sign-extend and rotate on ldrs instructions [Cydrak]
- fixed 8-bit SRAM reading/writing [byuu]
- refactored GBA/cartridge
- cartridge/rom,ram.type is now cartridge/mrom,sram,eeprom,flash
- things won't crash horribly if you specify a RAM size larger than
the largest legal size in the manifest
- specialized MROM / SRAM classes replace all the shared read/write
functions that didn't work right anyway
- there's a new ruby/video.glx2 driver, which is not enabled by default
- use this if you are running Linux/BSD, but don't have OpenGL 3.2 yet
- I'm not going to support OpenGL2 on Windows/OS X, because these OSes
don't ship ancient video card drivers
- probably more. What am I, clairvoyant? :P
For endrift's tests, this gets us to 1348/1552 memory and 1016/1260
timing. Overall, this puts us back in second place. Only no$ is ahead
on memory, but bgba is even more ahead on timing.
byuu says:
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!

Changelog:
- synchronizes lots of nall changes
- changes displayed program title from tomoko to higan(*)
- browser dialog sort is case-insensitive
- .sys folders look at user-selected library path; no longer hard-coded
Tried to get rid of the file modes from the Windows browser dialog, but
it was being a bitch so I left it on for now.
- The storage locations and binary still use tomoko. I'm not really sure
what to do here. The idea is there may be more than one "higan" UI in
the future, but I don't want people to go around calling the entire
program by the UI name. For official Windows releases, I can rename
the binaries to "higan-{profile}.exe", and by putting the config files
with the binary, they won't ever see the tomoko folder. Linux is of
course trickier.
Note: Windows users will need to edit hiro/components.hpp and comment
out these lines:
#define Hiro_Console
#define Hiro_IconView
#define Hiro_SourceView
#define Hiro_TreeView
I forgot to do that, and too lazy to upload another WIP.

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:
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.

Changelog:
- added Cocoa target: higan can now be compiled for OS X Lion
[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
- added support for multi-pass shaders that can load external textures
(requires OpenGL 3.2+)
- added game library path (used by ananke->Import Game) to
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)
- audio buffer clears when entering a modal loop on Windows (prevents
audio repetition with DirectSound driver)
- a substantial amount of code clean-up (probably the biggest
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.
